R/C HELICOPTER SAFETY
A radio-controlled model helicopter is a technically complex device that must be built and operated with care. It is
also a fascinating and challenging part of the R/C Sport, the mastery of which is very rewarding.
A model helicopter must be built exactly in accordance with the building instructions. The kit manufacturer has spent
much time and effort refining his product to make it reliable in operation and easy to build. The essentially bolt-
together construction can proceed quite rapidly, giving the builder a strong sense of accomplishment that encourages
hasty progress from one construction phase to the next, so that the completed model can be more quickly seen and
enjoyed. It is essential to recognize and guard against this tendency. Follow building instructions exactly. Use only
original parts B even single screws B and consider no alterations. Vibration and stress levels are high and all fasteners
and attachments must be secure for safety in operation.
Note that this is the first use of the word SAFETY in these comments. Previously the kit manufacturer=s efforts to
ensure RELIABLE operation were mentioned. That is ALL that he can do. Safe operation is the responsibility of the
builder/flyer and starts with careful construction and continues with selection and installation of reliable radio
equipment, engine, and fuel system, and the proper use of starters and other support equipment.
The need for safety is nowhere greater than at the flying field. A number of guidelines for safe flight have been
developed by experienced flyers and are set down here. It is urged that they be read, understood and followed.
GUIDELINES FOR SAFE R/C HELICOPTER FLIGHT
Fly only at approved flying fields and obey field regulations.
Follow frequency control procedures. Interference can be dangerous to all.
Know your radio. Check all transmitter functions before each flight.
Be aware that rotating blades are very dangerous and can cause serious injury. Always hold the rotor head while
starting the engine and do not release until at the take off point.
Never fly near or above spectators or other modelers.
If a beginner, get help trimming the model, and flight training later.
Don=t Atrack@ the main blades while holding the tail boom. This is a temptation to builders who cannot hover yet and is
very dangerous.
Follow all recommended maintenance procedures for model, radio, and engine.
WARNING
This helicopter is not a toy, but a complex flying machine that must be assembled with care by a responsible
individual. Failure to exert care in assembly, or radio or accessory installation, may result in a model incapable
of safe flight or ground operation. Rotating components are an ever-present danger and source of injury to
operators and spectators. Since the manufacturer and his agents have no control over the proper assembly and
operation of his products, no responsibility or liability can be assumed for their use.
