Precautions before use

FORBIDDEN
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 duringoperation. 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. FORBIDDEN
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 moisturein 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. FORBIDDEN
MALOPERATION
Please use only genuine replacement parts listed in the manual to ensure correct operation. Use of non-standard or damaged parts voids theproduct 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 firstflight. (It is recommend to practice with computer-based flight simulator beforehand.) WARNING
SAFE OPERATION
Operate this helicopter within your ability. Do not fly under the influence of perception-altering substances, as well as when you’re sleep deprived. Itmay result in danger or injury. CAUTION
During the operation of the helicopter, the main rotor and tail rotor will be spinning at very high rotation speeds. Rotor blades are capable ofinflicting serious to lethal bodily injury and damage to the environment. Be conscious of the hazards posed by the spinning rotor blades andmaintain 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 itunattended while it is turned on. Immediately turn off the model and transmitter and remove 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 tostore 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.
