Yes, I have the Illustrated Parts Catalogue, the plans for the aircraft - there are no control stops in the aileron system so the only rational explanation is that aileron travel is down to the travel of the yoke / control stick. There are primary stops in the *elevator* (actually a stabilator) fitted at the factory, and given that the flap is electrically operated, there is a microswitch within the actuator / servo which is moved to limit the travel of the flap... but nothing on the aileron control system, or rudder control system!
