I believe its about 93" ws. I've done some calculating and what I come up with is around 37% to 40% at the wing root. This is also confermed on a 56" ws set of Cleavland plans I inherited. But it just does'nt look right that far back. Jaka, where did your cg end up percentage wise! If this conversion program worked right I believe it says yours has about an 83" ws, correct? Its been awhile since I looked at the plans but I think it stated .40 2-stroke engines. Its a pretty old design. I'm planning on dropping about 10 fire jumpers from mine. I have an idea to use a rotating spring that should pop them out one at a time. Easier to picture than to explain, just dont have a picture.
