The Pitts Special (company designations S1 and S2) is a series of light aerobatic biplane designed by Curtis Pitts.  It has accumulated many competition wins since its first flight in 1944. The Pitts biplanes dominated world aerobatic competition in the 1960s and 1970s and, even today, remains a potent competition aircraft in the lower categories

Curtis Pitts began the design of a single-seat aerobatic biplane in 1943 & 1944.  The design has been refined continuously since the prototype’s first flight in September 1944, however, the current Pitts S2 still remains quite close to the original in concept and in design.  Several of the aircraft that Curtis Pitts built had a picture of a skunk on them and were called “Stinkers”.  After she bought it, aerobatic performer Betty Skelton called the second aircraft that Curtis built, “Lil’ Stinker”. The prototype S-2, which was the first two-seat Pitts, was “Big Stinker”, the prototype Model 11 (later called S1-11B) was “Super Stinker”, and the prototype Model 12 was the “Macho Stinker”.  In 1962 Curtis Pitts set up Pitts Enterprises to sell plans of the S-1C to homebuilders.

Operational history

All single-seat (S-1) and two-seat (S-2) Pitts Specials are variations on the basic design from 1944.  The aircraft was popularized by Betty Skelton, Caro Bayley and other air show performers, which led to the offering of plans in 1962.  Pitts produced limited numbers of aircraft during the 1940s and 1950s. It is widely accepted that the Pitts Special is the standard by which all other aerobatic aircraft are judged. After a number of home-built aircraft were produced from rough hand-drawn plans produced by Pitts, more professionally drawn plans went on sale in 1962. While many home-built aircraft were built in the 1960s, earning the S1 a reputation as an excellent aerobatic aircraft, Pitts worked on the design of a two-seat aerobatic trainer version, the S-2, which first flew in 1967 and gained its type certificate in 1971. Factory-built aircraft produced by the Aerotek company at Afton, Wyoming were joined in production by the single-seat S-1S in 1973.  The design’s popularity grew significantly following Bob Herendeen’s participation on the USA Aerobatic Team in a Pitts Special in the World Aerobatic Competition in Moscow, Russia in 1966.  In 1972, the US National Aerobatic Team won the World Championships flying only Pitts biplanes. In 1977 Curtis Pitts sold his interests in the Pitts S1 & S2 to Doyle Child. Child later sold the rights in 1981 to Frank Christenson, who continued production at the Afton plant under the guise of Christen Industries.[8] The rights for home-built versions of the Pitts were sold in 1994 to Steen Aero Lab, with the Afton factory and production rights being transferred to Aviat.  Curtis Pitts died in 2005 at age 89. At the time of his death, he was working with Steen on the prototype of the new Pitts Model 14, a brand-new, two-seat biplane designed for unlimited aerobatics powered by the 400 horsepower Vedeneyev M14P radial engine. The rights to the Pitts name is currently owned by Aviat which also owns the similar model to the Pitts in the Christen Eagle.[10]
