This elegant V8 won ME Magazine's coveted Gold Medal at the 1995 Olympia Exhibition. A truly magnificent project yielding a 10.6cc 4 stoke glow plug engine that is guaranteed to turn heads wherever it is displayed or flown! Recreating an aero-engine layout that was popular in the 1920's, Eric Whittle's masterpiece closely resembles the Airdisco (Air Disposal Co.) 120 and 200 hp units used by Sir Geoffrey de Havilland in the DH51. The engine will swing a 12" x 6" propeller at 7,000 rpm yet idles smoothly at 2,500rpm. The engine is just 4" long with an overall weight of 15oz! With a 90o V8 layout using overhead valves actuated by push rods, the engine's bore x stroke = 0.460 x ". Mr. Whittle states that this is a straightforward engine to build, requiring no special skills or equipment. What is required however is patience! The award winning engine took 6 months to complete and contains a total of 550 components.

Through an introduction to Commander Wilfred Briggs, W O gained a commission in the Admiralty and was posted to the Rolls-Royce and Sunbeam factories where his aluminium alloy piston was adopted.The English concessionaires for the Clerget rotary aero-engine, which suffered from limited power and poor reliability, were next to receive a visit from W O. He proposed a number of modifications, including the use of an aluminium cylinder shrunk on to a cast-iron liner to improve cooling. These were taken up and resulted in a new engine, the BR1 (Bentley Rotary 1). This engine was so successful that ‘the Hun’ concentrated their attacks on zones in which they believed Camels fitted with the BR1 were based.
