The Sunbird is a single-seater homebuilt motor glider, designed and built in New Zealand by Charles Stanton. It first flew in 1995, and was retired in 2005.[1]

Design and development[edit]

Charles Stanton of Nelson, New Zealand had previously built and flown an AmEagle American Eaglet motor glider, registration ZK-GOE (c/n AACA/641).[2] That craft's registration was cancelled in 1992. Stanton then went on to design and build a motor glider, and utilised components from the American Eaglet. Construction took over three years, and was completed by early 1995.

The Sunbird was a self-launching motor glider.[3] It was a high-wing monoplane of conventional configuration, with a pod-and-boom style of fuselage. The cantilevered wing had no dihedral and its planform was of constant chord with a tapered outer section. The pilot was housed in a small faired nacelle. The engine was located at the rear of the nacelle, and powered a two-bladed folding propeller.[1] The engine was a 21 kW (28 hp) Rotax 277, which could be re-started in flight.[4] The empennage was of the standard type arranged in a cruciform configuration. The undercarriage was a fixed monowheel fitted with a wheel spat. The Sunbird met the New Zealand specifications for Class 1 Microlights, and was issued with the registration ZK-JEA.[3]

Operational history[edit]

It first flew on 26 February 1995, with Stanton reportedly making numerous flights in it over the next ten years. On one flight, it reached an altitude of 4,000 m (13,000 ft). Another flight lasted for 3+12 hours. The craft's final flight took place on 16 April 2005. It was donated to the Ashburton Aviation Museum on 4 December 2005, during the Museum's Christmas Party.[3]
