Let's not confuse a new guy. The term "flaperon" is used several places for different things.

The term "flaperon" is a combination of the words flap and aileron. In RC, what we generally mean is to use strip ailerons together as flaps. Normally this is done by selecting a Flaperon Wing Type in your computer radio and plugging dual aileron servos into 2 different channels on the receiver, the aileron channel (usually the right side) and the flap channel (usually channel 6 for the left side). This allows an internal mixing program to join the 2 channels to they may be used in opposite directions for ailerons and the same direction for flaps.

Activation of the flap function may be done by a knob or a switch or by setting another function in your radio which will give you flap movement in conjunction with the elevator similar to a control line stunt plane, stunt flaps.

If the flaps are set to move up instead of down with the knob or switch, you normally call them spoilers or spoilerons because they "spoil" lift as is done on full scale planes. You may also set the Flap knob in the middle so turning one way gives down flaps and turning the other way gives up spoilers. Spoilerons may also be coupled to the elevator, moving the same direction as the elevator. This setting is sometimes used on fun fly planes to assist in harriers and elevators.

So if someone says they have flaperons set, he may mean he is using a Flaperon Wing Type, or he is using ailerons for flaps with the Flap knob or Landing Switch, or he may mean he has stunt flaps set. I like to use the Flaperon Wing Type because it gives me individual adjustment of each aileron. I can set the neutral using Sub Trim for each side and also the individual end points. I hardly ever use the stunt flap setting for opposite direction flaps, but I do use Spoilerons on fun fly planes.
