I think I'm good! My CG is right on the main spar with tank empty, my CG (or finger balance point) is within the limits according to the calculator with or without the ailerons included in the wing chord. I will have an instructor take it up and trim it for me just to make sure because I am a newbie. The throws are toward the low end.

Aerowoof, one more question: Wing loading w/empty tank is about 18. With my wing area at 780 sq. in. are you telling me by your rule of thumb this plane could handle 7.8 lbs. without being a tank? Right now it wieghs in at abt. 6 lb. Doesn't engine size also factor in?

And what about prop size and pitch? I'm wanting it to be a "gentle" trainer at this point. (Maybe this should be in the aerodynamics forum). It has a 10 X 6 prop now. Help a newbie get his head around thrust etc. Thanks.
