Pilots, looking for some advice on the best course of action. Flying my relatively new Q500+ yesterday. I was about half way through a large radius Watch Me circle at low speed when the Q500 tumbled from the sky. The circle I was flying was half over freshly mowed field and half over heavy gravel roadbed under construction. You can guess which surface I was over when I had an unplanned landing from 125'. I thought to kill the motors on the way down, but I don't think they had time to stop spinning since all props shattered on impact. All, that is, but the one that fluttered to earth not far from the crash site. As part of pre-flight ritual, I install all props & then triple-check each of them for tightness. I have no idea how this happened considering the motors spin opposite the thread direction & there was only a small side load & no downward load at the time. Wind speed was almost dead calm. My immediate concern is finding the quickest & most cost-effective path back to flying. The Q500 has a number of cracks in the bottom of the airframe. The top is badly scratched but the damage on the top is all cosmetic. The battery door clip is broken, but the battery stayed inside & wasn't damaged. Motor #1 has a bit of an angle coming out of the airframe and there are some plastic scuff marks where it rubbed against the frame. Motor 4, which is the one that lost the prop, has some chewed up threads. I plugged it into the GUI, all systems checkout out & all ESCs tested "green". The CG02+ camera has a crack in its cover that doesn't look too serious. The rear arm of the gimbal yoke is bent, but may be salvageable. One of the leads on the camera cable was yanked out. One of the tracks on the mounting plate broke off. So, what do I do? Send it back to Yunnec or buy parts & put it back together myself? I was able to find all the parts I think I need for the Q500. I can't find just the gimbal yoke anywhere. If the only option there is to replace the whole gimbal, straightening the original may be an option. So, cost & turnaround, Yuneec professional techs doing the job right. What would you do?
