Try it, it works!

I crashed mine and wrecked the wing. When I built a new one I enlarged the hole where the servo goes and put 2 in. Flaperons let it fly really slow, spoilerons make it drop like a stone. Spoilerons also help with inverted flight.

I'm running out of things to change on this plane - it's a taildragger, the tail is bigger, and the ailerons are a little bigger -(instead of sanding the LE, I just glued some triangle stock to the front). It's actually pretty aerobatic now.
