Thanks guys; I am really amazed at how well this thing fly's. After I put heavier wheels on it, and tweeked the outboard flap a little, it fly's better than my 28 ounce Ringmaster. At about 30 ounces with only 338 square", I was doing triangles and hitting that bottom corner as hard as I could without a stall. Flaps a big deal on this plane. With the heavier wheels and warped flap it now fly's flat upright and inverted.
