Ollie,

Thanks for your comments. Now I realize there is some more details that I left out of my original post.

I've been building my racers with everything set to 0-0. Engine, wing and tail. These airplanes turn great! On the upwind you bank to near verticle and yank the elevator and hold until you're looking almost straight at the airplane, let off the elevator and roll slightly right and the airplane will do the entire downwind at near knife edge. Then bring the airplane around two and three. It seems that very little speed is lost in the turn. There is no tendency for the airplane to drop the nose in the turn or snap. In fact these turns are really fun! Especially if your passing someone at the same time! I was really wondering if setting the airplane at zero zero was the best thing to do from a drag perspective. As you may have guessed I could use some more speed. The mh33 foil is a 6.28% thickness. Maybe I could go a little thinner? Rgds,...... Jeff.....
