Hey thanks for the pics, have not cut any on windshield, those will help. Have you tried larger diameter prop? Have been reading some guys use up to 18/6 prop with Saito 180. Yes mine is inverted, I have an old on board glow but have not fired up engine yet. You did not like it inverted?

I see you want to add dihedral to the wing. Have to go back & check but the wing is 0 degrees at root & 2 degrees positive at tip (something like that, I have to check manual) and stab is negative 2 degrees. I don't have incidence meter, but am going to find someone who does. Will take it to them & have it checked before I go much further on build. The stab is not yet glued on (just held with some very small screws) for that reason. Did you check incidences on wing & stab ?

What is it you don't like about the handling of the plane?
