GG~~Another thanks. I may well try this.... in time. Right now, I'd prefer the lift and drag to perfect the launch mechanism. I had already noted the major amount of lift as it gains speed and had had to trim it way down as a result. That trim down, motor alignment pushing the nose down, and the lack of airspeed off my launcher resulted in a lot of belly-out COT's and bloody nosecones. Maybe when I get her launching, I'll become more concerned about speed. They certainly do glide nicely. Piece of cake to land. How did you make the wing symmetrical? And what, exactly, is the "proper" CG? WC[sm=bananahead.gif]
