Precautions before use
LOCATE AN APPROPRIATE LOCATION
To ensure the safety of yourself, others and your model, do not fly near
airports, buildings, roads, crowded areas or high-voltage cables. R/C
helicopters can fly at high speed and have rotor blades spinning at high RPM,
thus posing a certain degree of potential danger during operation. Choose a
legal and safe flying field consisting of flat, smooth ground without
obstacles, other people, animals etc. For the first flights, please choose a
legal flying field with ample clear space. Flying over long grass reduces
damage in the event of a crash. Consider the use of a training landing gear.
Do not fly your model in inclement weather, such as rain, wind, snow or
darkness.
PREVENT MOISTURE
R/C models are composed of many precision mechanical and electrical
components. It is critical to keep the model and associated equipment away
from moisture and other contaminants. The introduction or exposure to water or
moisture in any form can cause the model to malfunction, resulting in loss of
control or a crash. Do not operate or expose the model to rain or moisture.
MALOPERATION
Please use only genuine replacement parts listed in the manual to ensure
correct operation. Use of non-standard or damaged parts voids the product
warranty and may cause danger. This product is designed for leisure R/C
modelling, do not use the model for other purposes.
WARNING OBTAIN THE ASSISTANCE OF AN EXPERIENCED PILOT.
Before turning on your model and transmitter, check with other RC model users
in the area that it is safe to fly. For inexperienced pilots, the guidance
provided by an experienced pilot can be invaluable for the assembly, setup,
tuning, trimming and first flight. (It is recommended to practice with a
computer-based flight simulator beforehand.)
WARNING SAFE OPERATION.
Operate this helicopter to your ability. Do not fly under the influence of
perception-altering substances, as well as when you’re sleep-deprived. It may
result in danger or injury.
CAUTION ALWAYS BE AWARE OF THE ROTATING BLADES.
During the operation of the helicopter, the main rotor and tail rotor will be
spinning at very high rotation speeds. Rotor blades are capable of inflicting
serious to lethal bodily injury and damage to the environment. Be conscious of
the hazards posed by the spinning rotor blades and maintain a safe distance
from the helicopter at all times. Always fly the model a safe distance from
yourself and others,as well as your surroundings. Never take your eyes off the
model or leave it unattended while it is turned on. Immediately turn off the
model and transmitter and remove the battery after you have landed the model.
CAUTION KEEP AWAY FROM HEAT.
R/C models are made of various forms of plastics. Plastic is very susceptible
to damage or deformation due to extreme heat and cold. Make sure not to store
the model near any source of heat, such as direct, strong sunlight or a
heater. It is best to store the model indoors, in a climate-controlled, room-
temperature environment.
