This video shows the flapperons moving as camber-changing flaps. The two control surfaces move in unison. My flap control system has five settings. The central setting is flaps zero or flaps neutral. Two settings increase the camber more, which is suitable for low speed flight. Two settings decrease camber... this is when the two flapperons move upwards.... and this is suitable for higher speed flight.

Adjusting the flaperons.

This video shows them operating as ailerons. I move the control stick side to side.

Note that at max deflection, the control surface moves above neutral position more than it moves below neutral position. This is the principle of differential ailerons. It helps reduce adverse yaw.

The first comment to this toot will be a video showing the motion of the flaperons as camber changing flaps.
