Dear friends,
I have similar story as you... I got P3A with old motors on Christmas (in store in czech republic they have probably full stock of models with older motors and still are selling it), I did FW update from old ver to v1.4 and then directly to 1.6. First two days P3A was flying good. Outside temp was 10degC. Next days I started to observe strong vibrations. Only one change which happened was outside temp going down to 3 degC.
I made several tests to be able describe more the behaviour of aircraft to DJI tech support. First I did calibration of IMU. Aircraft was standing on floor stone with level (measured with water level tool). Everytime when I started motors on the ground still before take off the aircraft started fidget / wiggle with body. It was mainly represented as shaking of arms with motors with visible deflection of arm about 1cm from its axis. I tried to record it on camera in my mobile phone but vibrations seemed with higher frequency so couldn't be properly recorded and seen on video, sometimes vibrations were visible as apparent unreal frequency difference. When hovering after some time the vibrations have been decreasing but still major and visible. When I set Yaw gain in app to 80% the vibrations little bit decreased but still are there. In flight video, even there is stabilization with gimbal, there is very very small horizontal shaking of image which makes it unpleasant to watch.
Last day I tried to compare flight outside with temp 3deC and inside building without GPS signal and with 20degC ambient temp. Ouside vibrations, inside building placid flight....
With agreement of DJI tech support I sent it to warranty repair via my local store I have bought from...
Kind Regards
Viktor, Czech Republic
