We all want you to have many hours of pleasure in

our mutual hobby of modelling, and safety is an im-

portant aspect of this. It is absolutely essential that

you read right through these instructions and take ca-

reful note of all our safety recommendations.

If you are a beginner to the world of radio-controlled

model aircraft, boats and cars, we strongly advise

that you seek out an experienced modeller in your

ﬁ eld and ask him for help and advice.

These instructions must be passed to the new owner

if you ever sell the equipment.

Application

This radio control system may only be used for the

purpose for which the manufacturer designed it, i.e.

for operating radio-controlled models which do not

carry humans. No other type of use is approved or

permissible.

Safety notes

SAFETY IS NO ACCIDENT

and …

RADIO-CONTROLLED MODELS ARE NOT

PLAYTHINGS

… because even small models can cause serious

personal injury and damage to property if they are

handled incompetently.

Technical problems in electrical and mechanical sys-

tems can cause motors to rev up or burst into life un-

expectedly, with the result that parts may ﬂ y off at gre-

at speed, causing considerable injury.

Please take every possible care to avoid short-circuits

of all types. “Shorts” can easily destroy parts of the

radio control system, but the stored energy in the bat-

tery constitutes an even more serious danger: in un-

favourable circumstances there is a serious risk of ﬁ re

and even explosion.

Propellers, helicopter rotors and all other rotating

parts which are driven by a motor or engine represent

a permanent injury hazard. Do not touch these items

with any object or part of your body. Remember that

a propeller spinning at high speed can easily slice off

a ﬁ nger. Never stand in the primary danger zone, i.e.

in the rotational plane of the propeller or other rota-

ting parts.

When an electric ﬂ ight or drive battery is connected

to the power system, never touch or even come close

to the propeller or propellers!

When you are programming the transmitter it is im-

portant to avoid the risk of an electric motor or I.C. en-

gine bursting into life unexpectedly. The best course is

to disconnect the fuel supply or the ﬂ ight / drive batte-

ry before carrying out any work.

Protect all electronic equipment from dust, dirt, damp,

vibration and foreign bodies. Avoid subjecting the

equipment to excessive heat or cold. Radio control

equipment should only be used in “normal” ambient

temperatures, i.e. within the range -15°C to +55°C.

Avoid subjecting the radio control system to shock

and pressure. Check the units at regular intervals for

damage to cases and leads. Do not re-use any item

which is damaged or has become wet, even after you

have dried it out thoroughly.

Use only those components and accessories which

we expressly recommend. Be sure to use only genui-

ne matching GRAUPNER connectors of the same de-

sign with contacts of the same material. Insofar as

they are still required, use only genuine GRAUPNER

plug-in crystals on the appropriate frequency band.

When deploying cables, note that they must not be

under tension, and should never be bent tightly or kin-

ked, otherwise they may fracture. Avoid sharp edges

which could wear through the cable insulation.

Check that all connectors are pushed home ﬁ rmly be-

fore using the system. When disconnecting compon-

ents, pull on the connectors themselves – not on the

wires.

It is not permissible to carry out any modiﬁ cations

to the RC system components. Avoid reverse polari-

ty and short-circuits of all kinds involving the connec-

ting leads, as the equipment is not protected against

such errors.

Installing the receiving system and deploying the

receiver aerial

In a model aircraft the receiver must be packed in soft

foam and stowed behind a stout bulkhead, and in a

model boat or car should be protected effectively from

dust and spray.

The receiver must not make contact with the fusela-

ge, hull or chassis at any point, otherwise motor vib-

ration and landing shocks will be transmitted direct-

ly to it.

When installing the receiving system in a model with

a glowplug or petrol engine, be sure to install all the

components in well protected positions so that no ex-

haust gas or oil residues can reach the units and get

inside them. This applies above all to the ON / OFF

switch, which is usually installed in the outer skin of

the model.

Secure the receiver in such a way that the aerial, ser-

vo leads and switch harness are not under any strain.

The receiver aerial is permanently attached to the re-

ceiver. It is about 100 cm long and must not be shor-

tened or extended. The aerial should be routed as far

away as possible from electric motors, servos, metal

pushrods and high-current cables. However, it is best

not to deploy the aerial in an exactly straight line, but

to angle it: e.g. run it straight to the tailplane, then lea-

ve the ﬁ nal 10 - 15 cm trailing loosely, as this helps

to avoid reception “blind spots” when the model is in

the air. If this is not feasible, we recommend that you

lay out part of the aerial wire in an S-shape inside the

model, close to the receiver if possible.

Installing the servos

Always install servos using the vibration-damping

grommets supplied. The rubber grommets provide

some degree of protection from mechanical shocks

and severe vibration.
