elevons
Aircraft control surfaces combining the effect of ailerons and elevators. Normally, these are used on delta and swept-back wing platforms and are located near the wing tips. The fore-and-aft movement of the control column causes the elevons to operate together, which in turn rotates the aircraft about its lateral, or pitch, axis. If the control column is moved sideways, the elevons move differentially (i.e., one elevon goes up while the other goes down), causing the aircraft to rotate about its longitudinal, or roll, axis.

The control surfaces, in this case trailing edge elevons, were designed to snap fit onto two hinges that protruded from the outer wing section.
The wing end fences also provide a degree of yaw stability and serve as a retaining structure for the elevons.
