Well, I checked both crystals and there seems to be good contact. I moved the TX about 10-feet away, partially extended the antenna and turned it on. I then connected the battery to the plane and got the same results:

1. Loud buzz (not grinding) from both aileron servos. Buzz becomes more subdued, then stops. During this time, both elevator and rudder servos work properly. Stick movement results in a soft buzz from the correct aileron servo, but the shafts do not move. I've checked for anything that could be binding or restricting them, and found nothing.

2. After about 10-seconds, the rudder and elevator servos start moving back and forth on their own (constantly and quickly), and moving the rudder and elevator controls on the TX has no effect on this.

3. I turned the TX off, but left the plane connected to its battery. Interestingly, the rudder and elevator servos continue to move, but at a much slower rate...perhaps every 15 to 20-seconds or so.

I've got the motors disconnected (haven't installed the props yet) till I get the problem figured out. During my initial test, both motors turned on and off randomly and erratically, and did not respond to the TX.

Sorry to be a pain, and thanks for your help.
