Stef, You and your dad have done some fine work on your KR. Use the CG location established in the plans but don't use the rear two inches of the CG. The CG is based on the wing plan form, not what is attached to the wing. It is based on the center of lift for that wing shape. Place your engine to keep you in the CG range with different loading configurations. More forward is best. Larry Flesner
