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.

Installing the flaperon on the glider's wing.
https://en.wikipedia.org/wiki/Flaperon
It's a full-span flaperon, in two halves. Each half is almost 12 feet long.
Each flaperon half has 8 hinges made of a pintle/gudgeon pair. (1st photo)

When installing the outer flaperon half, I also have to engage two sets of pin/sockets that ensure the two halves move as one unit. (2nd photo) (Each flaperon half is driven by its own flight control linkage, not shown here.)
One of the 8 hinges on each flaperon half also serves as a retainer that handles side loads. (3rd and 4th photos.)
The flaperon halves are intentionally not very stiff longitudinally so that they flex with the wing, but they are much stiffer radially to resist deformation because they are driven at only one point by the flight control linkage. This feature is fairly easy to achieve in composite fabrication because you can orient the fabric fibers in certain directions. In this case we used Kevlar, not carbon or fiberglass.)
