Flaperons, Spoilerons typically in RC aerobatics planes is talking about ailerons that react via a mix to what the elevator is doing.

With Flaperons (Elevator/Flaps moving opposite one another) if the elevator goes up, the ailerons move downward together and vice versa according to the proportion set in the mix. But they STILL work together as ailerons at the same time to maintain roll control. This provides more lift at lower speeds.. But what its normally being used for is to tighten up looping maneuvers like waterfalls and knife edge spins.

With spoilerons (Elevator/Flaps moving the same direction) if the elevator goes up, the ailerons go up and vice versa proprtionally to the mix. This is a DANGEROUS mix because it severly magnifies the wings stall tendencies as up elevator is applied. It can be used to slow a fast plane down for a landing approach or for aerobatic purposes. If you use spoilerons you better know EXACTLY what you are doing because they will crash you and there wont be anything you can do to stop it if you dont know what you are doing.

Really spoilerons defy logic for anything considered normal flight. Using the ailerons for spoilers is fine but not really on a mix with elevator. Having a switch that will put a small amount of up ailerons(reflex) for landing is fine but you need to understand what it does to lift because the plane is going to sink faster and stall at a higher speed. Most guys I have seen use spoilers flip the switch just as they flare to slow the plane as it touches down and slows to a stop.




NOW, Spoilerons from a 3D standpoint can be a BLAST! Typically the proportion is very high so that the mix raises/lowers the ailerons a lot *****g out the reflex at 20-60 degrees as you move the elevator to full high rate 3D deflection![8D] But you better know how to use them and whats happening.


For an "elevator" maneuver (3D manuever) they will increase the descent rate and slow or stop wingrock BUT at the bottom of the maneuver, if you leave them in and pull up elevator to fly out, you will probably crash. Spoilerons are NOT conducive to flight and the plane will not fly with spoilerons worth a ,,,, well,,,, it just wont fly. I have mine on the spring loaded trainer switch so that I pull the switch, do the maneuver and then let the switch go(kills the spoileron mix) and fly out with normal flight control.
