Hello, I am new to this forum as well as new to UAV's. I have a new P2 H3-3D with the most recent firmware updates. I am using Mac... When going through the powering up sequence, the gimbal motor to the left of the gopro hits the ground a couple of times and jerks left/right up/down almost violently. Then the camera/gimbal stabilizes. When in flight, if I go from a hover to a rotation to the left or right, the camera becomes not level, until I rotate the P2 the opposite direction, at which point it levels again. It does not stay level during fight! The gimbal also makes a very wienie noise when going through those motions. I have handheld gimbals and have little experience balancing those, but I am not sure what the proper procedure is to balance the H3-3D. If anyone has any suggestions, I would greatly appreciate the insight! Also, I noticed on the DJI support page for the P2, that there is an H3-3D assistant but only for windows. Is this something that I need to install on a PC to help configure the H3-3D or does the Mac RC and P2 assistant accomplish the same thing? Thanks for your time!!!
