Hey all, im helping out a friend who is building his quad. Running a a Lux FC, with a spm 4648 receiver and trying to bind to a DX8 v2. we had it bound last night and while setting mid point and end points we changed the model on the Radio and the receiver went dark. Now we cant bind, and we dont get a bind light... its almost like the receiver shorted out or locked up? We have the FC bridged so that its putting out 3.3 v... any other ideas???
