Product informations

The AGUSTA A119 »KOALA« is a single-turbine helicopter designed for a wide range of tasks. It is largely based on the familiar twin-engined A109, but is fitted with only one Pratt & Whitney PT6B-37A turbine, with a take-off power of 1002 BHP and a continuous output of 872 BHP, while as a “workhorse helicopter” it features a robust skid landing gear. In the EMS (air rescue) helicopter version the cabin provides spacefor two stretchers. The prototype on which our model is based is an Australian rescue helicopter belonging to its operator, »CareFlight«, which is stationed in Orange, New South Wales. This machine was the first EMS version of the »KOALA«. The model is drawn up to a scale of 5.8:1 and features a rotor diameter of 186 cm when fitted with the scale four-blade rotor head. The machine is designed to accommodate the proven GRAUPNER/JetCat helicopter mechanics; in this version theturbine exhaust exits the right-hand side of the fuselage via a short, angled duct. Alternatively the fuselage can be fitted with GRAUPNER/Heim UNI-MECHANICS 2000. The white-pigmented GRP fuselage is supplied with most of the window openings and other apertures pre-cut. Excellent access to the mechanics and internal fittings is granted by the large, divided upper fairing and the side doors, which are completely removable; the doors conceal the fueltank and gas tank filler fittings for the engine starting procedure. The mechanics complete with servos and auxiliary equipment are installed in the fuselage from above as a single unit, and connected to it by means of two profiled aluminium rails. The tail rotor drive system is based on a 2 mm Ø spring steel shaft, supported in Teflon bushes in a 10 mm Ø aluminium tube. The shaft is connected to the tail rotor gearbox by means of the coupling sleeve (supplied); the tail rotor gearbox and drive shaft therefore form a single unit which can be withdrawn to the rear out of the fuselage. The tail rotor control linkage is based on a CFRP pushrod. Like the main fuselage, the upper fuselage fairing, the tail cone, the horizontal stabiliser panels and the side doors are moulded in GRP, and feature a high-quality gloss white surface finish. If the self-adhesive decals are used, there is no need to paint the model overall. The sliding doors fit in integral recesses moulded into the fuselage. The vacuum-moulded windows feature recessed flanges, and are designed to be glued in the machined openings in the fuselage shell from the inside. This process may require slight trimming of the pre-cut openings, but the result is a model with a highly impressive scale appearance.
