RE: Bob Cat Copy Falcon 120 Jet
Cody,
I suspect you have the flap servos Y'd from the flap channel on the receiver with one of the Hitec's reversed with a programmer. As Tim says a stalled servo or one that is working extra hard, can cause funny things to happen. If you have your servo arms set so the arm is 90deg to the flap hinge line when full down there would be no strain on the servo motor, but anywhere in-between the strain will be on the motor. I lost a Bobcat because a small servo on the retract valve went bad and caused a heavy drain on the receiver battery. The elevator servo went to full down and pan caked it into the runway. Fortunately your elevator servo recovers before it causes a crash. Whether you have one or two batteries you're usually limited by the switch or other small connections. If you haven't done so, be sure to check all connections even swapping out the Y.
