What you have is essentially "Pop-Up" Spoilerons...should make your WALLS and PARACHUTES quite spectacular.

FLAPERONS - Ailerons that also function as flaps...they deploy down. Each aileron must have its own servo to do this. Usually part of the setup with a computer radio. Can be used to slow landing speed or give more lift for take-off. Usually tied to a switch or knob.

SPOILERONS - Ailerons that also functions as Spoilers...they deploy up. Usually a mix with Elevator to tighten loops, perform better Walls, Parachutes, or Waterfalls. Sometimes deployed only after 50% throw of the Elevator for 3D effect only.

ELEVONS - For an aircraft that is essentially a flying wing. The Elevators perform the function of ailerons as well.

CROW - Need separate servos for ailerons and flaps ...enables you to combine a spoileron/flaperon effect at the same time. Can virtually elevator straight down with this function.
