RE: Wave King CG?
I have a Wave King (60 sized) partially built in my collection of aircraft. Construction came to a grinding halt when the fuselage fell over in the shop and the plastic bottom split open about 3" long just behind the step.
Does yours still have the plastic fuselage or did you find a fiberglass one somewhere? C/G is about 3"- 3-1/2" rear of the leading edge. It's not too critical with such a long fuselage. I was thinking of scratch building a new fuselage along the lines of the Drake.
