History of the Pitts Special

It is hard to believe that it was as long ago as 1943 when Curtis Pitts built the first of a series of aircraft
that would dominate competition aerobatics throughout the 70s and 80s. Christened the ‘Pitts Special’,
it went on to be the most successful and easily recognised American-built aerobatic design. It was
certainly evolutionary and because of its small size, light weight, short wingspan and extreme agility, it
remained unbeaten until it was finally toppled by the Russian Yak-50.

While there have been many versions of the Pitts Special - in both single and two seat versions - it is
widely accepted in the aviation community that the Pitts Special is THE standard by which all other
aerobatic planes are judged - and few have ever matched. The design has been continuously refined,
however, the current Pitts Specials still remain close to the original in concept and in actual design... a
testament to the genius of Pitts’ original concept.

Wingspan: 5.28 m (17 ft 4 in) • Length: 4.72 m (15 ft 6 in) • Weight: 290 kg (640 lb)
