IMPORTANT NOTES – GENERAL

•  This product is not suitable for children under 16 years of age without the direct supervision of a 

responsible and knowledgeable adult.

•  Carefully read all manufacturers warnings and cautions for any parts used in the construction and use 

of your model.

•  Assemble this kit only in places away from the reach of very small children.

•  First-time builders and users should seek advice from people who have building experience in order to 

assemble the model correctly and to allow the model to reach its performance potential.

•  Exercise care when using tools and sharp instruments.

•  Take care when building, as some parts may have sharp edges.

•  Keep small parts out of reach of small children. Children must not be allowed to put any parts in their 

mouth, or pull vinyl bag over their head.

•  Read and follow instructions supplied with paints and/or cement, if used (not included in kit).

•  Immediately after using your model, do NOT touch equipment on the model such as the motor and 

speed controller, because they generate high temperatures. You may seriously burn yourself seriously 

touching them.

•  Follow the operating instructions for the radio equipment at all times.

•  Do not put fingers or any objects inside rotating and moving parts, as this may cause damage or 

serious injury as your finger, hair, clothes, etc. may get caught.

•  Be sure that your operating frequency is clear before turning on or running your model, and never 

share the same frequency with somebody else at the same time. Ensure that others are aware of the 

operating frequency you are using and when you are using it.

•  Use a transmitter designed for ground use with RC cars. Make sure that no one else is using the same 

frequency as yours in your operating area. Using the same frequency at the same time, whether it is 

driving, flying or sailing, can cause loss of control of the RC model, resulting in a serious accident. 

•  Always turn on your transmitter before you turn on the receiver in the car. Always turn off the receiver 

before turning your transmitter off.
