Thanks David, The manual doesn't talk about pairing, I think they are just paired pre-purchase. I actually bought the second of these drone & controller recently to see if I can diagnose whether it is the drone or controller that was malfunctioning in the first one I bought. Thought I'd try pairing the new controller with old drone and if that solved the problem then the issue was with the old controller, not the drone and visa-versa. Not sure about the "usual way" of pairing, I just get no response other than the controller message 'Connecting' but it never does (even using the STOP-Power option. I'll try a few combinations though in the morning.
Cheers, Neil
