I am in the final stages of tuning a heavy lift octoquad and I am running into an issue with the roll axis that appears and disappears seemingly at random. The roll axis will respond very slowly to my inputs, almost like the sensitivity was turned way down. And the copter will be very slow to return to level after being rolled in either direction. This behavior only occurs on the roll axis, and appears and disappears seemingly at random. So one second everything is fine and the next second I have restricted ability to control the quad on the roll axis. Pitch and yaw are unaffected.
This following issue may offer a clue to the roll axis problems but I’m not sure. During the autotune process the copter rocks back and forth diagonally when autotuning the pitch and role axis’s. I turned down the autotune aggressiveness from .1 to .05 progressively and the behavior still persists at .05.
Not sure if the 2 issues are related or independent. If anyone has any idea what may be causing the strange roll behavior please let me know, I’m a few hours deep into forums and I have not found a similar issue where it appears and disappears at random.
