[2] The Twister is a single-seat low-wing monoplane with elliptical wings and tailplane.

It has a retractable conventional landing gear with a fixed tailwheel.

[2] The design drew inspiration from the Supermarine Spitfire, and the shapes of the Twister's wings, fin and tailplane all recall the famous World War II fighter.

Designed to take engines up to 94 hp (70 kW), the prototype was fitted with a 53.6 hp (40 kW) single-rotor MidWest Wankel engine.

[3] The Twister prototype was fitted with Silence Aircraft's own automatic variable-pitch propeller called the "VProp".
