World Models Code A173S1 33% Yellow/White Ultimate
The now famous Ultimate 10-300 originated as Full-Scale Pilot/Designer Gordon Price's desire to improve the looks and performance of his Pitt's Special. After he had produced new wings, canopy, fuselages, and wheel pants for the Pitts, it was a natural step to produce his own airplane.
The original 10-100 flew with a 100 HP engine, and while the plane flew well, vertical performance was limited. The next version (10-200) was 6" longer, and could accommodate a larger power plant, but eventually, Gordon updated the design to the 10-300, which was 3 feet longer than the 200, and could handle a 300 HP engine.
The rest, as they say, is history.
