No that's not a Mach 1. Not even close. I have one in a box my wife gave me in the early 70s. May finally build it this year. Retirement helps. Yup the Mach one has a straight leading edge and tapered trailing edge. Canopy is a smallish thing that runs to the tail. This thing was designed when heavy was the norm (penetration). I think I can fix that with a hole saw and some circle blades.
