I've been playing with the Black Magic 90 a bit on size. If I scale the fuse back to 80% of the 2M I get a 62 3/8" fuse tip of spinner to tip of tail. The wing at 82% gives me a 61 1/2 inch span and about 680 SQ. IN. if I include the fuse which I think is the correct way to do it. Otherwise each panel is 312 SQ. IN. The fuse is roughly 60 SQ. IN. The depth of the fuse is 10 3/4" at it's deepest. The YS 91 will fit within the cowl except for about 1/16 + or - a 1/32 or so of the valve cover.

This looks more workable to me and overall weight should not be as big an issue to hit on target. Or I could go as planned and put my YS 120 in the nose of my present version That is still a bit larger than I like though for transportation issues.
