The Cassutt Special is a single-seat sport and racing aircraft designed in the United States in 1951 for Formula One air races. Plans are still available for homebuilding. Designed by ex-TWA captain Tom Cassutt, it is a mid-wing cantilever monoplane with fixed tailwheel undercarriage. The fuselage and tail are of fabric-covered steel tube construction, and the wings are built from plywood over wooden ribs. [1] An updated taper-wing design was first flown in 1971 on Jim Wilson's "Plum Crazy". [2]

Contents

Plans and parts are available from Creighton King of Salt Lake City, Utah, United States, for amateur construction. King also offers plans for the Stockbarger tapered wood wing. [3] [4]

Design and development

The aircraft is built with a 4130 tubular steel spaceframe fuselage and a plywood-skinned wing with solid spruce spar and built-up ribs. The design lends itself well to modification, there being several different wing options of wood or composite construction. [4] Several different tails have been built, including T-tails.

The standard engine used for competition is the 100 hp (75 kW) Continental O-200, while other, lower-powered engines can be used for recreational flying, including the other small Continental A65 and Continental C90. Cassutt Aircraft discourages the use of auto conversions or larger Lycoming engines. Lycoming’s have been successful in several builds but the increased weight rarely gives the desired performance boost.[ citation needed ]

The T-211 is a light aircraft designed in the US by John Thorp in 1945. It is a low-wing monoplane of conventional layout with fixed tricycle undercarriage and a sliding canopy. John Thorp developed the Sky Scooter with lessons learned from the developing the Lockheed Little Dipper project in 1944. It bears some family resemblance to the Piper Cherokee, a design that Thorp later contributed to significantly.

It is a low-wing cantilever monoplane of conventional design with an enclosed cockpit and tailwheel undercarriage. As originally designed, the main undercarriage units of the KR-1 and basic KR-2 were manually retractable, folding backwards into the wings, while the KR-2T tandem-seat version had fixed tricycle undercarriage. However, some builders choose fixed tailwheel or even fixed tricycle undercarriage for KR-1s and KR-2s.
