CIRCLE CW AIRCRAFT

This aircraft is the second version of an experimental circular plane

designed and built by Ron J Feast of Sydney.

The aircraft was evolved from a series of flying models made over a

period of 3 1/2 years. After first building a full size "mock up",construction

began in October, 1997 at Bankstown Airport. Australia hoop pine was

used for the fuselage frame and plywood for the covering.

Each of the main front and rear wings were constructed in one length.

They have curved box SPARS. All the wings are covered with Ceconite

(a polyester fabric) except for the leading edges of the main wings

which are plywood covered.

The engine is ROTAX 912 UL 80 HP. The landing gear was strut

type fitted to the wings and a steerable tail wheel.




Flight tests began at Camden Airport in August, 2000.

The first flight was in July, 2001.

The test pilot was Graham White. Flight tests continued until December, 2001 when it was decided in the interests of good lateral control at the very slow landing speeds of this aircraft to make a number of design changes.

The rear main wing was moved forward to obtain a more compact external shape. Shortened side wings were built. Both main wings were cut at the centre and joined inside the fuselage to obtain a 5° dihedral. A tricycle undercarriage was built consisting of  hardened aluminium leaf springs, coil expansion springs and cables. The nose wheel has a castering action. Ailerons and elevators have streamlined leading edges and increased area.

It was completed in November, 2004.  First taxi tests in February, 2005.
