The Wonderful Wizard of Auz

ZEPHYRUS

an elegant two seat 1960's glider from Australia

Designed by Douglas Lyon

Overview

The Zephyrus was born from the plans for a single seat glider in the 1940's, but due to the sudden requirement for a two seat trainer, the plans were to be modified to a two seater and this revision was started in in 1951. During the coming years, the build was to be significantly delayed due to a lesser need for the two seat glider and it was not until December of 1966 that the Zephyrus was finally given its' airworthyness certificate.

The fuselage is of welded steel tube construction with fabric covering whilst the wing is a design worthy of an artist and has proven to be effective in allowing 300+km distance flights to be recorded. An unusual feature is that the rear cockpit is accessed through a hinged door on the starboard side.

The glider is still airworthy today, based at the Beaufort Gliding Club at Melbourne and is shortly to be removed from service for a re-cover.
