Warning notes

• 

• 

• 

• 

The contents of this kit can be assembled to produce a working model, but the model

is by no means a harmless plaything. If assembled incorrectly or handled incompe-

tently or carelessly it can cause serious injury to persons and damage to property.

• 

• 

• 

• 

When the model helicopter’s motor is running, the two rotors are spinning at high

speed and contain an enormous quantity of rotational energy. Anything and every-

thing that gets into the rotational plane of the rotors is either damaged or destroyed -

and that includes parts of your body. Please take extreme care at all times with this

machine.

• 

• 

• 

• 

If any object obstructs the rotational plane of the revolving rotors, severe damage will

probably be caused to the rotor blades as well as the object. Broken parts may fly off

and result in enormous imbalance; the whole helicopter then falls into sympathetic

vibration, you lose control and have no way of predicting what the model will do next.

• 

• 

• 

• 

You may also lose control if a problem arises in the radio control system, perhaps as

a result of outside interference, component failure or flat or faulty batteries, but in any

case the result is the same: the model helicopter’s response is entirely unpredictable.

Without prior warning it may move off in any direction.

• 

• 

• 

• 

Helicopters have many parts which are naturally subject to wear, including gearbox

components, motor, ball-links etc., and as a result it is absolutely essential to check

and maintain the model regularly. It is standard practice with full-size aircraft to give

the machine a thorough "pre-flight check" before every flight, and this is equally im-

portant with your model helicopter. Constant checking gives you the opportunity to

detect and correct any faults which may develop before they are serious enough to

cause a crash.

• 

• 

• 

• 

The kit also includes two further information sheets - SHW 3 and SHW 7 - which in-

clude safety notes and warnings. Please be sure to read them and keep to our rec-

ommendations. They are an essential part of these instructions.

• 

• 

• 

• 

This helicopter is designed to be constructed and operated by adults, although young

people of 16 years or more may do so under the instruction and supervision of com-

petent adults.

• 

• 

• 

• 

The model features sharp points and edges which may cause injury.

• 

• 

• 

• 

Flying model aircraft is subject to certain legal restrictions, and these must be ob-

served at all times. For example, it is essential to take out third party insurance, you

must obtain permission to use the flying site, and you may have to obtain a licence to

use your radio control system (regulations vary from country to country).

• 

• 

• 

• 

It is important to transport your model helicopter (e.g. to the flying site) in such a way

that there is no danger of damaging the machine. Particularly vulnerable areas are the

rotor head linkages and the tail rotor generally.
