Definitely a plane I enjoy when I get it out.
I think I need to clarify a couple of things. I am a great admirer of Andrew Jesky and was looking forward to purchasing a plane developed by him. The plane did not come from the factory with his design specs. I am not trying to fine tune the plane to pattern specifications. I only wanted a flyable plane to practice pattern maneuvers and out of the box this model was not.
In spite of the cg set to 7 inches recommended by AJ, the plane dove during normal flight. When I flew it inverted it climbed. During a vertical down line it tucked to the wheels. Something happened during manufacturing. If the plane would have flown neutrally I would have had no issues at all.
A robart incidence meter is a $40 tool and is easy to use.
The rest of the fix has been covered in earlier posts.
