I am currently working on a delta winged plane similar to Valkyrie XB 70. I am not a scale master but I already built the plane which looks alike, but nobody knows where is CG and aerodynamic center. I planned to put cg 13 inches back from the leading edge of root chord. But now I am not sure, whether it is the correct number.
Sorry about my questions but my club members do not know delta wing and rear engines with pusher props. So I want to learn not to meet a surprise at flight area and meet a person saying 'you had to have two degrees of thrust angle or something else'.
Again thank you very much.
