Default Calculate CG on odd wing??
Ok, Guru's

a friend is on a SPAD building terror!

He is going to build a Draco based spad, but he wants to sweep the wings back..... but not all the way from the fuse....

With a wing of the shape shown in the picture... how would we calculate CG???

Any help or insight would be great!!!



The leading edge at the Fuse is straight (90 degree from the fuse) then at the sweep (15" from centerline of fuse) he wants to sweep back approx 20 degrees......
the chord should be a 15" constant from fuse to wingtip.....
