I need some help from the group.
I upgraded two drones to 1.16.1. One of them flew well after calibration, but the other was almost uncontrollable in roll. I took it off in POSITION mode. When I gave it some forward motion it immediately started swinging back and forth violently in roll. I took my fingers off the sticks and in a few seconds it calmed down. I tried moving it to the left, and again it started to oscillate in roll. Just about any movement caused the roll oscillation. I landed it and recalibrated. Same problem as before.
Flight log for the bad drone. Tarot X-6
Flight log for the good drone: F550
Looking at the actuator controls and the FFTs it is evident that the two drones behave very differently with the same version of PX4. This has not happened with previous versions. It looks like the Tarot X-6 needs some parameter changes. What has to be changed?
Thanks for any help.
Joe
