Jim, the first one I built wound up quite nose heavy, knowing then what I know now, I would have started pulling weight out of the nose. The plane needed massive amounts of up trim to fly level, but I was so afraid of it becoming tail heavy, I was reluctant to change the C.B.. As it worked out I tip stalled on take off and while the plane was repairable, I had given up, and gave the thing away.
When I get the one under construction finished, I do not thing I will have the same issues as before. Also, I have a weight range to shoot for, so if it looks like it is getting heavy, I can adjust.
