In the car it would take a long time to reach cruising speed, in the Spitfire you would run out of runway. In the aircraft this allows a shorter take-off run, and protects the engine from detonation вЂ“ which you would experience in a car if you drove off in too high a gear. Having a variable pitch (or extra gear) means that for a given RPM, you can increase the thrust in the same way that changing up a gear drives the bicycle forward with greater force. The gearing you have with this is a вЂone size fits allвЂ™ compromise, allowing you to move off from standstill, and still reach a reasonable top speed. Having a fixed-pitch rather limits the performance of the aircraft, similar to riding a bicycle with only one gear. By the end of the war, the Spitfire had been through 13 different designs.ДЄt the very beginning, the prototype and the initial Mk1s that followed it had a wooden two-bladed, fixed-pitch prop, which was the standard of the time. Supermarine Spitfire Mk. Thanks to Philip Simmes you can print it the same way as the rest of the plane. Getting a working three or four-blade propeller for one of our most successful warbirds, the 1.6 m Spitfire Mk.

Spitfires used a variety of propellers during their time in service. A nice, scale looking propeller is a great final touch for every plane.
