Massive thanks to Pawel Spychalski and Painless360, without whose YT tutorials, I wouldn't have been able to get through this.
czcams.com/channels/mX3OXToMBKTppgRskDzpsw.html
czcams.com/channels/p1vASX-fg959vRc1xowqpw.html
Pawel's been posting recently about new features in the upcoming iNav 2.5 that should improve Acro flying over 2.4. It would be great to finish up this series with a 2.4 -> 2.5 upgrade tutorial and a review of the improvements.
what about chippies drone build ever
Totally, without the three of you i would have found this a much harder hobby to get into. Thank you very much indeed! BTW just had an idea, could the auto flaps feature be used to control the camera angle automatically too. Eg when the kwad slows the camera tilt drops to 5 and when at speed (say 20kph up) the tilt is increased to whatever...
I like Pawel.
He touches hot VTX.

Welcome to Poland 🤣
general shout out to all the people who posted tutorials and helpful beginners vids, wish you knew how much fun you started and continue to create, thanks guys, and zoe
Thanks Joshua, just pre ordered ZoeFPV's Microhawk kit and this is just what I needed right now as a primer. Thanks man.
I bought your flight controller and cannot wait for it to come and love the videos
Very helpful and informative video. Thanks Joshua.
We are learning something today!
I learnt something today, thanks Joshua.
Great tutorial, thanks a bunch.
For those who think the motors are still in the wrong position in Mixer, well... they are. But... by changing the negative and positive values, you're tricking the flight controller to do what you want it to do.
I *THINK* that's the case. @ 15:05, JB seems to confirm.
However... having said that... I found it quicker and easier to de-soLder and re-soLder the ESC.
This is awesome. I assumed motor remapping wasn’t possible and always moved signal wires. Thanks
Great video as always. BTW, looking forward to seeing your review for Radiomaster TX16S soon.
Thanks alot bro you really saved my day
Let me watch the part 1 first. Hey Joshua thank you for this video man is what I was looking for now I just need to know for yo wire a random esc with a random fc to pretty much cover all my fpv doubts
im going to try this inav thanks bro
This is great for my Tyro 129
Joshua you can just flip the board and move the motors with out desoldering anything. Just flip it and rebolt the motors to the proper arms, remount the fc. 15 minutes tops. I do like the video(s). Thank You
looks like you've read my post about Inav motor remapping theory (I used hexacopter mixer for quad copter to use S3, S4, S5, S6 pads for motors 1,2,3,4) Great, it's working!)
bardwell binge watching.. always good for the soul
I tried for days to figure out if this was possible when I built my 7" inav quad. I ended extending all the motor wires and rewiring. Now I know for next time. Thanks a lot for this info, awesome stuff.
nicely done
Literally waiting for this vid to drop😂
Same here bud
i couldn't wait and desoldered it
@@AnandNL I think that's actually quicker and a lot less hassle.
Thanks
Matek GPS on its way for first 7 inch build on which i want to use iNav. Hopefully the rest of your tutorial will be done by the time im ready to install it.
YES!!
I love that iNav series, as I also own a hexa which i'm rebuilding right now.. (need to find a good FC with enough UARTs and PWM outputs to drop autonomously a cat into neighbors pool! j/k)
Since when does it matter in what orientation the ESC is installed?
FC sure, there is a difference, but ESC? there are no sensors built in and only thing changing is probably the rotation :)
hello congratulations in your videos do not leave anything for granted .... I watched them all and this guide to Inav was the one I had been waiting for for some time. Just one thing, I built other drones but it never happened to me to have the motors in the wrong position, can't they be mounted well during construction? Only the verse can be wrong but I fix it with the esc software. Anyway I wait for your next video and the flight test with inav !!!!
Interesting, I think I would have re-soldered, save a brain ache. But a great tutorial how to do. I want to dip my toe into multi rotor, but want to use my own Radio. What’s a good one to start with?
Great video, Great series! Betaflight is best for drones, but INAV is ........ a very interesting platform :o). Good luck !
I put the esc upside down too... Took me a while to figure out what was wrong... Managed to fix it on the pc also lol
Or... You could spin the motors to find their positions, mark the signal wires on the esc connector, carefully remove them, and change their positions. It’s a bit annoying to remove the wires, but I had to do this for different brand esc/flight controller. I would expect this to work just for motor position changes if needed.
Yep it would work. I just hate doing it that way.
@@JoshuaBardwell For Betaflight it would be much easier to just remap the motors, but if I ever do an iNav build that requires I rotate the board, I'm going to be at least tempted to just move some wires on the connector.
Now in v2.6 we have the Mixer Wizard!
Remove all doubt and Remap the pin connector of the 4n1. Something that you might be doing anyway with mismatched brands of boards.
To me, this is easier than trying to reorder the plug. But it is easier with the plug to verify that you have done it correctly by raising the sliders. The plug is just such a hassle to reorder.
Also setting the "Number of motor poles" to match your motors seems to be pretty important.
The default is 14 but my motors have 12 poles.
And they were running louder and rougher when set to 14.
I could imagine not having this set right could reduce the performance and lifespan of your motors.
I was just wondering, if you have separate ESCs and you instal your FC rotated 180°. When you change the settings in iNav to tell it that you have rotated the FC, does it automatically work out that the ESC pads are also 180° out of alignment and in so doing have the motors in the right order. Hope that was clear enough question. 🤦🏼♂️
So what should the ESC look like if it was installed the way the manufacturer wanted?
I'm glad you have done a series of videos on INAV.
My question is; if my FC had settings (maybe some are default) in BetaFlight and I flash that that same FC with INAV, does any settings stay on the board such as default settings etc?
I was curious to know if any settings carry over when converting a FC from BetaFlight to INAV.
Is any of CLI data from BetaFlight usable in INAV?
Thanks!
I would say no.
Easier to change the order of the esc wires or repin the wire is what I did ... that way I never have to worry about it
Interestingly, this (changing the mixer rules to remap motors 34) did not work; even after saving the changes and rebooting. Is this ESC dependent? PS: Using INAV 2.4. Looks like I have to rewire!
PS: I also tried inverting the number after "mmix" command - no dice!
I'm building a 9" quad for Inav and gps flying (Inav only has 3" to 7" presets). It goes into a violent oscillating shake then crashes after a few seconds. I'm thinking it's in the PIDs setup. What would be a good starting point? Anything I could be missing?
Hi there, I just flashed iNav 7 on my first quad. Does this still apply for this version of iNav, or they fixed this issue and there is a way now to tell iNav which motor is which?
Trying to tune drone I put iNAV in. Now on 6S gets flutters. Especially with li-ion. So far I got it to hover fine but anymore throttle and flutters. Also upped the filters
I think Inav 2.6 allows the remapping now. they really need some UI help its a bit of a mess.
I built the Tyro119 and flies ok on betaf;light. I set up iiNAV{for GPS etc} and had to change the mixer, like you did. When I arm the quad, no motor.In iNAV everything seems ok.Need help
Is the mamba f4 stacks still considered good, I am a beginner and building my first quad and purchased it.
Yep definetly
Doing it from the cli is faster and avoids potential errors. You just need to invert the number after "mmix"
Ummm. I hate to say this but you are right. It's just been so long since I did this that I forgot the CLI and got distracted by the GUI.
Joshua please! I freakin love all your videos but this last song almost makes me cry cuz video ends :) Please! Think about change it for something more happy ;D Thanks a lot for all your job that you'v made... I defenitely learned a lot :)
So I'm running eachine wizard drone ESCs with omnibus f4 v3.1 I have set oneshot125 protocol but there is no signal going to my ESCs and there are just those 3 beeps can u help?
You certainly not need resource remapping to avoid the hassle... It can be done in the configurator. But as betaflight is complex to keep some extra flexibility, INAV does the same here, allowing one to have a lot of hex one weird configurations doing the setup you did.
However, they could add a setting to do a "motor swap" in the configurator, It requires a Feature request in github, and someone willing to implement it.
I do think that the ability to swap around the mixer lines in configurator would be nice. But of course, it takes time and effort to build it.
A great series Josh. So far so good, but my barometer symbol is red, not blue. The blue light on the FC is flashing madly, and this doesn’t look like your experience. Any quick thoughts on the cause?
Plug in the battery then plug in USB then see if the baro goes blue. Sometimes the baro is not powered off of USB? Not sure exactly.
I can not get iNav to set to anything but Standard ESC. I am running a Brain Radix with a T-Motor F55a 4in1 on the latest BLHeli_32 firmware. I tried all DShot settings (150, 300, 600) and when I click 'Save and Reboot' it reverts to Standard. It will stay on multishot but the esc's start up out of sync.. I did try the motors in the Outputs tab and each spins as they should and match up appropriately in the correct motor order. Any idea why it would do that?
Sighhhhhhhhhhhh. I feel you.
Joshua 15% is way to high my 7inch in acro would not come down without going into a dive.
Work with Mamba F405 ????
Hey Josh! My question is not regarding to this build but I was thinking thi will be the shoretest way to get in contact whit you! I got a 2" little micro and I got the problem that when I punch the throttle the screen goes black and comes back again. It's an F3 bord in a GT90 and I changed the factory defaults actually some of them. I changed the pid loop freq from 2 and 1 to 4 and 4 and I had oneshot 42 and I changed to 125 could the couse one of these or these 2 together thiss problem? Thank you advanced! And I wish you a beautiful day! And happy flight ;)
Usually the problem you're describing means the voltage regulator that powers the camera is browning out under load. If the camera can take vBat voltage, you can move the power from 5v to vbat as a temporary solution.
@@JoshuaBardwell thank you very much! Your answers always help me out form situations like this! I appreciate it see you in the next live and also on your patrion 😁
thanks for video! How to reverse motors in Inav?
You reverse the motors in blheli or by re-soldering the motor wires.
@@JoshuaBardwell i mean : how inav understand that )) PS: set yaw_motor_direction = -1 like in old times )) thank you!
Ive just set my quad up for Inav , The motors position is correct , However the motor spin direction is revered, In Betaflight theres a motor reverse direction tab, so its easy to correct the motor spin , However i cant find a way to do the same in Inav .... Any clues ? Thanks
That setting does not reverse the motors. It tells the FC that you reversed the motors.
Use blhelisuite to reverse the motor or swap any 2 motor wires.
Are you going to add a compass to the build so you can use the GPS features in INAV?
Yes. czcams.com/video/WYPzt-HcGH8/video.html
@@st200ol the GPS in the kit has no compass.
@@chriswhitehead6095 I didn't know GPS worked without a compass, today I learnt something. :-) I suspect a compass wouldn't work too well on something so small anyway, probably too much magnetic interference.
st200ol For some GPS functionality (like RTH) there must be a compass available, otherwise it won’t work
The motor idle could be set at 15% because they may think most people maybe using Inav for RC Planes if so 15% would be about right. As for rearranging the motors wow that looked so strange & difficult ( Think I have got lazy with betaflight ) Great info JB
For most fixed wings the motors are disabled at zero throttle. That way you don’t cut your fingers off when you throw it to launch.
@@brandonbell359 I did not mean the small stuff that you hand launch. I'm meant a model with landing gear that uses a runway of sorts.
@@GeorgeCooper_LoneWolf Maybe. I think I'd still prefer to be able to stop the motors. If I needed to "idle" the plane either taxiing or landing or whatever, I'd manage the throttle myself. If I were to guess at the high idle, I'd say that it was more aimed at long range quads. Swinging a big prop slowly is a pretty efficient way of flying a quad, but the resistance of a big prop at low rpm would be tough on the motors. You'd want a high idle to keep the motors from desyncing and dropping the quad.
@@brandonbell359 You would have a kill switch to stop the motors / Arm Switch. As for the 15% only Inav really know why But I do no a big long range quad wont fly at 15% idle.
@@GeorgeCooper_LoneWolf As someone who has disarmed in flight, I can tell you its not a very comfortable experience. Also, its not for flying at idle. Its for keeping the motors spinning so you have control authority while descending. Turn your idle down, get some altitude and drop the throttle on one of your quads and see how stable the decent is.
Or remap the wires in the plug.
That was my comment also. Since this video is meant for beginners it should be pointed out that not all 4n1 connectors have the same pinout and should be verified. That was my case, different brands. I had to switch pins anyway, not a big deal. This is good to know that is possible to do.
16:40 all of his motors are spinning in the correct direction, what should I do if two of mine (positions 1 and 4) are spinning backward? I don't want to resolder
czcams.com/video/45eS9mok6is/video.html
I believe iNav doesn't have runaway protection/anti-taz. I've had a couple of nasty life threatening runaways.
The default profile for mini quads explicitly mentions a size range of 3" to 7", but what if you are building a quad that is bigger or smaller? I'd assume that going outside of this range a little (2" / 8") would be fine but what if you had a much bigger quad (10" / 12") - What has to be changed specifically for this size of quad? I'm assuming it's related to the navigational PIDs?
iNAV offers many presets. Lots more than shown on the first connect after flashing. The preset section has settings for 5" (race, performance, gps), 7" (endurance, freestyle), 10" general purpose, 12" general purpose, 280mm tricopter, 600mm tricopter, airplane general, 600mm flying wing and a few special wings as well.
@@_seriousrob_ Ah I didn't realise there was more. Thank you!
@@yngndrw. I think JB will go through the tabs in later videos, so you couldn't see it yet.
Hey Josh, I still love your vids! Really! Every single one! But I wish to have more information in a 17 minutes video. I think the content you presented here could easily fit in 5 minutes... what do you think? ;-)
If I thought this information would fit in five minutes, the video would be five minutes long. There is a lot of very basic info in this video that beginners need to hear, but experienced people already know it. If you cut the video down to 5 minutes, beginners will be confused and left behind.
Ok of course you're right, sorry I was so excited about the next step in inav config and can't wait to get to the "real tricky" things... 😉
Thank you four your great work! 👍
INAV's the dogs
Hey Josh, I got this far but my one motor does not seem to get full power when I move the slider. All others seem fine but my position 3 motor is the one having issues. Suggestions?
If the motor doesn't spin at all when you raise the slider then check your soldering. If the soldering looks good swap the motor to another one. If that one doesn't spin then replace the ESC.
@@JoshuaBardwell got back from vacation, resoldered one wire and it seems to be all fixed :)
That is all fine and dandy that all your motors are rotating in the proper direction, but one of mine is rotating in the wrong direction. What about me?
Use blheli to reverse the motor or swap any 2 of the 3 motor wires with each other where they solder to the ESC.
This shoukd be one of the steps in the tutorial (I hope).
Just ordered the Tyro 119, unfortunately I just received the shipping information. They are sending it "ocean shipping" in just 2 short months I should be able to do this build. Be wary when ordering from Banggoods, it will be some time before you receive your order.
I'm not sure what the current situation is with shipping, but I do know things are messed up with air cargo due to coronavirus affecting air travel. A lot of cargo goes on passenger planes, but a lot fewer planes are flying now. I think probably one of the more expensive shipping options would have come faster, but I can't say that for sure.
Maybe I missed this, but will inav work with any flight controller?
It works with many but not any. Check the github page: github.com/iNavFlight/inav/tree/master/src/main/target All Targets are in there.
@@_seriousrob_ thanks
The best case will be if the FC has barometer on board and SDA/SCL pads for a compass.
Hi Joshua, thanks for all the great videos. I comment on this video because my question is most related to this one. I am using Betaflight though. Should be the same wrt the mixer. I have known this for a long time but was always too lazy to follow it up, but while tuning my newly built quad, I figured that the mixer may not be optimal. The frame is not a true X. I used www.iforce2d.net/mixercalc to calculate the actual motor mixer values. I came up with
mixer custom
mmix reset
mmix 0 1 -1 0.8 -1
mmix 1 1 -1 -0.8 1
mmix 2 1 1 0.8 1
mmix 3 1 1 -0.8 -1
I did not fly the new mix yet, but from your experience, how much of a significance does it have (in general).
I found only my tiny whoops are true X while my 3 and 5-inch quads are all stretch X.
Thanks in advance for any suggestions
I thought like how would you make such mistake and it happend to me 😂
first.
so this is not ideal setup the f4 controller and gps device you use so thats why it fail, i watched the whole video though
Instead of taking a screenshot of the settings at 10:00 just type the values into Excel... it's just a 4x4 matrix, it wont take that long. Then you can rearrange the rows into the correct positions in Excel, and copy the values into the configurator without the need for mental-gymnastics, and you won't make any mistakes!
The lack of resource remapping in iNav is not about space on the board, but about user friendliness or implementation complexity, according to this github issue, but I don't lose faith that maybe someday someone implements it. github.com/iNavFlight/inav/issues/1145
DON'T plug POWER into the quadcopter while it is plugged in. Just burnt the SECOND FC I had purchased to replace the first. I don't have another 80 bucks to spent, Bardwell. Will not be following the rest of this tutorial.
I don't know what's going wrong but plugging battery in while usb is plugged in should not fry anything. I think you have a wiring mistake.
