The names used by Chris Butler for his products are all evocative! The historians of British fighter aircraft from WWII among you will certainly recognise the names of: Tempest, Fury (used by the Hawker Company) and, of course, the most famous of all Spitfire! The models called Tempest and Fury were fitted with a Villiers 32A engine with a cast iron barrel on the early models which was replaced by an aluminium type (Parkinson) on the later versions. The Spitfires were equipped with th ‘Starmaker’ engine from Villiers. All engine capacities were 246cc (66x72mm) and gave around 12bhp with a four-speed gearbox with the following ratios: 8.1 / 10.7 / 19.2 / 28.8. Suspension was provided by Girling.
