The Sequio 300 Sequoia is an American two-seat utility or aerobatic aircraft, designed by David Thurston for Sequoia Aircraft Corporation for sale as a kit or set of plans for homebuilding.
The Sequioa, derived from the smaller Frati designed F.8 Falco, is a low-wing cantilever monoplane with a retractable tricycle landing gear andpowered by a 3000NaN0 Textron Lycoming TIO-540-S1AD turbocharged piston engine, although it was designed to take any Lycoming engine between 235-300 hp (175-224 kW). It has an enclosed cockpit for two with side-by-side seating.
The design was originally proposed in the 1970s but the first prototype did not fly until 26 April 1992 and by 1993 the program was being offered for sale.
