Avro-Duigan 1911 |
Back to top
|
 In 1911, John
Duigan went to England and ordered a plane from Avro to his own specifications. The result was the Avro-Duigan. Avro subsequently developed this aeroplane into the Avro 500 which was the immediate
predecessor of the famous Avro 504.The plan presented here is for a 635mm (25") span free flight model powered by a KP-01 electric motor. |

Bristol M1C (Gypsy Powered) Racer |
Back to top
|
 The M1C was
designed by Bristol Aircraft in the UK as a WWI fighter, and two were imported to Australia by Harry Butler. One was modified for racing by Horrie Miller, with a Gypsy inline engine, and a slimmer
fuselage.
 The plan is for a simplified model to the "neo Dime Scale" rules of the Flying
Aces Club (FAC). Several models have been constructed from this plan, including Kevin Mooney's version, shown in the picture.

CAC CA-2 Wackett Trainer (prototype version) |
Back to top
|
 As World War II
loomed on the horizon, Australia needed a training aircraft to train the new generation of pilots who would soon be needed. So the Wackett was developed to meet this need. The two prototypes featured
in-line Gypsy engines, but these turned out to be underpowered. But they still make a good subject for free flight scale model.
The plans are drawn for a 406mm (16") span "Pseudo Dime Scale" model of the Wackett prototype for rubber power. Plan prints on 2 pages. |

CAC CA-6 Wackett Trainer (production version) |
Back to top
|
 The solution to the
under-powered state of the CA-2 prototypes was to install a Warner Scarab radial engine.
In this new form, the Wackett met the requirements of the RAAF trainer specification, and 200 Wacketts were constructed and saw service with the RAAF and the Dutch East Indies
Air Force (now Indonesia).
The plans are drawn for a 406mm (16") span "Pseudo Dime Scale" model of the Wackett for rubber power. Plan prints on 2 pages.

CAC CA-15 "Kangaroo" |

 The CA-15 was a
prototype fighter developed in the closing stages of WWII. It represented the peak in piston-powered performance.
I've presented plans at two different sizes (see at right), showing all formers, ribs and other templates. I'm currently building this one at the moment (at 24" span), so construction details are being added as I
progress... |

CAC CA-23 Ceres |
Back to top
|
 The Ceres was
developed by CAC in the 1950's as an agricultural aircraft for top-dressing. It was a new design, but utilised some components from surplus Wirraway trainers.
It was a larger, heavier and more powerful aircraft compared to the Wirraway. The pilot was seated in a raised cockpit (in a similar location to the rear seat of the Wirraway)
aft of the hopper for an improved view. The landing gear was fixed. Large slotted flaps were fitted as were fixed leading edge slats on the outboard wing panels.
The plans are drawn for a 610mm (24") span scale model of the Ceres for rubber power (prints out on 6 sheets of paper).

 After
venturing to England and working with Avro, John Duigan returned to Australia and built a second tractor biplane in his backyard in suburban Melbourne in 1913.

 Australia has
always been one of the world's largest agricultural producers, and this has fueled the demand for agricultural aircraft. The KS.1 was a post WWII conversion of the Wackett
trainer for top-dressing and spraying - by replacing the front cockpit with a hopper.
The plan is for a ½" scale (1:24) rubber powered model of 470mm (18.5") span.

 The SC1 was a prototype for a 4-place trainer or tourer. It first flew in 1962, but never went into production due to competition from imported trainer aircraft.
The sole prototype is now being restored at the Museum of Army Aviation in Oakey, Queensland (on loan from the Australian National Aviation Museum at Moorabbin airport in Melbourne).
 This plan is for a 520mm (20.5") span rubber powered model. The plan prints out on several pages. It includes templates for "do it yourself" printwood. |

Bellanca YO-50 |

 The Bellanca YO-50 was
developed in the early 1940's as an observation and liason aircraft for the US army. 3 prototypes were built and tested, however the Army opted for smaller, simpler liason aircraft (such as the Piper
L-3 and Stinson L-2). So the YO-50 never went into production. It was a large aircraft, designed for high visibility and STOL performance.

The Auster Mk III was developed by Taylorcraft Aeroplanes (England)
during the Second World War as an observation platform for artillery spotting. It was also adopted for communications roles. Many Mk III aircraft made their way to Australia, and the Mk III was also
assembled Down Under.
