The Ultimate Aircraft 10 Dash is a Canadian single-seat sport and aerobatic biplane designed and built by Ultimate Aircraft Corporation of Guelph, Ontario.[1]
The 10 Dash Model 100 was designed as sport biplane that could be either bought assembled or for amateur construction from either plans or a kit. The first prototype 10 Dash 100 first flew on 6 October 1985. It is designed to have either a 1000NaN0 or 1800NaN0 engine fitted for example a 1000NaN0 Continental O-200 engine. It is a braced biplane with wooden wings, a welded steel tube fuselage, fixed conventional landing gear with a tailwheel and a single open cockpit. An aerobatic variant, the 10 Dash 200, is powered by a 180-200 hp engine. A competition aerobatic variant, the 10 Dash 300 can be fitted with either a 3000NaN0 or 3500NaN0 Lycoming engine with a three-bladed propeller. The 10 Dash 300 has a longer fuselage and longer-span wings with full-span symmetrical ailerons. A tandem two-seat variant, the 20 Dash 300, also joined the family.
