Prototype UFO-3 10-3518 at Scone, NSW in 2001

 

The UFO series of single-seat light sporting aircraft was designed by David Rowe, an engineer at Scone, NSW, Australia. The aircraft commenced with a sketch he made of a circular shaped aircraft. He then built a model, found this was satisfactory, and built a full-size aircraft fitted with a Rotax 503 engine. This first aircraft, the UFO-2, (10-3213) cruised at 117 km/h (72 mph) and was fitted with a 10 litre (2.19 Imp gal) fuel tank, but this was later changed to a 40 litre (8.8 Imp gal) tank. In late 2001 work commenced to design and build a retractable undercarriage for the UFO-2.

 

 

Later Mr Rowe developed his third design, work on which commenced in May 2000. This was slightly smaller than the second design. The same wingspan was used but the cockpit and engine were moved forward, and a thinner aerofoil was used. Other changes included a pull-start for the engine inside the cockpit, larger fuel tanks, and two small cargo compartments. Whereas the previous designs had been silver overall, the third aircraft was Wild Fire Red.

 

 

No 3 (10-3518), also registered under AUF / RAA Rules, was first shown to the public at the Ultra Light Federation Natfly at Narromine in April 2001 having been flown from Scone in 2.5 hours. Cruising speed of this model is 130 km/h (80 mph).

The UFO is of timber construction with fabric covering. In 2001 work commenced on fitting a retractable undercarriage.
