I crashed my drone. It came down on it's side and buckled one of the arms. I think my insurance will replace it with a new one, but I would like to fix this one for a spare backup one if possible. What is involved with replacing the upper and lower shell halves of the Phantom 4 Pro? What else is likely to be damaged once I get into it? I consider myself a fairly capable do-it-yourselfer but are things epoxied together once inside or are special tools needed? Also, where is the best place to buy the parts?
