Hello all, first post and I need a little help. I'm an electrician and run a small 3d printing business. I want to 3d print a frame and buy some 1000 kv motors and ESC's. But for the rest of the electronics and to keep costs low I would like to strip down and use the flight controller, reciever, transmitter, and battery from one of my cheapy drones laying around. I'd be using something along the likes of a UDI 818a. In the future then I can buy better parts and replace them to gain longer range/flight time. Is it possible? Thank you for your help.
