After a crash that ruined my previous H3-3D, I installed a replacement. It's the newer one that has a cable plug to the gopro and interference board. Flown it twice so far.....but when flying, the camera/gimbal occasionally & randomly jerks left (20-30 degrees!).....making good video and good piloting very difficult. Any suggestions? Do ones to recalibrate something? Thanks in advance for your help!
