The Aircraft On Display

The display aircraft is a home-built Sindlinger HH-1, a 5/8-scale replica of a Hurricane Mark 1, construction number 26-10663. The description with the aircraft states "This aircraft was constructed by Arthur Winstanley in 7,500 hours over a 10 year period ... its first flight March 17th 1993 (piloted by Winstanley)."

Type History

Both the original design and the replica are significant in their own right:

Hawker Hurricane

The Hurricane had its origins in British Air Ministry specification F.36/34, but the Hawker response to this was rejected, leading its designer, Sydney Camm, to "go back to the drawing board" and generate a new design which used some of the components of the biplane Hawker Fury fighter.

While the Hurricane was in many ways obsolete at the start of World War II, its form of construction, based on the Fury's steel tubes with a fabric covering (the wings being metal-covered only after the war commenced) gave it good resistance to battle damage and "general wear and tear". This stood it in good stead during the Battle of Britain, when it formed the majority of the RAF's fighter squadrons. Afterwards, it also allowed it to be used for ground-attack roles, and in a range of theatres of war where strength and robustness were important - as in operations from aircraft carriers, and desert regions.

Sindlinger HH-1

The original HH-1 (a contraction of "Hawker Hurricane Mark 1") was designed and built by Fred Sindlinger, and first flew in January 1972. It was initially a "one-off" design, but interest at U.S. air shows led to the designer passing all his plans for the aircraft to professional designers (who reportedly made few changes), and then releasing it into the "home built" market.

It is not a true scale model, the cockpit and engine bays being slightly enlarged relative to the rest of the replica, due to the need to fit a standard pilot in the first, and a sufficient engine in the second. It is claimed that the designer chose the Hurricane for his replica because it was slightly larger than later designs, like the Spitfire and ME-109, so that these parts of the aircraft could be closer to their correctly scaled sizes.
