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 vi-
bration, 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.
• This helicopter is designed to be operated by adults, although young people of 16
years or more may do so under the instruction and supervision of competent adults.
• The model features sharp points and edges which may cause injury.
• Controlling a model helicopter successfully is not easy; you will need persistence and
determination to learn the skills, and good hand-eye co-ordination is a basic require-
ment.
• Before you attempt to fly the model you should study the subject of helicopters in
depth, so that you have a basic understanding of how the machines work. Read every-
thing you can on the theory of helicopters, and spend as much time as you can watch-
ing other model helicopter pilots flying. Talk to chopper pilots, ask their advice, and
enrol at a specialist model flying school if you need to. Many model shops will also be
prepared to help you.
• Please be sure to read right through these instructions before you start operation of
the model. It is important that you clearly understand the complete procedure before
you begin flying.
• Don't make modifications to the model's construction by using parts other than those
specifically recommended, unless you are certain of the quality and suitability of these
other parts for the task.
• We have made every effort to point out to you the dangers inherent in operating this
model helicopter. Since neither we, the manufacturer, nor the model shop that sold
you the kit have any influence over the way you build and operate your model, we are
obliged to disclaim any liability in connection with it.
