Composite-ARF kangaroo, Инструкция по эксплуатации

Before you start building the model:
If you are buying a radio control system for this model, check that the transmitter and receiver are suitable for
model aircraft and bear the standard type-approval sticker.
The frequency bands used for radio control systems are shared by other radio equipment and radio-frequency
apparatus, so we cannot guarantee that you will not suffer interference when using your system.
During construction
Adhesives and paints contain solvents which may be hazardous to health under certain circumstances. Read and
observe the notes and warnings supplied by the manufacturer of these materials. Take waste glue and paint back
to the model shop for disposal, or to your local toxic waste collection centre.
Take care to keep tools, adhesives and paints out of the reach of children.
A large, unobstructed working surface is a great advantage for all types of model-making.
Essential tools for building the KANGAROO:
This high-quality model is of all-glass construction, so completing it is really just a matter of assembly work.
The model is designed as standard to accept a retractable undercarriage, and mounts for standard commercial
retract units are already bonded in place. However, you will soon see that the underside of the fuselage is not cut
away for the retracts; you will only find guide lines scored in the moulding, and these apply only to our
recommended retract units. There are good reasons for this: if a customer already owns a suitable set of retracts,
then factory-cut openings would not necessary fit, and the same applies if you prefer to fit a make of retracts
other than those we recommend. That is why we only provide approximate guide lines. Cutting the openings and
installing the retract units is not necessarily a straightforward task, and calls for careful thought and accurate
working to avoid mistakes. In fact, installing the retracts is the most complex and difficult part of construction.
However, the type of modeller for whom the Kangaroo is intended will not find this difficult.
A well-equipped model workshop with all the usual machines and tools is a fundamental requirement for anyone
wishing to become a jet pilot. However, that does not mean that a milling machine, lathe and other engineering
tools and facilities are inevitably required.
Gluing different materials
The table below shows the correct glue to use for various typical joints in the model. It is just a guideline, and is
not intended to be comprehensive.
All glued joints must be carried out with great care, and this applies in particular to gluing the control surface
horns in place, and fixing the plates which support the RC system and turbine components, together with the
formers, mounting plates and rails associated with them. For these important joints we recommend epoxy
laminating resin and a suitable thickening agent such as chopped cotton, 5-minute epoxy, or thin / thick cyano
used with activator spray. Provided that the GRP surfaces of the KANGAROO’s components are roughened
thoroughly, it is possible to make such joints safely using thick CA and accellerator spray. CA does not attack
the material used as the filler in the GRP sandwich, and is also safe with the foam used for the formers (Herex);
it produces really strong joints with these materials. These joints are usually stronger than the Herex / sandwich
material itself. However, it is important that all formers and other internal parts which are glued in place with CA
should be a really accurate fit. Bear in mind that it is not possible to adjust their position once the glue has been
applied, as is possible when using epoxy resin or 5-minute epoxy. The net result is this: if you are a very
confident builder, use CA. If you are less experienced or “not so quick”, use epoxy laminating resin or 5-minute
epoxy to be on the safe side.
Please note: you must not use CA for the control surface linkage joints - gluing the GRP or phenolic horns in the
machined slots in the wing and stabiliser control surfaces.
