UPDATE: My issues are resolved. What happened was I swapped out the white dampers that came pre-installed on the H3-3D with the softest dampers, the 40*. This was causing the gimbal to move too much, due to the soft rubber, and thus causing the flight controller to compensate too fast for the weight shift / vibration. landonkk pointed out that it could have been the difference in dampers. So I swapped out to the slightly stiffer dampers, the 50*'s, and also lowered the gains by 15% via Phantom Assistant per some info in this post http://www.phantompilots.com/viewtopic.php?f=19&t=10316&start=20 and now I'm in really great shape, and even with minimal GoPro rolling shutter ("jello"). Thanks everyone for the input! OP: Greetings all, I just joined this forum, looking to tap into some expertise! I previously had a P2 with the 2D gimbal, but sold it for a P2 with the 3D gimbal. I just received it a few days ago from Dronefly.com. However, I am noticing a crazy vibration / shaking in the craft. It is brand new, factory settings, never crashed. I have checked props for balance, and tried both sets of props that came with the craft. I am not sure what else I can try to fix the insane shaking. It does this in GPS, Attitude, and Manual modes. Firmware is up to date, compass has been calibrated, IMU has been calibrated. https://vimeo.com/93681876 password: drone Any input would be appreciated!
