Thanks for pointing out that trimming is time well spent! Look how crude it is but it still flys, what up with that! Honestly I can't bear to think of taking it apart right now so I'm thinking I'll pull apart another bipe and *very* carefully make another one, record dimensions and use a CF rod & the smallest stab possible, after trying to move the lipo etc on the prototype. I got no software to make drawings like you guys. Coolest would be to eliminate the stab, rod & rudder altogether. Mind is reeling now, thinking NC-1701, childhood dream of flying the starship enterprise!!! Imagine that, props on the engine nacelles, WHOOH! WHOOH! More of a challenge than I'm ready for now but maybe someday... I think now I need to sort of reverse-engineer where I'm at with this model, I will spend a couple of days doing the math to prove it out. I'm really encouraged though, I was thinking that a round wing might not be so succeptable to changing wind in turns etc., and this tends to suggest that. I did some research and I found no successful full size aircraft that have round wings, the Sack AS-6 was a failure and the only others I found were like flying saucers or some such and that's rather loopy.
