Nice to see the the process of analizing Inav blackbox data! Find it very usefull. Strugeling myself with twitchy gps 3D lock in comparison to good angle mode. (Y6 Inav) 👍 keep up the good work
Hey Pawel, at 4:23 you mention that the vertical position is calculated with reference to Barometer, GPS, and Accelerometer. I thought the GPS Altitude was only used in Fixed Wings, is that not correct? Multi rotors are able to use GPS Altitude to help stabilize z-axis movements?
Had something similar on a Tricopter with 8" props a year or so ago. Was using a RC Explorer tricopter frame flight controller, where the actual FC is the frame, holding the arms together. So any vibrations from motor / arms, goes straight into the accelerometers.. couldn't get rid of vibrations, and had really poor alt-hold.... Soft mounting motors helped a little, but still not enough. finally solved it by having a separate flight controller, mounted on some stand-offs... Alt-hold immediately became perfect....
Excellent to stress the correct & precise balance of the propellers. Unfortunately the words "correctly" or "properly" are ambiguous. Thus, a companion video on the art of precision propeller balancing (and how to analyze & what to look for) is needed here, please. :-) Also, the art of CG balancing, too.
Can you make a video on trouble shooting pids and vbrations on larger quads. I own a f450 that is very wobbly under the 450 class inav preset. Even tried the other and still no luck. Motors and props are balanced but frame is a little wobbly. Any chance I can filter it out? I am using a matek f405 AIO (no yaw twitches).
Tuning on big multirotors is somehow different than small ones. Push roll and pitch P until it will become locked in. My 600mm requires around 11-12 on P to fly good.
interesting video - I will check if its useful when analysing fixed wing control problems
thanks Pawel - keep them coming
regards
Hans

Good advice Paweł. Thanks mate!

Realy usefull vids.Thank you!
Balance the Props and Motor Bells ......makes big difference

any filtering settings?
