Let's drone out. [4.48] AndyRC: We would like to thank all of our Patreons including [8.24] AndyRC: Mikey Dredd as well as Art Faulkner and [13.2] Jack: That's it. We've only got two out of the four twelve dollar Patreons [19.36] Jack: who would help pay for the editing for this train wreck of a show. [24.24] Jack: If you want to get your name read out please donate [28.0] Jack: to patreon.com forward slash Let's Drone Out. [63.12] Jack: Hello and welcome to another fantastic episode of Let's Drone Out. [71.28] Jack: The best UK podcast on drones because I think we're the only one. [77.6] Jack: Tonight we are, tonight we are joined by a special guest, Pawel Stokhowski. [89.6] AndyRC: He says that brilliantly Jack. You have like a shorter version that we can all, [98.32] AndyRC: you know like a nickname like. You just go with Pavel, that's not Pavel. [103.44] Paweł: Just go with Pavel, it will be great. It will be really great. My nickname is [107.6] Paweł: equally hard to pronounce for native English speakers so don't bother. [112.08] Jack: We're also joined by Currykin. Hello. We also have the return of, [120.64] Jack: I don't know, he looks familiar but I'm not too sure who he is. We are joined by NJ Tech. [128.32] Jack: Hello, yes been some time. I've had to sign an agreement not to mention Sophie Ellis-Bekster. [137.12] NJ: Well you've already done it. Are you going to be back for the winter? Yes, yes and no. [145.92] Jack: Do you still even like drones or are you all about Rocket League now? [150.8] NJ: No, of course I love drones. I love both. I love both with not equal measure. I [156.96] NJ: definitely love drones more. Yeah I've put a video back up. It's probably not reached everyone [164.0] NJ: because YouTube does that thing where you can hit the bell icon and it's still beside that, [169.12] NJ: no this person doesn't watch you anymore. So I don't know if people are aware but yes I have [173.44] NJ: uploaded a video and I will be continuing to upload more videos and crack on with various [178.4] NJ: reviews and bits. So yes I'm back. No I haven't disappeared from the hobby. I'm very happy to be [184.72] NJ: fine again and it's really wonderful people. Do you want to shout out your YouTube channel [190.48] NJ: for any listeners? NJ Tech, not the computer one because there's two NJ Tech channels out there [197.44] AndyRC: and I think one of them is software stuff. It's NJ Space Tech or www.youtube.com forward slash [210.88] NJ: Neil Jones guitar. That's the other way that you can also get there. Or just type in the [218.8] NJ: sexiest man that's kind of into FPV. I am into FPV. I've just had to work owned me for the last few [228.8] AndyRC: months. I think it's healthy to have a break from it as well. It must be feel a bit refreshing [236.24] NJ: actually. Yeah it was good. I didn't feel like I fell off the bike too much when I went out [243.04] NJ: flying the other day which was nice. Still got the buzz, still enjoyed it. Still really happy to be [249.52] NJ: getting back into flying. I know this is probably bad timing in terms of the weather and you know [254.72] AndyRC: the way things are going to go. Not at all. It has rained all year. Yeah that's true. Although it's [261.12] NJ: actually it was nice today. We had sunshine. It was very windy but we had lots of sunshine down [265.84] AndyRC: here. This is a problem with the wind. Toothpicks are all the rage and they don't do well in the [274.8] AndyRC: wind. So that's the problem I've been having. It's like yeah it's sunny today but if I fly it [281.52] AndyRC: is that a fair representation of how it actually performs because there's a 50 mile per hour wind. [287.44] Jack: So that's why I've been struggling. Right let me just finish the intro. [292.48] Jack: Right we were also joined by Andy RC. Good evening everyone. My little pet Tony. [300.32] Jack: How do? Or shall I say my what are those meerkats names again? My Sergio. [307.44] Jack: No. Sergey or Alexander. [315.92] Jack: Who knows. They're Russian meerkats anyway. I did have to google it. [320.24] Jack: And he's not stroking himself. He has actually got a dog there. And I am Jack also known as [328.16] Jack: Bright Until I Fly and you're listening to Let's Drone Out. Right so NJ I know you've been gone [333.68] Jack: a while right but there's these weird foam triangles right that look like this. [341.2] Jack: Yeah this lie with only one propeller. I know it is crazy. And you can put like drone flight [353.76] Jack: controllers in them. Right. But you have to flash them with this magic stuff. This is a brilliant [362.88] NJ: snickaway. Keep going. I want to know where he's going with this as well. He's getting there. [370.08] Jack: And you can put GPS on it and everything and you have to flash this software called iNav. [379.68] Jack: I've heard the name once or twice. Yeah and then it does some magic things man. [387.6] Jack: And the airplane crashes to the ground. Yeah if you've got all flies upside down really well. [395.76] Jack: And it was made by a guy called Constantine I think. Yep. And we've got one of your developer [405.84] Paweł: aren't you Val? Yes I'm a software developer. Of iNav. That's my day job. Yeah actually that's [412.24] Paweł: my day job. I'm a software developer. And sometimes from time to time also in the evening [417.12] Paweł: doing iNav and other stuff that's not that popular as iNav. But please donate to iNav. [426.08] Jack: It is life-changing and a lot of fun. And like pal you have a YouTube channel. How did you get [439.04] Paweł: into the RC hobby? That's kind of because like five years ago I decided it's time for me to get [447.92] Paweł: a drone. So I got the cheapest crap I found on the Amazon like, come on, burst motors. And half a [454.48] Paweł: year I decided that maybe I should build myself. I've been building stuff almost all my life. And [460.16] Paweł: then one step to the other I got this. A few months later I decided it's time for me to build [467.12] Paweł: my iReplane and so on and so on. And this is let's say my coincidence. I mean the hobby by pure [472.8] Paweł: coincidence. Because it happened only like four years ago. So it's really like a very very short time. [480.88] Jack: So yeah I've used your videos that you've been very helpful especially with the iNav auto tune [490.64] Jack: and the servo trim as well. You know not realizing that you have to land with auto trim still on [500.32] Jack: and it will save if you disarm. You can always read the documentation which does not exist. [508.32] Curry: Yeah no one it doesn't it doesn't keep up. That did exist actually about auto trim because I was [515.36] Curry: asking Lee about it and I said it's not documented. I looked at the site again I said oh it is now [520.72] Paweł: you have to land with it on. No I think for like two years now the iNav wiki has the documentation [527.84] Paweł: for most of the of the most but truth to be told people usually do not read the documentation. [533.6] Paweł: Especially documentation. I know because I'm not reading documentation. No I yeah I like learning [540.4] Jack: it by osmosis. I mean I think a lot of the iNav wing was covered documentation wise by the [548.48] Jack: rag the nuts off guy. I think he done quite a bit of the documentation. [554.56] Paweł: Yeah it's a original series it's quite good yes. But yeah. And painless of course. I think he was [562.32] Paweł: the first big channel that started doing materials about the iNav for three four years. No how [569.68] Paweł: how old is iNav? Three years? I think something something like three years I think. I will search [577.84] AndyRC: out. Probably Lee that's the biggest channel out wouldn't it be that covers iNav the most? [587.2] Curry: Yeah probably. Yeah. I can look it up hang on. Oh I had a question of of Pavel actually because I [594.96] Curry: watched I was quite interested to watch your video about where's the money go. Where you sort of [600.72] Curry: track down sort of consumer paying the money to retailers. Retailers paying manufacturers [607.28] Curry: and when it comes down to like the software and especially the software developers getting tiny [611.36] Curry: little trickles of it. Which is kind of kind of the way it goes in open source development I guess [617.2] Curry: for most people that are sort of hobbying. Yes yes yes. I was interested because there wasn't [622.48] Curry: really a conclusion there in terms of what do you think the way forward is. Because I think there's [628.0] Curry: always going to be a certain amount of people that will be happy to do it as a hobby and share the [635.68] Curry: code for other people to do it and sort of go on that way. Because the other option seems to be [641.28] Curry: taking it as a commercial endeavor like sort of flight one or something and having your own [646.56] Curry: boards and stuff if people want to make money out of it. What you're taking away to go? [652.72] Paweł: It all depends how you really understand the the open source project and what the developers are [658.48] Paweł: doing. Because from my perspective I love develop. I'm a programmer of my life. I'm developing [664.72] Paweł: software all my life and the fact that I can put a code into something like this magical board and [670.96] Paweł: it does some cool stuff. It's really like very fulfilling for me. And as long as I can only like [676.88] Paweł: when I have some willingness to do something then I just code and it's super cool. No problem as I [683.68] Paweł: talk. But I think I don't know a year maybe a year and a half ago the project called INAF got [691.84] Paweł: into a state that it's really no longer a pure hobby grade software created by one guy because he [700.4] Paweł: likes it. Users started to expect some kind of support to solve their problems and started to [708.8] Paweł: ask for features and so on and so on and so on and so on. If the developers that are in the project [715.44] Paweł: called INAF would spend as much time as the user base expect them because they think that [722.4] Paweł: come on you like programming why don't you program this then it stops being pretty a hobby. It starts [727.68] Paweł: to be almost like a job that you are not paid off. What I do usually I have those phases where I [736.48] Paweł: really do stuff for INAF like last two weeks and probably two next weeks. I'm really like developing [743.12] Paweł: a lot but then probably I will get tired and I will retire from INAF for a quarter few months. [749.44] Paweł: Nobody knows for how long because it's not my job. It's not my job to do stuff for INAF and [757.44] Paweł: INAF cannot hire developers to fix bugs when the bugs are appearing. It only relies on the goodwill [764.96] Paweł: of the guys that are helping to develop the project. So it really depends how you look at it. [771.52] Paweł: If this is only a hobby a way to spend a pleasurable evening because we developers sometimes spend a [779.04] Paweł: pleasurable evening writing the code then it's fine but if you understand this as a business [786.96] Paweł: or really big project that is popular in the community then it's almost like a work and [793.44] Curry: it's not the same anymore. I suppose my question is where's it going to go? Is it the fact that [803.68] Curry: it's become big enough that it's like sort of commercial quality either someone has to [812.88] Curry: take it on and pump a load of money into it or what happens? Do the developers kind of [817.68] Curry: get tired of doing it or the user base is frustrated because they're not getting the [822.72] Curry: fixes they want because of course no one wants to do it all for free or what happens? [828.96] Paweł: The whole market that is interested in paid software is extremely small worldwide. It's [835.84] Paweł: like a few thousand people maybe. From where I see it it's impossible to have a good running [843.52] Paweł: business that will sustain itself and hire two or three developers doing stuff all the time [849.12] Paweł: if you are not selling a hardware because look what are the all the projects that are [854.56] Paweł: commercial right now what they are already selling. If you buy the eagle tree what do you buy? [860.4] Paweł: Software or hardware? You buy hardware and by coincidence you also get the software. [867.52] Paweł: The same goes with flight one the pix hulk yeah okay the pixel is slightly different because [874.72] Paweł: they got commercial sponsorship back over the years. What else? DGI. You buy DGI hardware not [881.6] Paweł: the DGI software. Some time ago I made a poll if people are willing to pay for a special version [888.64] Paweł: of INAF or mobile configurator. People were not interested so there is not enough money in the [895.84] Paweł: hobby in this potential niche to convert this into a project that lives only based on the software [903.84] AndyRC: itself. It's just too small. So how does beta flight do it then because they seem to have [912.32] AndyRC: too many releases and not too many is the wrong term but they have like there seems to be a new [919.2] AndyRC: release every other few weeks. So how is their model different than the INAF? [926.64] AndyRC: You mean beta flight right? [934.0] Paweł: I'm not in the inner circle of the beta flight so I cannot speak for them what's happening inside [940.56] Paweł: but from what I know the amount of money in beta flight as a software development [945.84] Paweł: project is more or less the same as in INAF not existent. With the beta flight it's slightly [952.0] Paweł: different because beta flight on one hand has a simpler let's say simple role. People do not expect [963.52] Paweł: beta flight to run on everything. People expect beta flight to run only from three to let's say [969.68] Paweł: seven inch watts and it's great. And also this is probably right now the most popular let's say [977.76] Paweł: area of the RC hobby people love flying meadrops. So not only a lot of people are buying hardware [985.36] Paweł: but a lot of people are building this kind of quads it's relatively simple and the fact that [992.32] Paweł: they are releasing something does not mean that they are paid for this. You found the back then [998.48] Paweł: let's fix the back let's make a release everybody's happy. But I expect maybe there is some more [1005.92] Paweł: maybe few hundred bucks yearly in the beta flight more than the INAF. Not that the INAF has [1011.52] Paweł: hundreds of bucks because that's also not true but there is also no money. The projects open source [1017.2] AndyRC: projects are underfunded just like that. So maybe it could be the beta flight get more donations [1024.56] AndyRC: than perhaps just because it's more of a popular thing. It's still what I know most of the developers [1031.92] Paweł: of the beta flight are just doing this on a hobby base because this is this is this is cool. They [1036.56] Paweł: know how to make a quad fly better so they make the quad fly better. This is only my let's say [1042.56] Paweł: suspicion over there. And if I recall correctly right now beta flight releases in half year cycle [1051.84] Paweł: they released 4.0 half a year ago now they are preparing to release 4.1. So it's not that they [1059.44] Paweł: are really like releasing everything and and the development is not that fast. Also because the [1065.44] Paweł: user base of the beta flight is higher it's there's it's more probable that also they will find a [1071.44] Paweł: developer that is willing to do some work for the project. It's all an effect of the scale. [1077.52] Jack: Yeah also also like at the at the beginning they're only there was clean flight and then [1084.8] Jack: uh beta or beta in the beginning was multi-way. Well yeah yeah yeah all right well yeah in the [1091.28] Jack: beginning I mean there was base flight there was KK2 there was you know okay but like base flight [1100.4] AndyRC: Jack's just saying beta flight so that because because that's how NJ says it and he wants him [1105.76] Jack: on next week. I can't believe he's back oh look how white those teeth are god damn I swear to god [1120.08] AndyRC: you could make me gay. He doesn't he doesn't like them either they're just like that you know they [1126.08] AndyRC: naturally grew out without anxiety amazing. Spising the amount of coffee I drink actually. [1140.16] Jack: So anyway um there was you know then it forked a clean fly and then uh beta flight was a way of [1150.16] Jack: like having a little sandbox and testing all the the uh push requests or pull requests [1157.36] Jack: and I always get those two mixed up and and and that was that at the beginning and then [1164.0] Jack: it kind of got a hell of a lot of traction because of the amount of work that um the uh Boris B did [1171.12] Jack: really he he put he put a hell of a lot and of of like you know sort of work he would feverishly [1180.0] Jack: work day day and night and then put out a load of releases and um and then you know like only [1188.08] Jack: only now sort of like you know I now have completed about a year or two ago completed its [1196.88] Jack: drone sort of uh side and then really started to pick up the uh fixed wing is that right um no [1207.36] Paweł: a kind of was formed from clean flight more in the same period of time the the beta flight was [1213.6] Paweł: formed for uh clean flight and the flying wing airplane support in let's say almost not change [1223.12] Paweł: basic way uh is there really from the beginning because all of that already existed in the base [1232.08] Paweł: flight all of that already existed on the on the clean flight only Constantine back in the I think [1239.12] Paweł: it was 2016 or 2015 in the event started refining this refining this but the project and the making [1248.16] Paweł: this better for the airplanes uh actually yeah something like uh last year ago I think with 2.0 [1256.64] Paweł: with the rewritten mixer and the better graphical interface to set up mixer and things like that [1262.64] Paweł: what we are gradually refining the product at making this better blah blah blah blah blah blah [1269.36] Paweł: and catching up a better flight and some of the features because uh let's be honest right now [1274.48] Paweł: meta flight is the the software you have to look at when you want features and flight performers [1281.76] Paweł: for the quads not only mini quads but for the quads so I will not let's say exaggerate when I [1289.28] Paweł: say that we get from meta flight a lot because both projects are open source under the same license [1296.08] Paweł: we just take whatever we want from their coat and they take whatever they want from our coat [1301.6] Paweł: not that they they take a lot but it's always there anyone can take whatever whatever they want [1308.24] Jack: um yeah because I remember like you know when I first started using iNav I mean there you would [1316.56] Jack: calibrate your um board and you wouldn't be able to tell which axis you've you've done you'd have to [1324.24] Jack: rhythmically follow the wiki and everything yeah well good old times good old times let's say but [1332.48] Paweł: this is this is always the problem that iNav has a higher entry level because you have to [1339.04] Paweł: set up much more things and the setup of the things is much harder and we have slightly [1345.52] Paweł: less developers or the smaller user base so it's harder for us to find developers um this is why [1352.72] Paweł: very often the development base is not really that rapid as we would like for example we still [1359.28] Paweł: do not have a good support for smart audio 2.1 because we don't have time we don't have hardware [1366.24] Paweł: and we don't have let's say immediate need to to finally patch it in the in the correct way [1372.72] Jack: um who who out of us uses uh iNav I mean I know I've downloaded iNav um just to take a look at it [1385.2] AndyRC: and um yeah it's a it's surprising to me um because it just looks so similar to [1393.36] AndyRC: betaflight I assumed they were more closely connected um than than it then it appears to be [1401.2] AndyRC: but uh essentially you're just sharing the interface because it's both open source and [1408.16] AndyRC: it's a sort of interface that people are familiar with so you can sort of cross over I guess it's [1415.04] Paweł: the idea of going with that interface we really share a lot with betaflight key in flight and [1421.36] Paweł: even base flight you always have to remember about base flight because all the projects originated [1426.96] Paweł: from the same code base they originated from the rewritten multi-way which was the back then called [1433.2] Paweł: the base flight configurator internals of all three three I'm not sure if you actually recount [1440.08] Paweł: the clean flight as a separate project right now uh the interface is the the interface that the [1446.72] Paweł: backbone of the software is more or less the same the film works share the same libraries they [1452.48] Paweł: share the same CPUs a lot of things are similar but because come on that I would if I would have [1458.48] Paweł: to guess like 50 percent of the code base is exactly the same in both projects because they [1463.68] Paweł: originally originally from the same the same uh the same place only they diverged from the beginning [1470.0] Paweł: and they started let's say have a different purpose when betaflight always concentrated or [1477.2] Paweł: the miniquets while enough concentrated in the beginning on the on the retro to home waypoints [1484.64] Paweł: and slightly better navigation and then there was the aeroplane phase multi-rotor catch-up from [1491.76] AndyRC: betaflight and so on and so on and so on so um from from a from like a multi-rotor perspective [1500.24] AndyRC: this has always interested me because um I think one of the reasons that uh people like get out of [1510.4] AndyRC: multi-rotors is because there's no redundancy you know there's no flip a switch if I get into [1517.92] AndyRC: trouble and gps kicks in and it just loiters there and inav has the possibility to do that [1525.76] AndyRC: so that's what interested me about inav so are there um from from what I hear you know um the [1536.08] AndyRC: the acro performance in inav isn't on par with betaflight is that fair to say and is it sort of [1544.16] AndyRC: um it is it a uh something that a direction that inav would go into to try to show [1555.2] Paweł: you want my honest opinion I will never say that inav is actually on the same level of performance [1562.88] Paweł: uh in the miniquets world as the betaflight is but it's not true but I currently own like [1570.72] Paweł: one two three four five five maybe six mini quads if you count seven inches seven inches [1576.48] Paweł: and and the 3d printed tricopter yeah yeah I'm not flying I'm not even counting that [1582.64] Paweł: guess how many of those quads inav enough uh powers and I'm flying them freestyle [1589.92] Paweł: racing stuff like that not only I some of them even don't have gps it's one only one because [1597.84] Paweł: uh of the hardware on this one is not supported by the inav but that's all if I would have to [1606.72] Paweł: guess right now the acro performance of inav if you tune it up correctly because you have to tune [1612.96] Paweł: inav uh the envelope of hardware for inav is much much wider than for betaflight but if you tune it [1620.88] Paweł: by experimenting on watching some of my videos and stuff like that the performance is some [1627.6] Paweł: were on the betaflight 3.5 level it's not 4.0 because we lack the dynamic filtering [1636.64] Paweł: uh but if we would add the dynamic filtering which I'm quite often thinking maybe I should [1642.56] Paweł: report it finally then the performance would not be really that difference there is a performance [1648.08] Paweł: difference they behave slightly slightly different uh but if you go to my channel and watch some of [1654.96] Paweł: the flight videos I publish from time to time all of those were recorded with eye efforts pretty [1662.0] Paweł: I'm not the best pilot in the world but the software does its job this episode was recorded [1668.32] Frank: in front of a live online audience downloaded and edited to make sense when it played audio only [1673.68] Frank: censored to please the itunes people hosted on the internet forwarded through to your podcast [1677.76] Frank:

patreon.com [1689.92] Curry: forward slash let's drone out what do you think of um and did this come from inav did betaflight [1697.2] Curry: get their gps they call it kind of rescue mode yes and this is the rescue mode the crash towards [1703.92] Curry: yourself is what I like to call it did did this come from inav or did betaflight dream it up by [1708.56] Paweł: themselves no they they developed this by themselves this is 100 percent they're doing [1714.96] Paweł: which is like the the name says it's a rescue if you really got into a trouble then you the quad [1721.2] Paweł: will probably return home somehow and then drop close to you yes and this works great in that [1727.92] AndyRC: that aspect it almost seems a shame that um the the two don't sort of like from a developer [1744.72] AndyRC: perspective come together because I just love to see a uh an entire package where you have that gps [1753.68] AndyRC: redundancy but then you've got the the flight performance of betaflight and then you could [1761.84] AndyRC: you you could have the the full deal you know this this so what are we looking at um this [1771.2] Paweł: is a seven incher if I would replace the motors with slightly stronger version this would be [1776.16] Paweł: pretty nice seven inch with full return to home and night operations capability but no um like I [1782.32] Paweł: said you have to tune enough you have to do all the in theory it is possible for us to use exactly [1791.68] Paweł: the same but very close defaults that betaflight uses this is possible we the p values in both [1799.52] Paweł: softwares can be set to exactly the same value i can be set to exactly those same values the d and [1806.88] Paweł: fit forward let's say slightly slightly different story you really have to tune d and fit forward [1812.64] Paweł: okay there's no fit forward in the ina but the filters the basic filters are more or less the [1817.36] Paweł: same if we would apply then it would fly mini quads just as fine as betaflight without any extra tuning [1826.72] Paweł: at least for majority of the users but we cannot do it uh people fly 10 inches 12 inches people [1833.76] Paweł: really fly a very wide uh i understand and they put really extremely extremely strange things into [1843.52] Paweł: the air so we are not even pretending that uh you just flash and and take it to for a spin and it will [1850.56] Paweł: work i i maybe if i will have time for the next release of i enough i will implement a feature [1860.56] Paweł: that will have a possibility to have different defaults because there is idea how to more or less [1867.28] Paweł: do it maybe this will make the whole process simpler but still the i enough has in the [1871.76] Paweł: configurator the whole section called presets when you just more or less choose your type of [1876.88] Paweł: the uav and drone or and click apply presets and the preset is applied so then at least filtering [1883.36] Paweł: and pizza are more or less to the class more or less you then still have to tune it yeah yeah no [1892.0] Jack: no practical that's great i i done my s800 with the presets and it flew beautifully right off the [1899.2] Jack: bat i was i was really impressed well because the defaults are useless in i enough i will honestly [1911.52] Paweł: say it the default values of the pit gains and the filtering is really absolutely nothing good [1918.96] Paweł: flies flies good on those values because we don't know what users will be flying with will it be a [1926.08] Paweł: big small heavy light three inches seven inches we have absolutely no idea so we just do not set [1935.36] Paweł: defaults for a specific class and this is absolutely the reason majority of users [1941.04] Paweł: thinks that after flashing kind of and taking into the area observing how crappy it flies say [1946.4] Paweł: that i enough is crappy software because then that the defaults are crappy that's all what would you [1953.2] Paweł: recommend doing trim first then tune make it not on the on the flying wings and i replace in general [1962.56] Paweł: like on monday i published a video of the full process that means they set up the center of [1968.16] Paweł: gravity well then set up rates auto tune auto trim no auto trim auto tune and then manually [1976.48] Paweł: improve the tune this is this is the way with the multirotors go to the presets apply the [1983.2] Paweł: preset that you think is closer to what you fly hopefully for the next release we will update the [1989.52] Paweł: the presets that maybe put some more over there and unfortunately you have to learn how to at [1996.72] Paweł: least basically tune your multirotor because without that it's impossible think think what [2004.16] Paweł: happens when you flash a better flight on the three inch will it fly on defaults oh absolutely [2011.28] AndyRC: no no it you arm it and it just flies the sky on its own exactly exactly it didn't used to do that [2019.52] AndyRC: it's only since be a flight before it started doing that to be fair but what is what is interesting [2025.84] AndyRC: and tony's is but is buggered off but um he uh flies x class but i think he's using [2033.28] AndyRC: bit of flight jack if i'm not am i right yeah i think so yeah yeah so those are those are running [2040.88] AndyRC: like um what are they 12 13 inch blades so um but but but you're absolutely right um yeah the the [2053.52] AndyRC: three inch and below completely different pads completely different different [2061.36] Paweł: different moment of inertia on the frame completely different frequencies of the noise from the motors [2067.6] Paweł: completely different uh trust to moment of inertia right show because when we do trust to wait we [2074.4] Paweł: simplify stuff incredibly how trust to wait is only like 10 percent of the story trust to inertia [2082.24] Paweł: is more important moment of inertia and everything is completely different that defaults [2088.08] Paweł: on the beta flight are that good for one year old quad and it works great you put yourself [2096.64] Paweł: bigger motors i don't have example oh no there's for example oh this thing this thing had different [2106.08] Paweł: motors uh 2306 i replaced the motors with 2208 which has like 40 more torque and they [2117.92] Paweł: completely had to return it defaults were absolutely not working the p gains had to [2122.8] Paweł: be lower by 40 percent to make distinct flying the defaults are only good on the stuff that you [2131.6] AndyRC: design the side that defaults for yeah which in beta flight is essentially a five inch [2139.68] AndyRC: or freestyle copter from what i experienced something like that yeah even if you would [2146.8] Paweł: put defaults on the really current up to date really torquey powerful five inch chair [2153.28] Paweł: it still would fly crappy and over oscillate because the current motors have [2158.4] Paweł: whoa that much torque than the one year old generation of motors so what you're saying is [2165.76] AndyRC: that then with inav that you can you probably can get acro close to be close close not not [2174.48] AndyRC: quite but close that's interesting yeah because because that's something that i that's an avenue [2179.44] AndyRC: i want to go down with um i recently um tried it with mission planner because there's been a sort [2187.04] AndyRC: of resurgence with arju pilot and arju copter ever since it moved to that shivios am i saying [2195.36] AndyRC: that right shivios um so um yeah and someone came up with a set of defaults for like a 250 mini quad [2204.88] AndyRC: and yeah it wasn't bad and you could flick a switch and uh you could be an acro flick a switch [2211.6] AndyRC: and then it it returns to home and uh yeah that's that that's the kind of thing i think beginners [2218.24] AndyRC: need um you know if if they want to go straight to a mini quad um so so that's sort of what i'm [2226.72] AndyRC: interested in with with inav um rather than rather than the the wing stuff although um planes you [2234.56] AndyRC: know is is what i've done the majority of my life i just don't have the space for planes [2240.72] AndyRC: otherwise every my channel would just be all plane stuff i flew i flew a um i flew a bixler [2250.64] AndyRC: three on tuesday with fpv set up and everything and it was uh yeah i really it was it was awesome [2258.64] AndyRC: yeah phil if you're watching he let me fly his bixler and i'd never flown one before and yeah [2265.44] Paweł: it was cool i liked it so no the the performance can be close but you have to let's say know what [2272.72] Paweł: you are doing start from the presets we implemented in the configurator and then try to tune from [2279.68] Curry: there and yeah you will get somewhere i suppose the question is looking at some of us who are [2287.6] Curry: a bit lazy for tuning and i i hold my hands up hold heartedly because my lack of time means i [2293.52] Curry: just want to go there and fly uh you know oh this is going to work i i mess with my p's and d's [2299.12] Curry: but as soon as it's flying okay i'm like okay i'm going to fly this what do you think the possibilities [2304.48] Curry: are having uh an auto tune that is good enough to get you into a really quite solid flying situation [2312.0] Curry: on any size quad let's just define a solid um you won't sort of think oh it's oscillating or it's [2320.88] Curry: making a noise basically it will just it will just fly nicely i mean one could say okay we could [2327.68] Curry: spend an extra couple of hours tuning it and fine tuning again it absolutely is perfect but [2334.16] Curry: something that would just be like this is this is fine pretty well out of the box that sort of [2338.32] Paweł: solid i'm not sure if you remember when clean flight four-year-old clean flight there were [2344.88] Paweł: some auto tunes there was a g tune there was something else tune it was kind of tuning stuff [2351.76] Curry: i think i tried it and i remember trying it out and it was hilarious because you had the [2357.36] Curry: cord just went i'm over here and it do this sort of thing for a while and then it would drift away [2363.76] Curry: and you had to bring it back and there i managed to get it finished once and it was really bad [2368.8] Paweł: there is really a lot of literature how to tune pit controllers there are [2374.16] Paweł: mathematic equations you can read about those stuff i don't remember right now the names of [2379.04] Paweł: all those algorithms but you if you know the oscillation frequency and then this happening [2385.04] Paweł: then you can really tune it you can really tune it and i bet that if someone really had enough [2390.96] Paweł: time and willingness to implement one of those scientifically proved methods of tuning [2397.68] Paweł: of the quadcopter because quadcopter is really like it's every other machine you can control [2403.04] Paweł: with pit controller pid controller it's not a different but you tune your pid controller [2410.96] Paweł: while working that means it would have to let's let's say start doing those crazy stuff in the air [2418.32] Paweł: for the learning algorithm to pick up the uh resonance frequency and then apply this apply [2425.84] Paweł: this up so it will always look like something is happening if you move to one step too far then [2431.92] Paweł: something exploded somewhere this is by the way exactly the the way how the autotune is working [2438.24] Paweł: on the i replace it just compares your input with your output and you have to do stuff with the [2445.36] Paweł: sticks for this to work and tries to match mainly fit forward mainly fit forward so your output [2453.68] Paweł: matches the input but this works on flying wings because flying wings and airplanes in [2458.8] Paweł: general have lot of built-in stability they will not flip over if you slightly mess your tune [2466.0] Paweł: they will still fly only not as good but maybe someday someone but i really honestly doubt it [2472.88] Paweł: the tuning of the quad is really simple you know it's really like if you know how to do it then [2479.68] Paweł: it's simple of course if you're not very lazy no if you know how to do it because it takes like [2485.92] AndyRC: 10 minutes i'll have to have a try of it it's something i've not tried but it's something [2492.96] AndyRC: it's it's on the the to-do list it's just the problem is the to-do list is endless at the moment [2499.84] Paweł: so yeah i know i know the feeling uh and again endless to-do list yeah so i'd really like to [2506.88] AndyRC: check it out though so um yeah i've got i've got it in my i downloaded and installed it and i've [2513.6] AndyRC: looked around and watched a few videos but that's about as far as i've gotten but uh i eventually [2520.8] AndyRC: plan to to try and do what i did because uh when when when i uh got reunited with mission planner [2529.28] AndyRC: it was a two-week endeavor to try and remember how everything worked and so it's like it's like [2536.0] AndyRC: learning something new isn't it you know and then there's so much to look there's so much to learn [2541.44] AndyRC: in this hobby in the first place where you know your brain is just full of stuff and i i need to [2548.48] AndyRC: like delete some useless stuff to make some room for some i-nav things and then and then i'm ready [2556.16] AndyRC: i think but um sorry to sort of go off topic because i know like we're coming close towards [2562.96] AndyRC: the end um we we don't we don't have uh andrew slash frank to talk about this um but do any of [2571.6] AndyRC: you guys have any insight on what's going on with the bmfa as i think the short version i saw was [2579.44] Jack: don't register or something like that yeah don't register yeah you you were funny enough you were [2586.08] Paweł: covering uh eu drone laws as well uh yes but from what i've heard you are leaving the european union [2594.64] Paweł: so i don't care about you not any time soon yeah i doubt it will really happen now no uh so [2608.48] Paweł: from what i've heard the the rules that you are planning are kind of similar to what will be [2615.36] Paweł: happening in the european union but i don't know anything about the test you're supposed to be [2619.52] AndyRC: taking so don't ask me yeah it was more it was more sort of to jack and don't register yeah it's still [2628.48] Jack: being worked out i reckon the price is going to change and all this and that this is why i i [2635.68] AndyRC: really struggle to to you know pay attention to any of this because it changes on like should have [2642.56] Jack: got an email about it basically i got yeah yeah that that's how i know about it because [2647.92] AndyRC: my friend phil actually said oh i got notified by the bmfa today about something about register [2654.16] AndyRC: the registration thing i was like oh man it's like one minute it's a tragedy and the next [2660.48] AndyRC: minute it's like oh everything's gonna be fine and then it's oh no and then oh brilliant and it's like [2667.36] AndyRC: should do we just not pay attention to it until something actually happens because it seems like [2674.32] AndyRC: you know we're just preparing for something that just hasn't been decided yet you know [2681.2] AndyRC: just just seems strange um but yeah so that uh it's slightly off topic there but i just wanted [2688.96] AndyRC: a fan of you guys now we needed andrew slash frank for that one really didn't we more more [2695.52] AndyRC: in tune with that but uh i just thought i'd mention it because it's something that's going [2699.52] AndyRC: on here in the uk bmfa is the the british model flying association so like that that [2706.24] Paweł: i'm not sure what i think is it i think this is the situation currently in all the european [2713.2] Paweł: union countries including great britain um because from what i know yeah the european union [2722.72] Paweł: got those regulations out but for example the polish authorities because i'm from poland but [2728.72] Paweł: i do not live in poland uh are only just planning to do something about this because there's the [2735.04] Paweł: rules from from the above from the european union they're on the general direction and how it's [2740.88] Paweł: going to look like in the end really depends on the on the national regulators with what kind of [2746.8] AndyRC: the rules that each country will come up with yeah so when this uh posted in the chat uh a facebook [2756.96] AndyRC: post i think uh to it so yeah we can all go and read that also someone has said nj's gone quiet [2766.24] AndyRC: why is that it's been a game man is this is learning nj's learning now here it's just [2773.84] NJ: yeah i'm just i'm this part of my absorbing phase where i reabsorb reabsorbed the now [2779.52] NJ: and then i will have do you have a mess around with i now ben j no not something i messed around [2788.72] NJ: with i did um when the gps thing became something people were testing in bait flight i did a bit of [2796.8] NJ: that and got uh one of my quads still mounted up there but the gps got the return at home [2801.36] NJ: and all those bits and bobs working but yeah i'd certainly like to see more of that developed on [2808.88] NJ: or that developed four quads because it's uh it's useful and it's uh as as was mentioned there's no [2815.2] NJ: real redundancy for mini quads but that is an offering shall we say that um would certainly [2821.44] Curry: be useful for some people [2832.24] Curry: i say it's great fun when you mess it up in your wing mine flew upside down instantly [2836.24] Curry: because i'd managed to reverse servos in my radio but not to inav so from my [2843.68] Curry: from my manual point of view please yes rookie yeah the rookie mistake but it's good it's making [2850.8] Paweł: mistakes good for learning extremely popular mistakes uh on one of the polish um rc groups [2859.6] Paweł: the topic of where to do the reverses on the service for i enough is popping up every month [2864.72] Paweł: or something because the people really like try to do it all the way make the reverses in the in [2869.84] Paweł: the radio and this always always ends very very badly yeah at least one decent thing is when you're [2877.2] Curry: flying a wing and you're like you're in manual you'll take it up to 100 meters then you'll flick [2882.08] Curry: a switch and if it turns upside down you've got loads of time to un flick the switch turn it back [2887.04] Curry: over and land it's not quite like the fun stuff of quad flying trying a new mode i don't know about [2892.64] Curry: you nj but i was kind of sweating the first time i i said let's do a gps rescue and see what happens [2897.44] Curry: uh uh it's some some you know i'm not so fusion that it actually came back i kind of had some [2905.68] NJ: i had some inadvertent training with things being reversed not by actually practicing it as such but [2912.72] NJ: when i used to fly when all i did was fly rc helicopters and i started flying 3d [2919.2] NJ: when you take a helicopter and you flip it upside down and you reverse the pitch on the blades [2923.76] NJ: when the helicopter is actually upside down half the controls become reversed just by the [2930.16] NJ: nature of the way the collective works so in order to fly in what's essentially rate mode [2935.44] NJ: when you're upside down with the helicopter if the tail's away from you then uh pitch is correct [2943.2] NJ: but ailerons are reversed so i had to learn to fly in that orientation and then if the helicopter [2949.52] NJ: would swing around pitch would be incorrect but ailerons would be right it would basically always [2954.72] NJ: change the way you had to control it so whenever i messed up and put something in wrong and gone [2960.72] NJ: out and flown it i've been able to survive it but obviously that's a really expensive way to learn [2965.28] NJ: how to do that because helicopters are expensive and you don't want to crash them um but yeah that [2971.52] NJ: i know multiplies helicopters yeah yeah i've still got them sitting in the loft i will get [2977.76] NJ: the mountain flying again one day but they look cool though they are there's nothing [2984.88] NJ: especially electrics because they sound like jet engines anyway i don't know to me they just [2989.28] Curry: dangerous whenever i i've only seen one at fpv meet and it was only a 450 size which you'd think [2995.6] Curry: is quite small so he starts up and the rotor starts spinning and you can just feel everybody [3000.4] NJ: moving back moving back it's like it's still it's still increasing it's the most intimidating [3007.52] NJ: thing about the small helicopters is not the what makes them intimidating is actually the rpm of the [3013.92] NJ: rotors because the larger heli i've got 700 size helicopter which is is just a monster and a 600 [3020.4] NJ: and they're both running but i think the 700 runs between 18 and 2100 rpms 600 millimeter carbon [3029.04] Paweł: he's got a turbine blighter turbo yeah it's a turbo it sounds almost like a helicopter [3039.12] Paweł: printer and it's it's 3d printed it's going to explode you want me to start this thing [3044.64] Paweł: yes yes okay and turn the gain up on your mic uh let me find the radio i want to see mj fly [3057.44] Paweł: um [3059.44] Paweł: radio is powering [3062.08] Jack: hang on let me find the light let me find i've got the link to you making that hang on let me [3068.64] Paweł: grab that the turbo impeller no no no no no no no this is the v2 of the turbo this is like three [3075.76] Jack: times bigger volume than something i showed before okay um i told you this guy's mad [3090.62] Paweł: was that reliable to hear it yeah yeah pretty okay so yeah almost like a heli sounds like it's [3104.46] Jack: gonna explode i hope not long and boring that is a great video like you've come on this show [3115.66] Jack: i've just looked at your newest video long and boring dead [3122.94] Jack: oh man it's long and boring watch it yeah i'll have to i'll have to don't bother it's boring [3130.22] Jack: just like the name says oh no yeah i i i came i can't remember when i came across you but [3139.18] Jack: like i've been subscribed for a while and you know you've got loads of different [3143.98] Jack: projects and that how's the um f7 65 from matex because you've you've got that well i haven't got [3152.78] Paweł: it board is and you've done it somewhere here no it's still well let's say it's there somewhere i [3164.06] Paweł: have nowhere to put it right now the board itself really is looks amazing it's the most powerful [3170.22] Paweł: board ever but it's slightly an overkill you really in majority of the cases don't need that [3179.18] Paweł: much of the voltage stabilizers and the outputs and stuff like that maybe maybe i will upgrade [3186.3] Paweł: one of my wings through this board maybe not i really have not decided yet three video switches [3192.38] Paweł: on it as well isn't there no they're too oddly i think no but it's really a lot of different [3201.02] Jack: stuff so no um it's also nice that someone i don't i don't know someone european on here [3206.94] Jack: because you actually know what a little guider is as well i quite like that episode the they [3213.1] Jack: they're so in in this country we've got like a grocery store supermarket we call them over here [3222.46] Jack: and they sell little little chuck gliders and you chuck it and depending on which way you put the [3227.42] Jack: wing yeah it either goes a distance or it will loop back to you and you catch it again yeah yeah [3233.26] Jack: and um you you modified one of them i've got a friend called dan upton who made the the the [3239.74] Jack: wings tilt i bought him a few of those so you yeah interesting hi talk motor and you just put [3248.54] Paweł: i think you put uh uh flaps on didn't you no no no no that's a simple uh for channel motor [3257.81] Paweł: the secondly the glider is waiting to be built this time with some more interesting capabilities [3262.61] Paweł: like fpv and gps and the new matic board and stuff like that when like and the set the to-do [3269.97] Jack: list is very very long yeah always too long have you have you got anything uh you can [3276.13] Jack: to the latest with what you're working on next have you got like uh got a hint um exclusive [3284.45] Paweł: maybe it's any one of you remembers my project pennies pennies pennies yeah i don't think this [3291.01] Paweł: guy is very ldo project penis yeah yeah there's a video i think that's what ldo was originally [3300.69] Paweł: called wasn't it before a proper name there's an atel uh project coming alone there's a v-tail [3309.81] Paweł: project coming along multi-rotors based on this there's a bicopter which i'm building but is [3315.73] Paweł: constantly failing and i cannot tune this thing there's this lead glider there will be a smaller [3322.29] Paweł: racing wing there is um wait a second i will find the hardware [3328.05] AndyRC: is that the david is that the david wendestall bicopter or is it one of you [3336.32] Paweł: no it's my own 3d printed version well version i idea and there is this i don't know where i [3344.4] Paweł: will finish but i always have it printed um it goes like this there's two servers on this [3351.36] Paweł: and two flaps like this you put it on the drone connect the servers to the flight controller and [3358.08] Paweł: when you pull the throttle down and start to float in the air it will move like that and give [3363.76] Paweł: you small wings right then you open the throttle and it goes back up and fly again when so so a bit [3374.72] AndyRC: like a bit like the osprey then in a way because that kind of does that right in opposite you know [3381.52] AndyRC: the the v22 osprey the uh it's like um tilt tilt rotor now yeah but they tilt the whole wings or only [3391.6] AndyRC: the no no no just just the rotors tilt on them yeah but it just seems like using a wing for [3399.52] AndyRC: efficiency right or is that the idea to to use a way no rather to see what's gonna happen then [3408.88] Paweł: how spectacular it is integrating there fair enough i thought there was a concept there but [3416.24] Paweł: it was like i wonder what happens if i do this yeah exactly yes yes this is half of my doings [3422.4] AndyRC: i wonder what's happened when i do this no concept no concept just yeah all right this this is a [3428.4] Jack: thing i'll try that i like that right guys i think we've made up for the time that we started late i [3436.16] Jack: believe so um wow thank you so much for coming on i hope you had a good time it was yeah it was [3444.48] Paweł: quite pleasure level but yeah it was quite nice yep um we'll get we'll get enjoed to take his [3450.32] Jack: stuff off next time that's the only way i can think of making it better um but yeah you guys [3456.96] Jack: have been listening to lecture now thanks for all the patreons thanks for any donations guys [3461.68] Jack: robert and your legends um hopefully we'll get andrew frank back if not the the the show will go [3471.04] Jack: completely tits up um i am on in a little less than an hour at 10 to 11 i'm on thursday night [3481.28] Jack: show playing eighties music i put the link in the chat and you've been listening to lecture [3485.76] Jack: now you've been joined by uh paval pskowski pskowski uh uh daddy or curry kitten hello [3495.04] Jack: goodbye no the sexy nj tech good to have you back buddy take care guys and everyone's favorite [3504.4] Jack: disclaimer lord andy arcy good evening all and i've been bright until i fly remember donate to [3511.92] Jack: our patreon and donate to inaf fight the good fight enjoy guys have a good night hello and [3521.44] AndyRC: you're listening to let's drone out the best drone based podcast on the internet we would like to [3527.36] AndyRC: thank our patrons including licky dread and also art forkner and lastly that's it we've only got [3537.28] Jack: two of the four patreons that that donate so i have their names read out so [3545.76] Jack: if you want your name read out go to patreon
