im new to the drone world. I got a phantom 3 for a $150 used when I bought it I was told what problems it had which was something with the motor on the camera and something with the compass and the guy I got it off of flew it right in front of me and I also flew it and everything he left and I flew it some more crashed it 3 times nothing major though and then that night I wanted to fly it at dark so I did and for got one small step and that was to put the antennas up so it took off on me and crashed hard enough to throw the battery out of it... so I figured I would try to fly it again the drone turned on and would do everything but fly it was like the controller wasn't connecting to the drone... so I boxed it up and started buying Misc. parts for it I bought a new shell landing gear camera motor wire set screw set gimbal blades blade guards gimbal guard I bought like $300 worth of parts for it. I stripped it down to basically nothin to replace the shell and found some wires that were cut so I replaced them with me wires ran into a problem when I got to the antennas in the legs couldn't figure out how to hook them back up finally figured that part out and finally I got it to where I could at least turn the drone on meaning I didn't put all the screws in the body just in case I had to take it back apart.. so I tried it out the drone turns on and everything but it will not fly!!!???? I don't know what's going on with it maybe I'm not quite sure on how to get the motors to start up but it is doing the same thing that it did right after I crashed it but now it has new parts on it...??? Any ideas would be greatly appreciated or tips on where to look or what to replace next... I really want to fly it bad but I can't figure it out!!!! Thanks in advance!!
