(Phantom 2 non vision with H3-2D gimbal and Gopro 3) - Yesterday, while attempting to take some aerial video the Gimbal started shaking randomly. I thought it may be the props or the rubber absorbing balls so changed both, which did not fix it. after trying a recalibration of the Phantom 2 controls and compass the problem still exists. I took the gimbal off and tested the Phantom 2 and it flys without shaking. Putting the gimbal back on it will randomly shake, then stop then shake again. Any suggestions on what should be look at?
