The Pitts Special, Curtis Pitts, and the Little Biplane That Built American Aerobatics

AVweb’s Picture of the Day on September 18, 2026 featured a formation of Pitts Specials in flight. The image is striking not because it is unusual, but because of what it represents. The Pitts Special is one of the most consequential aircraft ever built in the United States - not because it carried passengers or broke distance records, but because it taught America how to fly aerobatics at a world-class level, and it has never stopped.

How Curtis Pitts Designed an Aircraft That Outlasted Its Era

Curtis Pitts was a self-taught designer and mechanic from the American South who began developing the Pitts Special in the 1940s with limited resources and a deep intuition for how airplanes move. In 1944, he drew up the core concept: build the smallest, lightest, most agile biplane that could safely carry a human being, then make it strong enough to do whatever that human being demanded.

The first prototype flew in 1945 - single-seat, fabric-covered, and modest in horsepower, but right in its fundamentals. The short wingspan, the staggered biplane configuration, the tight fuselage. Pitts understood that aerobatic performance comes from eliminating everything that does not contribute to maneuverability. Every added pound, every extended inch of wingspan, every increase in moment arm is paid for in every snap roll, every hammerhead, every outside loop.

For years, the aircraft spread through the homebuilt community as a plans-built design. There was no factory, no dealership - just blueprints, guidance from Pitts himself, and a community of pilots willing to put in the shop time.

The Roll Rate That Changed American Aerobatics

Through the 1950s and 1960s, American pilots competed at the world aerobatic level without a dedicated competition aircraft. Eastern European designs - particularly the Zlin from Czechoslovakia and Soviet Yak-18-derived aircraft - were well-funded and purpose-built for the discipline. American pilots were improvising.

The Pitts Special ended that. The aircraft’s defining characteristic is its roll rate. In fully developed form, the S-1 series can exceed 360 degrees per second - some configurations go beyond that. The aircraft does not transition through a roll; it snaps from one bank angle to another. You input, and it happens.

In aerobatic competition, judges score how cleanly and symmetrically each figure is executed. A slow roll rate means the aircraft is in transition longer than it should be, and that shows in the scores. The Pitts Special’s snap response gave American pilots a crispness that was simply not achievable in heavier, longer-winged aircraft.

The 1972 World Aerobatic Championships and the American Breakthrough

By the early 1970s, the United States Aerobatic Team was flying Pitts Specials and competing seriously for world titles. The pilots who defined that era - Gene Soucy, Charlie Hillard, and Tom Poberezny - remain central figures in the aerobatics community. Between them, they accumulated world championship titles and established the United States as a power in international competition.

The 1972 World Aerobatic Championships marked the turning point. American pilots finished at the top in ways that simply had not happened before. Pilot training, coaching, and organizational effort all contributed - but the aircraft made it possible. You cannot win at the world level in a machine not designed for it.

The S-2 Series and the Engine That Made Aerobatics Teachable

Curtis Pitts continued refining the design as competition results came in. The S-2, the two-seat variant, gave pilots and instructors a shared training platform in the same aircraft type. Engine options expanded as Lycoming developed powerplants specifically suited to aerobatic demands: the AEIO series - fuel-injected, with oil systems designed to operate inverted - became standard in serious Pitts variants.

The S-2B, the most widely used two-seat version and the backbone of aerobatic training programs across the country, carries a 260-horsepower Lycoming AEIO-540. That is a substantial engine in a very small airframe. The power-to-weight ratio is serious, and combined with the aircraft’s roll response, the S-2B does not forgive inattention.

What Pilots Need to Know Before Flying a Pitts Special

The Pitts Special is not a Cessna 172 with extra performance. It is a different category of flying experience, and it demands preparation.

Forward visibility over the nose during the landing flare is essentially zero. The approach is flown by looking out the side of the cockpit, and the transition to a three-point attitude is judged by feel and sight picture - not by looking straight ahead. On short final, the aircraft’s nose-high ground attitude means a pilot is looking at more sky than runway. Pilots who skip proper transition training get into trouble quickly.

This is not a reason to avoid the Pitts. It is a reason to find a qualified instructor and complete a proper aerobatic course before flying one. The International Aerobatic Club (IAC), which operates as a division of the Experimental Aircraft Association (EAA), maintains a nationwide database of aerobatic instructors. The IAC also runs chapter competitions at every skill level - from Sportsman through Unlimited - and those local events are accessible to any pilot willing to commit the time. Aerobatic training sharpens coordination, deepens aircraft awareness, and improves recovery instincts across every category of flying.

Aviat Aircraft: The Pitts Special Still in Production

Aviat Aircraft in Afton, Wyoming - a small town in the Star Valley - has manufactured the Pitts Special since taking over production from Christen Industries in the 1990s. Today, a customer can order a factory-built S-2C, the current production model, with a 260-horsepower engine, modern avionics options, and the same basic airframe geometry Curtis Pitts drew up in 1944.

Most aircraft designs from that era exist only in museums or as homebuilts maintained by dedicated enthusiasts. The Pitts Special is still in production. New examples are still being delivered. It did not survive as a relic - it survived as a working aircraft that pilots are still choosing to buy and fly.

Curtis Pitts lived to see his design become a legend. He passed away in 2005, by which point the aircraft had won world championships, trained thousands of aerobatic pilots, and become as closely associated with American aviation identity as the Stearman or the Waco. He started without a factory, without investor backing, without a formal engineering degree - only an idea about how a biplane should move. Aviation history is full of well-funded programs that produced mediocre aircraft and under-resourced efforts that produced machines that changed the sport. The Pitts Special belongs definitively to the second category.

What Formation Flying in a Pitts Special Actually Requires

Formation flying in a conventional trainer already demands precision, communication, and situational awareness. Formation flying in a Pitts Special multiplies every one of those demands.

The roll rate that makes the Pitts exceptional in solo aerobatics becomes a liability in formation if precision slips even slightly. The gap between correct throttle, correct spacing, and one small over-correction closes very quickly. Formation aerobatic teams flying Pitts Specials train constantly - this is not a discipline entered after a few hours of flight review. The aircraft will impose consequences before the first turn is complete.

What the AVweb formation image shows is the product of sustained, deliberate practice. That is what the Pitts culture has always represented: pilots who want to know exactly what they and their aircraft can do, passing that standard from generation to generation. The biplane era in commercial aviation ended decades ago. The Pitts Special never got the memo.

Key Takeaways

• The Pitts Special was conceived by Curtis Pitts in 1944 and first flew in 1945, starting as a grassroots homebuilt and becoming the foundation of American aerobatic competition.
• The S-1 series roll rate - capable of exceeding 360 degrees per second - was the technical edge that made U.S. pilots competitive at the world level.
• The 1972 World Aerobatic Championships marked a breakthrough for American aerobatics, with Pitts-flying pilots Gene Soucy, Charlie Hillard, and Tom Poberezny leading results that had not been achieved before.
• Aviat Aircraft in Afton, Wyoming still manufactures the Pitts Special; the S-2C is the current production model with a 260-horsepower engine.
• Pilots interested in aerobatics should start with the IAC instructor database; local chapter competitions run from Sportsman through Unlimited and are open to pilots at all experience levels.
