RE: GP Illusion info needed
Arturo,
hope this might help. The picture is the best I can do as I don't have the plan of sorts. What's interesting is that the wing and stab relationship is such that the wing top and stab bottom touch the fuse thrust line. This was one of the the main differences between the Tiporare and the Illusion. Another was the reduced dihedral on the stab and the increased wing area from 720 to 750 squares.
You could probably scale this photo to obtain the planforms and airfoils with the understanding that accuracy would be questionable.
David.
