So I've had the P4 for only 3 days and I've already managed to crash it. It flew without incident the first 2 km, then on its flight today, of no more than 5 metres, an unexpectedly strong gust of wind came up when the drone was at an altitude of about 2.5 metres, and it collided into a wooden post. Two pieces of white plastic near the top of the landing gear popped off, and the battery came clean out. Then it landed onto grass. At first I thought the worst, but the plastic snaps back in (albeit not quite as flush with the rest of the landing gear as it used to be). The camera also still records and transmits data. However the gimbal is now limp. It doesn't even move when I power on the P4 (it did when I first powered it on after the crash, but hasn't for a while now). It also doesn't respond to RC controls in the slightest. It doesn't make any strange noises, it just simply hangs there and does nothing except transmit video. I'm just wondering what is the best course of action from now? I have tried such things as gimbal calibration, but to no avail. Does anyone have any helpful suggestions about what I could possibly do before seeking professional repair?
