FSX/P3Dv3,v4 Pitts S2A
Curtis Pitts began the design of a single-seat aerobatic biplane in 19431944.The design has been refined continuously since the prototype first flew 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, "Little 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.
Aerotek-built S-2A with a 200 hp (149 kW) Lycoming AEIO-360-A1A or -A1E piston engine, constant speed propeller, later builds have a longer landing gear and a 2-inch-wider (51 mm) front cockpit; 259 built
Operational history
Pitts produced limited numbers of aircraft during the 1940s and 1950s. The Pitts Special became the standard by which all other aerobatic aircraft were judged. After a number of homebuilt aircraft were produced from rough hand-drawn plans produced by Pitts, more professionally drawn plans went on sale in 1962. While many homebuilt 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 In 1972, the US 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 Christensen, who continued production at the Afton plant under the guise of Christen Industries. The rights for homebuilt 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. 
The current inverted flat spin world record is 98 set on March 20, 2016 by air show performer Spencer Suderman over Yuma, Arizona. Suderman flew the Sunbird S-1x, a Lycoming IO-540-powered experimental variant of the Pitts S1. The maneuver began from 24,500' over the Yuma Proving Grounds and was recovered at 2,000' AGL. The previous world record for the number of consecutive turns in a flat spin was 81 also set by Spencer Suderman on March 13, 2014 in a Pitts S2-B from 23,000 ft altitude over the Naval Air Facility El Centro.

-Read instructions carefully when installing the gauges ,  say YES...when asked if the gauges sources should be trusted. If you say no....most of the gauges are not going to work !
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-Leave the gauges cab in your panel folder.
IMPORTANT : 
-This model is native FSX and P3D4 and doesn't work in FS2004.
