Design and development

The aircraft has a classic structure consisting of a welded tube fuselage and wooden wings, all fabric covered. It is a tandem open-cockpit two-seat biplane and is stressed for normal aerobatics. The cockpits are frequently constructed as a single tandem cabin with an enclosing bubble canopy. Some aerobatic competition aircraft are built as single seaters with the front cockpit closed off.

The original Skybolt had a 180 hp (134 kW) Lycoming HO-360-B1B engine, but powerplants of 150 to 260 hp (112 to 194 kW) can be installed.
