General notes regarding construction and the radio con-
trol system:
The building instructions are divided into sub-assemblies,
each of which is sub-divided into individual stages arranged
in a logical sequence. All the sub-assemblies are numbered.
Each stage is accompanied by an assembly drawing which
clarifies the procedures involved. To help you identify the
correct items, each assembly drawing also includes a full-
size representation of the screws, washers and shim was-
hers required for that stage.
Each stage also includes
supplementary Hints and Tips
which apply to the procedures currently in hand.
All the pushrod lengths and servo output arm lengths stated
in the building instructions assume the use of robbe /
Futaba servos.
If you wish to use other makes or types of servo, these
dimensions may need to be altered slightly.
Please see the separate accessory sheet for details of the
tools and accessories required to complete and operate
the model.
Keep all the supplementary sheets and these building
instructions in a safe place, in case you need to carry out
repairs or re-assembly work later. We recommend that you
also keep all the supplementary sheets supplied in the kit.
If you have a complaint or wish to make a claim under gua-
rantee, please note that it is essential to state the Check
Number and provide proof of purchase (receipt).
Notes on building the model:
Three different symbols are used repeatedly throughout
these instructions:
1: Cyano-acrylate glue (“cyano”)
-
Use cyano for these joints.
2: Grease tube
-
Use grease (robbe No. 5532) at these points.
3: Loctite
-
Use Loctite medium-strength thread-lock fluid
(robbe No. 5074) at these points.
It is essential to de-grease the screw threads before apply-
ing thread-lock fluid.
Tip:
Loctite should always be used very sparingly, otherwi-
se excess fluid may run into ballraces and plain bearings
and jam them. It is often best to apply the fluid into the
threaded hole itself.

The stated paint quantities are approximate figures; more or
less may be required according to your preferred method of
application.
Most modellers will wish to paint the vehicle in the colour
scheme of their choice.
We therefore recommend that you start by assembling the
complete basic vehicle, as this will allow you to decide
which parts are to be painted, and in which colours. You can
then remove these parts, paint them, and only then install
them permanently. This applies in particular to parts which
have to be glued in place.
The model is designed in such a way that most components
can be removed at any time. This makes it possible to chan-
ge the vehicle’s configuration and radio installation when
you wish to do so.
Stage 1, installing the servos and the leaf-springs
Tip:
most makes of servo are fitted with a splined output
shaft.
By repeatedly rotating the output disc through approxima-
tely 90° it is normally possible to find a position where the
output disc is more or less exactly perpendicular to the
servo case sides.
The raised lines on the output discs will help you orientate
them correctly.
It is not absolutely essential to fit the user-prepared out-
put discs as shown, but they do alleviate the problem of
unwanted differential travels which can result when a con-
