Hello fellow fliers. I would like kindly ask you to check my flight log. My issues are sudden fly aways, either in manual or automatic mode. All I can denote from the logs is, that at the point when fly away starts, quite high spike of vibration is introduced (@6:40) into frame . I am collecting ideas for improvement, before next airborne. Besides that, I am not satisfied with Acceleration Power Spectral Density profile, Actuator Controls FTT, GPS Jamming indicator, max speed (?)… Drone hovers & flies very steady. My HW setup is: S500 frame, NXP FMU-K66 on the halved kitchen sponge attached to a stock carbon plate with dumpers, Keesin 9450 carbon propellers, ESCs: 3 x ReadyToSky 40A OPTO, 1 x Rockamp Akia 40A / 2-4S Lipo / 3A BEC. BEC cable plugged into FMU (I shall remove BEC cable, but forgot to), no landing gear attached, 5200 mAh 3S LiPo… Thank you experts.
