steve04,
It's my belief that the wings on the UCD are fully semetrical. I think the ailerons should follow the middle of the wing. I think this plane lands a little better with a small amount of spoileron, especially when it's a bit windy.
I don't think the UCD is prone to flutter if you fly it slooooooow. Made for pure 3D thrills, not a speed demon. It will land easier than any plane you've flown if you bring it in slow and straight.
Great fun plane. If you fly on low rates, super easy to fly and land, if you fly on high rates, WOW!
Thanks
Bud
