I had a second party install goggles kit so i could see where my phantom was going. After hooking up power to the camera he wanted to make sure it ran. He didn't know what he was doing and turned it on in his shop. It took off in his shop and crashed and snapped one of the blades. I replaced the blades and turned it on and all of the motors are running backwards now. It just pushes itself to the ground. The camera installer claims he never undid and of the original wires. Any suggestions?
