RE: Pica 1/5 P-51 Mustang. How scale is it?
IMHO, the Pica P-51 definitely has a better outline than either the Byron/Iron Bay or the Top Flite kits. Also, at 89 inches, it is the closest to being exact 1/5 scale. The biggest deviation from scale is probably the airfoil which is quite distinctive on the full size airplane (laminar flow section). However, for a giant sport scale bird the Pica Mustang is better than most in the outline department. (which cannot be said for their Spitfire or P-40!)
