RE: WHAT ARE THE CG'S
there is a rule of thumb....from the leading edge of both wings but a mark 1/3 the width of the wings from the leading edge..ie if the wing cord is 30 inches...from the leading edge make a mark at 10 inches....now connect the 2 marks on both wings with an imaginary line...CG will be half way between the wings..This is not gospel but a ball park figure that will be real close....you may need to adjust after the maiden flight
