Computer radios can do all sorts of things. Flaperons is one of the ones best avoided for beginners. Yes, you can do it , but for most of us it is best avoided as it tends to create a plane that becomes less stable and wants to rock and roll all over the place.

On most models the flaps are near the fuselage and the ailerons at the outer end of the wing. With flaperons, the whole length of the moving surface becomes aileron and flap and big flaps are generally not good for stability.

A friend has a model of a Pilatus PC-9 which is an advanced trainer used by the Royal Australian Air Forcel. He did not build the model. The real aeroplane has flaps but the model has been built without them though they are an option on the plan. He tried using flaperons to slow this slippery model down but it just turned a nice flying model into an evil handling monster. He has abandoned that idea and is now about to embark on building a completely new model from the same Airborne plans and this time he is going to incorporate flaps and retracts.

Now Elevons is a good one which you can use on flying wing type planes like the Me-163. In this case, the two movable surfaces on the back of the wing do double duty as elevators (moving up and down together) and ailerons (moving opposite each other). This also needs two aileron servos.
