I think gliders have spoilers on top of the wing (near the center of lift) where they cause airflow seperation from the wing. This would be in addition to ailerons. Has any one tried to use "crow"? I think this is where spoilerons or flaperons are mixed with elevator to act as a speed brake.

opjose. Do the spoilerons really work for you? I plan on playing with these functions on a Shrike 40 I'm building.
