Looking for some help here. Just got the electronics installed in my RC12R5.1 and I can't get anything to happen. Everything is brand new. Futaba 4PL radio, Futaba R2104GF receiver, LRP flow esc, LRP 13.5 motor, and Reedy battery. I know the radio works because I use it with my RC10B4.1. Trying to set the receiver to the radio, but I get nothing. I know I am overlooking something.
