I posted this in the aero forum, but I though it might be more appropriate here.

A while back I asked for opinions why this Byron GeeBee was climbing (looping almost!) at full throttle and diving at low throttle settings. Well, I blocked it up and checked all the incidences and the engine thrust line. Now being a FG fuse with the horizontal stab and wing fairing molded right in, you'd think with a Byron kit there would be no problems.... Well I have -1 on the horizontal stab, +3 on the wings and 3 degrees of down thrust! The down thrust is fine but the others make for one crazy looping plane. It's possible I could have messed up the H stab maybe a degree but the wings are impossible to mess up the incidence. This is my first plane I've build that didn't fly perfectly strait on it's first flight. That's because I always check this kind of stuff. Thinking Byron had taken care of it for me was a mistake, but others that reviewed the kit said it had no bad habits (scared of losing a advertising account?). Any thoughts, maybe I should at least make the horizontal stab +1?

Thanks,
