You talk of a hard right roll with the loss of control. When you initially turn your model on does the right aileron go up, or maybe the left aileron go down, or one of the elevators do the same as stated above? Or do all the control surfaces sit at neutral until the link is made?

If any of the control surfaces move to some crazy position, you will need to rebind the system to change this. Once you complete a plane setup you should always rebind to ensure everything is centered and straight in the event of a power failure/loos during flight. This is called the smart safe/fail safe setting.
