Design and development[edit]

The Dart Kitten was designed by A.R. Weyl in 1936 and built by Dart Aircraft Ltd at Dunstable, Bedfordshire. It is an ultra-light single-seat low-wing aircraft with a fixed tailskid undercarriage. The four examples built were powered by a variety of engines of between 27 h.p. and 40 h.p.[1]

Operational history[edit]

The Dart Kitten I G-AERP first flew in January 1937 and was sold to a private owner at Tollerton airport near Nottingham. It was stored during the Second World War. It was re-engined with a 40 h.p. J.A.P. J-99 postwar and flew with a private owner at Broxbourne airfield Hertfordshire before crashing there in November 1952.

The Dart Kitten II G-AEXT received its authorisation to fly on 30 April 1937 and had a series of owners before being badly damaged in a crash at Willingale, Essex in November 1964. It was subsequently rebuilt and in 2009 was airworthy with a private owner near Aylesbury Buckinghamshire. As of 2012 it is based with the Real Aeroplane Company at Breighton near Selby in North Yorkshire.

The Dart Kitten III G-AMJP was built by Dart Aircraft in January 1952 and was flown by owners in Buckinghamshire, Wiltshire and Lincolnshire before being lost in a crash near Kings Lynn in June 1966.[2]

A fourth Kitten was home-built at Port Moresby New Guinea in 1960 and registered in Australia as VH-WGL.[3]
