so what would I need to convert a p1 to a fc40? I bought some used drones at a pawn shop, 2 for 500. a pv2+ and a p1. one with the upgraded controller, and a standard one on the other. I had a cracked antenna that I fixed with a 5 dollar digikey part for the gps lock on problem. What would I need to convert the p1 to a fc40? or what do I need to add other then the camera?
