Building a 4 star. Before I start installing the servos, etc. want to check things out since I have a new Airtronics RDS 8000 radio. I have a Racers Edge 1600 NiMH battery, a normal switch, the 92824 receiver (2.4ghz) and Futaba S3004 servos. I have binded the receiver and transmitter properly, I believe but the servos don't move. Any suggestions?
