History:
Designed by Rimn Isaminskas, an aeronautical engineer in Los Angeles, California, USA, the Jungster series of light aircraft was simple and strong, the Jungster I being an aerobatic biplane. The design was based on the German wartime aerobatic training biplane, the Bucker Jungmeister.
Designed in 1962 and built to 80 per cent scale, the fuselage was built of Sitka spruce, with fittings of 4130 steel, covered with fabric. The wings were spruce and plywood with internal bracing.
The Jungster became available in two variants, the Jungster I biplane and the Jungster 2 monoplane. It was said to have similar flying qualities to the original Jungmeister. The Jungster I has also been known as the Jungster Papoose RK-1.
The type was usually fitted with a Lycoming O-235 engine or O-290 engine but engines in the 63 kw to 112 kw (85 hp to 150 hp) range could be installed. In later years a couple of builders overseas considered installing the Australian-manufactured Rotec R-2800 radial engine to make the aircraft look more similar to the original trainer.
Kits have not been available and only plans have been supplied to builders by K & S Supply Company of Alberta, Canada.
At least one example has been completed in Australia and registered under Recreational Aviation Australia (RAA) Regulations. This aircraft was built by Wayne Holden, who has also completed a scale replica of a Fokker Dr.1 with a Rotec radial engine, and a scale Hawker Hurricane.
An example has been completed in New Zealand as ZK-DDA² (c/n DRP1 – ex N701D), this being registered as a Papoose RK-1 Jungster on 22 August 2017.
