请于自己能力内及需要一定技术范围内操作这台直升机，过于疲劳，精神不佳或不当操作，意外发生风险将可能会提高。
Operate this helicopter within 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.
ALWAYS BE AWARE OF THE ROTATING BLADES 远离运转中的零件
SAFE OPERATION 安全操作
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.
KEEP AWAY FROM HEAT 远离热源
遥控飞机多半是以 纤维或聚乙烯、电子商品为主要材质，因此要尽量远离热源、日照、以避免因高温而变形甚至熔毁损坏的可能。
当直升机主旋翼与尾旋翼运转时，切勿触摸并远离任何物件，以避免造成危险及损坏。
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 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 battery after you have landed the model.
避免独自操控
至飞行场地前，需确认是否有相同频率的同好正在飞行，因为开启相同的频率的发射机将导致自己与他人立即干扰等意外危险。
For inexperienced pilots, the guidance provided by an experienced pilot can be invaluable for the assembly, setup, tuning, trimming and first
flight. (It is recommend to practice with computer-based flight simulator beforehand.)
Before turning on your model and transmitter, check with other RC model users in the area that it is safe to fly .
OBTAIN THE ASSISTANCE OF AN EXPERIENCED PILOT
遥控飞机操控技巧在学习初期有着一定的难度，要尽量避免独自操作飞行，需有经验的人士在旁指导，才可以操控飞行。 勤练电脑模拟器及
老手指导是入门必要的选择
请确认于产品限界内操作，请勿过载使用，并勿用于安全、法令外其他非法用途。
MALOPERATION 勿不当使用本产品
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 .
请勿自行改造加工，任何的升级改装或维修，请使用三源电子科技产品目录中的零件，以确保结构的安全。
直升机内部也是由精密的电子零件组成，所以必须绝对的防止潮湿或水气 避免在浴室或雨天时使用，防止水气进入机身内部而导致机件及电
子零件故障而引发不可预期的意外！
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.
R/C models are composed of many precision mechanical and electrical components.
PREVENT MOISTURE 远离潮湿环境
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.
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.
初次练习时，务必选择在空旷合法专属飞行场地并适当搭配练习架飞行，这对于飞行失误所造成的损伤将会大幅的降低。请勿在下雨天、打雷
等恶劣天气下操作，以确保本身及机体的安全。
必须注意周边有没有人、高楼、建筑物、高压电线、树木等等、避免操控的不当造成自己或与他人的财产损坏。
LOCATE AN APPROPRIATE LOCATION 远离障碍物及人群
To ensure the safety of yourself, others and your model, do not fly near airports, buildings, roads, crowded areas or high voltage cables.
直升机飞行时具有一定的速度，相对的也潜在着危险性，场地的选择也相对的重要，请遵守当地的法律法规到合法的遥控飞行场地去飞行。
