Fastest propeller-driven aircraft
The more "traditional" class of propeller-driven aircraft are those powered by piston engines, which include nearly all aircraft from the Wright brothers up through World War II. Today piston engines are used almost exclusively on light, general aviation aircraft. The official speed record for a piston plane wass held by a modified Grumman F8F Bearcat, the "Rare Bear", with a speed of on 21 August 1989 at Las Vegas, New Mexico, United States of America. This record was retired as a new weight class based system was introduced to allow more pilots to set new records across a wider range of aircraft. On september 2, 2017, Steve Hinton Jr, in the modified P-51 Mustang "Voodoo" set the new record of in the C-1e class (the same weight class Rare Bear would fall into). This record is also the fastest for any propeller driven piston aircraft.
