I've got a loosing signal problem, in phantom copter. I've previously put a topic on phantom pilots forum, regarding this. As my Phantom dealer told me, the problem is with signal receiver(it has 2 antennas) of phantom copter. I don't have much time to send this back to my dealer (heliguy,UK) and bring it back. I can buy a 2 antenna DJI phantom receiver online. - Could anyone please, guide me how to replace the signal receiver of phantom copter?
