Pitts S-2
Pitts S-2B
It was not until 1967 that Pitts introduced the two-seat S-2A. Although similar to the S-1 in configuration and construction, the S-2A is slightly larger in overall dimensions and shares little commonality in components. In 1973, five 200-hp S-2As were supplied to a British aerobatic team sponsored by Rothmans Tobacco. Five more S-2As were later supplied to the Carling Black Label team in Toronto, Canada. And in mid 1976, the Peruvian Air Force announced an order for six S-2As, for "an unspecified training role." The single-seater's popularity has been partially eclipsed by that of the two-seat version, the S-2A, which went into production early in 1971, and of which nearly 140 have been sold by 1977.

The S-2A is slightly larger in all dimensions than the S-1; no attempt was made at commonality of structure. A tandem two-holer with a 200-hp Lycoming engine and a constant-speed prop, it is not a tiny airplane. Both wings use symmetrical airfoil sections, the upper considerably thicker than the lower; they are set at an incidence that compromises between the requirements of upright and inverted flight, so that the airplane feels slightly nose-high in cruise but comfortably level when inverted. The cockpits are fairly roomy, but the instrument panel is inches from your face, and the optical distortions caused by the edges of the corn-pound-curved windshields add to an already (and inevitably) cluttered view. Canopy hoods of plexiglass may be fitted, at the expense of intimacy with the air. The hoods reduce the unpleasant forward pressure of the wind on the rear-seat pilot. The cockpit sides are high, blocking visibility, which in the landing disappears altogether. Any object carelessly dropped finds its way into the far end of the tail cone, there to interfere with the elevator controls.

Besides its legendary ability to snap roll several times in succession with little loss of rate, the Pitts is notable for its willingness to be held in any attitude and yet to recover on command. As well as being a highly qualified aerobatic competitor, the S-2A is also ideally suited for advanced aerobatic instruction. It is a two-place aerobatic biplane that offers the student the opportunity to learn aerobatics under the supervision of an instructor.
The S-2B is a two-place 260hp aircraft. Wings and landing gear moved forward 6 in to balance the larger engine.

The S-2E price in 1982 was $50,800 as a complete kit. Units delivered to June 1982: 75.
The S-2S is identical to the S-2A except for the forward fuselage which has been shortened 14 inches to accommodate the larger 285hp Lycoming IO-540 engine, with the wings nine inches further forward and a number of other differences such as symmetrical ailerons which increase roll rate over other Pitts by 60"/sec (Up to 240"/sec). In addition, the front cockpit has been eliminated, making it a single-place plane. The S-2S’s larger size makes it ideal for air show flying as well as aerobatic competition. Its cruising speed of 175 mph combined with its fuel capacity of 35 gallons also gives it excellent cross country capability. With a 5 lb/hp and thrust/weight ratio of almost 1:1, it can, for example, do three vertical rolls in full competition, climb 300ft/min in knifedge and hover for "three or four seconds" at the end of a vertical climb. Climb rate is around 3,000ft/min and its snap roll rate is something like 480o/sec, and other party tricks include the ability to pinwheel, which is a stall turn through 540 degrees.
The first S-2S received its certification in mid-1981. The S-2S price in 1982 was $56,550 as a complete kit. Units delivered to June 1982: 10.
1972 Pitts Special S2A
The S-2, S-2A, S-2B, and S-2S are certified under FAA A8SO.
The S2-S was not a Pitts product, but a single place experimental home-built.
