RE: question about c.g.
What are you using as the balance point for this plane??
According to the manual the plane should be balanced at a point 3" back from the leading edge of the wing. Turn the plane over, measure back three inches from the leading edge from the wing, place a mark there, turn the plane back over, and place it on the CG machine on the marks you made on the wing. Then balance accordingly.
