Design and development

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. This compact rotary motor allowed a sleek engine cowling, but the engine was rejected and production aircraft use 85 hp (63 kW) Jabiru 2200 or 95 hp (71 kW) ULPower UL260i engines. [2] [3] [4]

An electric aircraft version was under development in 2010. [3]

Propeller

The Twister prototype was fitted with Silence Aircraft's own automatic variable-pitch propeller called the "VProp". The LAA have yet to allow the VProp to be fitted on UK aircraft, so UK Twisters have fixed-blade propellers instead. [5]

Operational history

Twenty-one examples had been completed and flown by December 2011. [1]
