RE: AR9000???
The default fail safe is on the throttle channel unles you:
Insert the bind plug
Power up and get fast flashing lights
Remove the bind plug
Make sure the controls are where you want them (gear up or whatever)
Power up the transmitter with the bind button, wait till you get solid lights.
Power everything off, turn on the transmitter, receiver, then turn the transmitter off and see if they do what you want.
