RE: Mach 1
I agree, not a Mach 1. I built 4 of the over several years. I sold a fixed gear version and a retract gear (Goldberg) version a couple of years ago at a swap meet. Mine were always toooo heavy but I loved the way they looked in the air. Nice lines. Hated the thin fuel tank setup.
I would love to have one about 2 pounds lighter than my usual model turned out.
