 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.

•  Keep the wheels of the model off the ground when checking the operation 

of the radio equipment.

•  Disconnect the battery pack before storing your model.

•  When learning to operate your model, go to an area that has no obstacles 

that can damage your model if your model suffers a collision.

•  Remove  any  sand,  mud,  dirt,  grass  or  water  before  putting  your  model 

away.

•  If  the  model  behaves  strangely,  immediately  stop  the  model,  check  and 

clear the problem.

•  To  prevent  any  serious  personal  injury  and/or  damage  to  property,  be 

responsible when operating all remote controlled models.

•  The model car is not intended for use on public places and roads or areas 

where its operation can conflict with or disrupt pedestrian or vehicular traffic.

•  Because  the  model  car  is  controlled  by  radio,  it  is  subject  to  radio 

interference from many sources that are beyond your control. Since radio 

interference  can  cause  momentary  loss  of  control,  always  allow  a  safety 

margin in all directions around the model in order to prevent collisions.

•  Do not use your model:

  - Near real cars, animals, or people that are unaware that an RC car is being   

  driven.

  - In places where children and people gather

  - In residential districts and parks

  - In limited indoor spaces

  - In wet conditions

  - In the street

  - In  areas  where  loud  noises  can  disturb  others,  such  as  hospitals  and  

   residential areas.

  - At night or anytime your line of sight to the model may be obstructed or  

   impaired in any way.

To prevent any serious personal injury and/or damage to property, please be

responsible when operating all remote controlled models.
