Good info Lee! nice work Pavel (and all the other developers) now i'll hurry to update my INAV. thanks guys
Fantastic information Lee, Thank you. I appreciate fellow pilots like you and Pawel who devote much time and energy which really helps everyone. I am starting to get somewhat comfortable with INAV. I have my quad setup to set low power when disarmed but this is another step in stream lining it all. Really look forward to having the dynamic power setup. Thank you again. Roger
Lots of changes in INAV 2.6 so things like dynamic power may be a little easier (crosses fingers!).. Stay tuned!
After watching your second video in this series this now makes much more sense. thank you. brilliant
Thank you Sir for all your awesome work!
I’ve already got the Dart and the Brain is on it’s way.
Can’t wait to go through the build and configuration part and rewatch your Dart series while doing all the steps!
Yes! Took me a while to figure out how to set it by the GPS, but it works awesome. This is great for flying with buddies. Hardest part was working out the XOR logic for the logical conditions.
You need a logic condition for each range (so, is range > where you want it to switch), and then you need an additional logic condition that is XOR so you know when one range is tripped but not the next one. So mine trip at like 100, 500, and 1000 meters. That’s logic 0 1 and 2. Then logic 3 is an XOR for logic 1 and 2. So it tells you it’s more than 100m but less than 500 (because it’s impossible for it to be over 500m and less than 100m at the same time). And that XOR condition is what you use to trip the VTX power.
Wow thats nice, would Love to see a video about this :)
Yep, check out the video in the BrainDART playlist for a preview of the more advanced setup...
Triple likes from me. This is great information and I will certainly use these logical conditions. Cheers.
Please! More on this subject! Great video as always! Thank you
This is a really interesting feature, I am definitely going to give it a try once again a great video, thanks.
Brilliant, perfect timing as I am just busy with rejigging my Goblin and was lookign for a way to control the power level because I start off with 25mw launch and then realise I forgot to up it, have to land, set it, then launch again. All wastes battery and I was hoping I could do it from the tx.
Awesome stuff! Missed this one. Thanks!
That's actually really interesting, Lee! Thanks a bunch! 😃
More videos about this kind of stuff... Sure, please! 😃
BTW, Pawel is a great guy!
YES!!! I've recently tried and failed to setup both of vtx power and flaperons on logical conditions. So this and pavels video about flaperons were very timely. Now if you could somehow get the inav devs to make the Mac os version work better, I'd have a inav fc in all my fixed wings.
Pawel is the Configurator dev, and I am guessing he just doesn't use Mac. The biggest thing people miss about iNav development is that the Devs do everything for free, so if it is something that they have time to do then they will, or if it is something that impacts them then they will. However if Pawel doesn't have a Mac then it would be hard to develop and test for it.
great video Lee very interesting too
I've used the inav logic switches on my FX-79 to allow the inboard flaps to mirror the elevons when in Manual mode, deploy and stay put (no- flaperon action) when flaps are deployed, and in stabilized modes they stay centered.
It has worked out well!
Have you shared the setup anywhere? If love to see..
This is awesome!.
:O Lost it, looking fw to see these LS things in action. Cheers.
Once I heard VTX power setting, I wanted it to do that exact thing that you mentioned right at the end. Change power levels based on distance from home position.
Video building on this one coming soon!
Inav sounds cool! Never used it before. Might try it out. Happy Flying everybody!
This sounds super useful, i would love to see a graphical integration of this feature, like you said, VTX power levels switching automatically when you get further aways sounds insane 😲
Yep, check out the video in the BrainDART playlist for a preview of the more advanced setup...
@@Painless360 i will 🙂
Hi Lee, given that you can change the vtx power dynamically using the bi-directional s.port function and base it on telemetry values e.g. gps distance you could also do this in OpenTX. I guess another example of multiple ways to do things. Be great when the logicals become more powerful. Keep up the great work ... Les.

Lee, this is fantastic info, and you have just solved a big problem for me! I am building a plane, but i really want to use Ardupilot for the flight control. That left me with a problem or two - how to remotely switch the recording on and off on my Runcam Hybrid, plus, how to change vtx power levels. The first i solved in a rather unusual way - i happened to have a spare Omnibus F4 Nano kicking around with nothing to do. So, i wondered if it would be possible to run it via sbus from the same rx that controls my main flight controller. I think sbus is a one way only signal - ie sends data from the rx to the flight controller without receiving anything back. So, in theory i could connect two different flight controllers to the same rx without issue. I done a lot of testing and discovered this does seem to be the case. So i have Ardupilot on my main f/c, and i have iNav on the second. Then i simply connected the Hybrid control wires to the iNav board and configured iNav to control my camera. I then used a free channel on my Taranis (that was not controlling anything on the Ardupilot f/c) and used that to control the camera via iNav.
Now this is where the info in this video comes in handy - i could not work out a way of controlling the vtx via Smart-Audio. I did come up with some wild idea of using a camera video switcher to switch my fpv signal to the video output on the iNav, then i would be able to access the Smart-Audio menu via the sticks, but that is not a good idea in flight, the plane being controlled via Ardupilot would be freaking out when i was moving the sticks for a start, plus of course i would lose my fpv video image. But i think you have just solved my problem! Use a spare channel and a spare 3 position switch on my Taranis, to switch the power levels via the iNav, all i would need to do is connect the Smart-Audio lead from the vtx to the correct output on the iNav controller. Thank you Lee, just the kind of info i needed. It is still a bit of a roundabout way of doing it, but until Ardupilot start to incorporate support for things like Smart-Audio and the Runcam control protocol it will have to do. Hopefully that sort of thing will come Ardupilot eventually. A bit like osd support, Ardupilot stayed well away from that for many years, until finally adding it over the last year or so.
Let's hope that the Ardupilot team get some of these ideas (and a few pieces of support for things like SmartAudio, TRAMP and CRSF) into the mix soon.. Best of luck with the build!
Yes, I agree. Paweł Spychalski is great RUclipsr!!!!
I like the idea of dynamic vtx power. It is efficient. I did try having a potentio knob to adjust the vtx power level up and down but they will just bump to the highest and lowest.
Yep, check out the video in the BrainDART playlist for a preview of the more advanced setup...
Thanks ~
Logic condition is available for servos. Wonder if it is available for motor mixer as well but hidden somewhere?
Certainly would be very useful for VTOL applications in which it is not uncommon that we need to switch some motors on and off during the flight transition.
love these wing videos Lee.im gonna have to try one one day.got plenty of tips from you.lol
Paul, I've become a convert to wings over the past year. The best way to fly FPV for a relaxing birds eye view IMHO..
@@Painless360 it seriously looks amazing Lee.as you say so relaxing and no panic of smashing something at 100mph.they are awsome
Hi Lee, thank you for the video. Is there a way to put a pit mode on a switch - so that it always starts in pit mode and can be switched to normal?
Painless I'm sorry for bothering you about this I figured it out all I had to do was change the 6th digit in the Global Function to the power setting I wanted to have as my lowest. In my case it would be 200mw which is number 2 then the middle power setting would be 600mw which is number 3 then the highest power setting would be 1w which is number 4. Thanks again
Great explanation, it's working brilliantly power switching on my Hifionrc VTX, I connected and configured it temporarily on UART3, but I use it on my Omnibus F4 and this one only has 3 UARTS on it, UART1 for CRSF receiver, UART6 for GPS and UART3 is occupied by the magnetometer SCL/TX3 and SDA/RX3. But my question is, can I use the SPI interface for the magnetometer, so I can use the UART3 for the VTX?
Changing power by distance, RSSI, or LQ was something I immediately thought of when I thought about what would I do with this. Another one I had thought of without seeing if there was a way as if the plane was in failsafe, set to loiter RTH and the battery goes below a certain value to force a landing attempt. Shouldn't need it very much as failsafe normally are distance and obstacle triggered and coming back towards home should recover command. BUT if there was a hard failure of the TX then I would want my wing to try to land at home instead of eventually floating off. Guess could do a slight bank with a little down elevator and have it circle down to earth but figuring out if you could do it would be interesting.
Thank you for all your help this last couple of weeks with my AR wing and setting up RTH and Loiter and the rest. But I have one more question on your videos. I have a problem with Angle, Horizon and manual. I have full range of my controls in Manual but in Angle and Horizon I get very little movement on the servos, I seen a video for how to change the throws but can't find it now ? Can you please let me know what video has to do with the settings on the wing . Thanks again for the help. John Duchi, JohnnyDRC
Google something like 'servo movement inav painless360' ;) happy flying!
Dynamic power adjustment would be amazing.
Lee so I started setting up the Logical Switches and I'm getting a Flag warning for the Mid setting under the Flags Column do you know why that would be. I started at 0=low 1=mid and 2=high. I soon has I click the save the circle under the Flags lights up.
That's normal...
Hi I have been looking at several of your videos and thanks for all the good information. I have a Radiomaster TX16s to control my planes and your videos has answered a lot of my questions.
I have installed a FRSKY S8R reiever w. stabilizer and smart port. the GPS is connected to the Smart port.
I do have a question around having the iNAV running on my TX16S. I see readings from the smart port FRSKY GPS installed but it would be nice if the Pilot View worked and the altitude and distance. Is it required with a flight controller installed in my plane?
I've never tried scripts like Yappu and INAV without having a flight controller installed. I'm guessing you're not a regular viewer as I did a video on something like that on Friday.. That video may help..
Hello! I love your channel! Quick question. I have an airplane with a folding wing. I put it on a switch, but want to set up another switch to enable that switch so I don't fold the wings in flight. Would a logical switch work for that application? Or is there a better way to do this. I tried special function, but overriding the switch just made the wings fold on the second switch. Appreciate any guidance you can provide. Thank you in advance for your advice.
Yep, logical switch is how I'd do it. Best of luck!
Hello. I'm using a Tbs Unify Pro VTX with a Matek F405 wing FC. With Smartaudio I'm attempting to control VTX power output. The new options on the Adjustments tab on INAV allow VTX power level Adjustment. I'm not having much luck. Watched plenty of videos but I'm stuck. Any vids you'd suggest I check out?
In INAV 2.6 this is all about to change so stay tuned!
@@Painless360 "Automatic video transmitter power change according to distance" That sounds promising! Thanks for the reply
Hello. Can you use this feature to run in paralel Digital & Analog FPV ? My design would be to use the DJI air unit for short/ medium range , and switch in flight to the Analog FPV when the DJI breaks up under 10-20 km range. But i don’t want them powered at the same time to avoid interference and battery consumption.
I'm not aware of a way to do that. If you figure it out, please let me know... Best of luck
Hi, is there anything special I need to do to use logic conditions? I am using INAV2.4 on a SPracingF3EVO and the logic condition GUI is just an empty table, cli commands "logic" and "gf" give me "unknown command"...
I've not used an F3 based FC for a while. I wonder if it's not supported on those older boards. I'd look in the wiki... Best of luck..
@@Painless360 Thank you for your reply. I could not find anything about limitations on F3 boards, but it may be time to upgrade. I pulled the board out of my parts bin to put it in a balance bot and the logic conditions would be very handy to switch the servo outputs off, if the bot exceeds a certain pitch limit.
INAV development is obviously interest driven, as it is freeware. Can you tell us about the interest in making it operational for boats with two engines (diff thr) for instance? Pavel made an airboat some time ago, but he also mentioned, that INAV onboard was not able to do RTH with only two axis' available. Is the intention to make INAV supersede Ardupilot and Ardurover in the long run? Do you know roughly how many people are working on this development?
Thank you for your great work, and the high enthusiasm from both you and Pavel :-)
I would like to see someone run a quad and a fixed wing on one tx. With two missions coordinated so you switch between manual and mission one chasing the other. Is this now possible? I'm going to figure it out if someone else doesn't. LMK!
Wouahou very interesting.
Are RSSI value and GPS params accessible with Logic Conditions (part of FlightParameters) ?. A mix of RSSI and distance from home to control Vtx Power could be interesting. ( Few years ago immersionRc in the Vortex with a Tramp Vtx had kind of a dynamic Vtx Power based on I don't know what, but without GPS. May be RSSI or equivalent ?)
Being able with these Logic conditions triggering Global function, if we can use real Time GPS value, would be great.
Many thanks for this new chapter, and yes sure I will be very interested to learn more with you.
Keep flying and doing all your great tutorials.
More on this type of setup coming soon. Stay tuned!
You should be able to do the power change by distance as 2.3 is setup I thought. Have you tried using the LC for "Flight" and "Home Distance (m)" ?
I am still flying 2.2.1 and using the Adjustments method to change VTX power in flight, I have a video posted about how to set it up.
That is the next video if there is a good response to this one... Stay tuned
Great, one problem that I had with 2 different vtx bought on smart audio 25,200,500,800mw it was that I changed power level when armed to "5" assuming 5 will be 800mw but I was wrong and looking by the led colours it told me that was 25mw, the way to be sure it's choose whatever and set in the osd 800mw and it will change to the proper value which in my case was "4"
Please see the notes in the video - SmartAudio only has three power levels settable via iNav (0,1,2 and 3)... That could have been part of the issue. Happy flying!
So I have a Mach 3 VTX and it has 4 power settings 25,200,600 and 1watt. In the video your vtx has 4 settings also but the way you set it up is the lowest power setting then the middle than the highest. so it looks like your switching from 25mw to 100mw then 200mw so how would you get to the 600mw power setting. I would like to go from 200 to 600 then to the 1 watt with the 3 position switch is that something that is possible? Thank you
You need to turn on the VTX stuff in the OSD using configurator so you can see the channel and power levels then change the power in the iNav OSD menu and see what iNav sees that power level as in the main iNav OSD (0-4 if you're SmartAudio).. Best of luck!
@@Painless360 I've done that it doesn't start with 0-4 it's 1-5 for Smartaudio in the Inav Configurator.
@@Painless360 So when you say the iNav OSD Menu are you talking about through your goggles or screen. Cause when I do that it comes up 25,200,500,800 and that's through the SmartAudio connection. The only place I see 1-5 is in the Configurator tab in iNav bottom left side.
It's an option in the things you can display in the OSD. You can show the band, channel and power you are using. Not all VTX units use the same iNav settings for each power level. Hope that helps..
@@Painless360 I have that turned on I've used it on other planes. I guess what I'm asking is if I have a VTX with 4 power settings that are 25,200,600,1000 how do I in the Logical Conditions make so I can select 200 for low 600 for middle and 1000 for high? Would I have to have a 4 position switch to do all power settings. Or is the way the Logical Conditions are set up right now you can only select the first 3 power settings of the VTX?
Is there anything comparable on other systems?
Not that I've seen. Other systems like Ardupilot has conditional functions and some smart stuff like automatic flaps...
@@Painless360 Many thanks for the reply!
please!!! do a video about mag interference coming from batteries. i have no problems with factory build lipos but when i use liion selfmade the compass goes crazy
Please see my build videos. Distance is your best friend or, if you can't physically separate the GPS and power system, then a piece of MuMetal can help shield the compass from stray EMF. Don't forget that you don't need the compass in a fixed wing iNav model...
Painless360 MuMetal, is that a trade name or something? I have a similar problem, some batteries are no issue, others seem to send the compass crazy, the compass and gps are 5-6 inches away from the frame on a stalk, so I think I need something more between the GPS/compass and the quad.
Google it and you'll find my video on it.. best of luck!
Painless360 will do and have just bought some (magnetic shielding) from RS as numeral is mega expensive, do you know which side the sticky part goes on (GPS or the mount) since they don't say - or does it not matter?
EnglishTurbines it's already six inches away (lol that sounded better in my head), maybe the compass is on its way out, it used to work fine.
Ah Pawel... The Renaissance man himself.
My brain hurts. 😁
Take two painless pills and see how you are in the morning... ;)
gf give me ###ERROR in iNav 2.6.1 gvar is there . .. I've got more reading to do.
This all changed in recent iNav releases... Updated video planned..
