Peanut Scale

Wingspan 13”

Power Rubber

By WALT MOONEY

 Perhaps one of the prettiest fighters ever built, the Spitfire was even nicer, in my viewpoint, as converted from the Spitfire I to a special standard (Type 323) for an attempt at the World's speed record. This airplane ... there was only one Spitfire so converted ... was specially cleaned up aerodynamically, with a shortened wing, flush riveting, a cleaner canopy and a smooth glossy paint job. It was equipped with a more powerful engine that required the installation of a larger radiator and oil cooler. A special fixed-pitch four bladed propeller was used. Both Heinkel and Messerschmitt produced airplanes that outstripped the Spitfire's speed capabilities before it had a chance at the record, so no record attempt was made with it. But from my point of view it sure looks nicer than either of the aforementioned aircraft.

This Peanut version was built for the Flight masters Speed contest and is quite rugged. It was flown with two loops of
quarter flat rubber and enough balancing clay on the nose to put the CG directly above the wheels, in an attempt to hold down the climb. It achieved almost 30· mph, which is almost twice what you can expect
