This could happen if you used screws made for the Phantom 2 (they are longer) or did not re-insert the original motor screws when taking off your prop guards.I read the screws could Pierce motor wires.
I found cell phone towers to do that to mine, even brought it outta the sky once, signal lost 30ft away, boom bam got d____m!!!Could my summit prop gaurds be causing the problem. I read the screws could Pierce motor wires. I guess I'll take them off and see what happens, any suggestions? Thanks
