operating RC model racing cars. This is not a toy; it is a precision car model. This model racing car is not intended for use by beginners, 

inexperienced customers, or by children without direct supervision of a responsible, knowledgeable adult. If you do not fulfill these

operating your M18 PRO, YOU MUST read through all of the operating instructions and instruction manual and fully understand them to get 

the maximum enjoyment and prevent unnecessary damage. Read carefully and fully understand the instructions before beginning assembly.

Make sure you review this entire manual, the included engine instructions, and examine all details carefully. If for some reason you decide the M18 

PRO is not what you wanted or expected, do not continue any further. Your hobby dealer cannot accept your M18 PRO kit for return or exchange 

after it has been partially or fully assembled.

             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 engine and muffl er, 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 fi ngers or any objects inside rotating and moving parts, as this may cause damage or serious injury as your fi nger, 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, fl ying 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 confl ict with or disrupt pedestrian or vehicular traffi c.
•  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.

R/C & BUILDING TIPS

• Make sure all fasteners are properly tightened. Check them periodically.

• Make sure that chassis screws do not protrude from the chassis.

• For the best performance, it is very important that great care is taken to ensure the free movement of all parts.

• Clean all ball-bearings so they move very easily and freely.

• Tap or pre-thread the plastic parts when threading screws.

• Self-tapping screws cut threads into the parts when being tightened. Do not use excessive force when tightening the self-tapping screws because 

you may strip out the thread in the plastic. We recommended you stop tightening a screw when you feel some resistance.

• Ask your local hobby shop for any advice.

Please support your local hobby shop. We at XRAY Model Racing Cars support all local hobby dealers. Therefore we ask you, if at all possible, to 

purchase XRAY products at your hobby dealer and give them your support like we do. If you have difficulty finding XRAY products, please check out
