The Parnall Pixie was a low powered British single-seat monoplane light aircraft originally designed to compete in the Lympne UK trials for motor-gliders in 1923 where it was flown successfully by Norman Macmillan. It had two sets of wings one for cross-country flights and the other for speed; it later appeared as a biplane which could be converted into a monoplane.
