You may want to also check your engine thrust. If the engine is pointing up it needs to be shimmed down to even and maybe a little down thrust. Any of these item will make it fly like you say. If it is tail heavy just a a couple of ounces of lead to the nose and check it again. The wing incidence issue, as mentioned can be fixed with shims. The instruction manual should tell you want the correct incidences are and you do need a meter to check them. Good Luck, Dave
