VMA-X240X - Wing Control Surfaces - Quad Flaps - What does it mean?

Question: What do you mean by Quad Flaps?

Answer: The VMAR Xtreme Stiks come with quad flaps in the wing. There are four control surfaces and each can be controlled by its own servo. There are two ailerons and two flaps.

Better Answer: Using a computer radio this four surface, four servo arrangment helps with XTREME aerobatics that the Xtreme Stik was designed for.

Normally, you would set up ailerons using two servos and the outboard control surfaces and you would set up flaps using two servos and the inboard control surfaces. With an appropriate computer radio, you can also configure the flaps as flaperons so that when flaps are deployed the ailerons act as flaps also. Spoilers and spoilerons (raised "flaps") are also possible using a computer radio.
