Our copter suddenly oscillate hard on nick during a fast flight. What is happened here?
Fast Flight Begins -> YAW drift slowly (Pilot corrected it) -> Copter oscillated on Pitch ( like a Hard Braking Manouver) for 5 seconds until it hovers normal - than bring it slowly and carefully back and yaw twitches a couple of times 10 degrees.
EKF IMU Ground Mag Anomaly and EKF Glitch if the flight began… mhh… VERY STRANGE
Maybe it has to do with the compass inconsistent ?
FLIGHT MODE: ALTHOLD
Hard acceleration (higher current) -> compass inconsistent during higher current (GPS and Compass dont fly in the same direction -> EKF Glitch was detected through different direction (current related)-> and then ekf kicked in and a short movement going through the copter and it has began to oscillate because of that.
Sound that possible?
HERE IS THE LOG :
