Most commercial and private pilots who get into RC, call RC a "humbling" experience.

Things tend to go fine as the plane moves away, but the second they turn the plane around reality sets in.

Back to the topic at hand.

I assume you purchased the 72mhz version, correct?

If so, remove the crystal from both the TX and RX ( don't confuse the two, and re-insert to assure a good electrical connection.

Then disconnect the ailerons and check the rudder and elevator servo.

You want to eliminate the possibility of a stalled or stripped servo. I received one plane where the rudder servo worked for a few minutes then seemed to have stripped because of a poor factory installation.

At worst try one servo at a time on it's respective channel to verify that the receiver is working and that the signals are getting to each channel.

Also try ARMing the ESC, by taking the throttle up ( restrain the plane! ) and back down, then set the trim on the throttle all the way down. This should arm the throttle if it does not come on armed.
