Don't flame me for asking this .....but what do the elevons control?

[snopercod]

Elevons are like "flaps" on the trailing edge of the wings. They move up and down and provide pitch and roll control. There is also a body flap in the center for pitch trim. Take a good look at a shuttle picture and you will see them. They are split in two parts for structural reasons: Inboard and Outboard.

Ailerons control lift!

[Rifleman]

Pitch and roll. They combine the functions of elevators (pitch control) and alerons (roll control). Move 'em together, they control pitch, move them in oposite directions and they roll the aircraft.
