Just installed the gimbal on the P2 and everything seemed fine at first. Testing checked out/pitch was OK. Tried to test fly it and the gimbal just flopped there as if it didn't get power. But the GoPro was charging. I tried rebooting the aircraft, removing the battery, but nothing worked. I hooked back up to the P2 assistant software and saw that the gimbal was OFF. I turned it ON and it responded. But now it still intermittently does not power up when turning on the aircraft. It even tried to hammer the GoPro to death a couple of times by spontaneously rolling back and forth to its limit stops at high speed like a crazed woodpecker. Anybody else seen this behavior?
