Thanks pd1....I really soked that info in...I remimbered some of that from ams school. But that was in 1984....LOL....It is funny how your mind can mix together info and get it wrong after 23 years. I appreciate all the troble you went too . So far I have moved the fuel tank to the CG ...Moved the nose wheel where the nose is 1/4 in taller than the main wheels Moved the radio and battery to get the CG right on the mark. I still have the big chunk of steel in the nose that came with the plane. I am thinking of shimming the engine to get 2 degree insidence up to help pick the nose up. What do Ya'll think? Also I was going to put 2 small micro servo's in the wing for rudders.
