The stabs control pitch. They also control roll in conjunction with the flaperons as necessary by the flight control computer.

As you found the aircraft has flaperons. Flaps are controlled by the gear handle and are one setting. Gear down flaps down, gear up flaps up.

Leading edge flaps continuously operate in flight below supersonic speeds between 2 degrees up and 25 degrees down. They are active when the nose gear is off the ground and operation is triggered by the nose weight on wheel switch.

That enough for you Fender?
