INTRODUCTION

 IMPORTANT NOTES – ELECTRICAL

•  Insulate any exposed electrical wiring (using heat shrink tubing or electrical tape) 

to  prevent  dangerous  short  circuits.  Take  maximum  care  in  wiring,  connecting 

and  insulating  cables.  Make  sure  cables  are  always  connected  securely.  Check 

connectors for if they become loose. And if so, reconnect them securely. Never use 

R/C models with damaged wires. A damaged wire is extremely dangerous, and can 

cause short-circuits resulting in fire. Please have wires repaired at your local hobby 

shop.

•  Low battery power will result in loss of control. Loss of control can occur due to a 

weak battery in either the transmitter or the receiver. Weak running battery may also 

result in an out of control car if your car‘s receiver power is supplied by the running 

battery. Stop operation immediately if the car starts to slow down.

•  When not using RC model, always disconnect and remove battery. 

•  Do not disassemble battery or cut battery cables. If the running battery short-circuits, 

approximately 300W of electricity can be discharged, leading to fire or burns. Never 

disassemble battery or cut battery cables.

•  Use a recommended charger for the receiver and transmitter batteries and follow 

the  instructions  correctly.  Over-charging,  incorrect  charging,  or  using  inferior 

chargers can cause the batteries to become dangerously hot. Recharge battery when 

necessary. Continual recharging may damage battery and, in the worst case, could 

build up heat leading to fire. If battery becomes extremely hot during recharging, 

please ask your local hobby shop for check and/or repair and/or replacement.

•  Regularly check the charger for potential hazards such as damage to the cable, 

plug,  casing  or  other  defects.  Ensure  that  any  damage  is  rectified  before  using 

the charger again. Modifying the charger may cause short-circuit or overcharging 

leading to a serious accident. Therefore do not modify the charger.

•  Always unplug charger when recharging is finished.

•  Do not recharge battery while battery is still warm. After use, battery retains heat. 

Wait until it cools down before charging. 

•  Do not allow any metal part to short circuit the receiver batteries or other electrical/

electronic device on the model.

•  Immediately stop running if your RC model gets wet as may cause short circuit. 

•  Please dispose of batteries responsibly. Never put batteries into fire.

QUALITY CERTIFICATE

XRAY  MODEL  RACING  CARS  uses  only  the  highest  quality  materials,    the  best 

compounds for molded parts and the most sophisticated manufacturing processes of 

TQM (Total Quality Management). We guarantee that all parts of a newly-purchased 

kit are manufactured with the highest regard to quality. However, due to the many 

factors inherent in model racecar competition, we cannot guarantee any parts once 

you start racing the car. Products which have been worn out, abused, neglected or 

improperly operated will not be covered under warranty. 

We wish you enjoyment of this high-quality and high-performance RC car and wish 

you best success on the track!

In line with our policy of continuous product development, the exact specifications of the kit may vary. In the unlikely event of any 

problems with your new kit, you should contact the model shop where you purchased it, quoting the part number. We do reserve all 

rights to change any specification without prior notice. All rights reserved.

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 www.teamxray.com to get advice, or contact us via 

email at info@teamxray.com, or contact the XRAY distributor in your country.

   IMPORTANT NOTES – NITRO FUEL

• Handle fuel only outdoors. Never handle nitro fuel indoors, or mix nitro fuel in a 

place where ventilation is bad.

• Only use nitro fuel for R/C models. Do not use gasoline or kerosene in R/C models 

as it may cause a fire or explosion, and ruin your engine.

• Nitro fuel is highly inflammable, explosive, and poisonous. Never use fuel indoors 

or in places with open fires and sources of heat. 

• Always keep the fuel container cap tightly shut.

• Always read the warning label on the fuel container for safety information. 

•  Nitro-powered model engines emit poisonous vapors and gasses. These vapors irritate 

eyes and can be highly dangerous to your health. We recommend wearing rubber or vinyl 

gloves to avoid direct contact with nitro fuel.

• Nitro fuel for RC model cars is made of the combination of the methyl alcohol, 

castor or synthetic oil, nitro methane etc. The flammability and volatility of these 

elements is very high, so be very careful during handling and storage of nitro fuel.

• Keep  nitro  fuel  away  from  open  flame,  sources  of  heat,  direct  sunlight,  high 

temperatures, or near batteries.

• Store fuel in a cool, dry, dark, well-ventilated place, away from heating devices, 

open flames, direct sunlight, or batteries. Keep nitro fuel away from children.

• Do not leave the fuel in the carburetor or fuel tank when the model is not in use. 

There is danger that the fuel may leak out.

• Wipe up any spilled fuel with a cloth.

• Be aware of spilled or leaking fuel. Fuel leaks can cause fires or explosions.

• Do  not  dispose  of  fuel  or  empty  fuel  containers  in  a  fire.  There  is  danger  of 

explosion.
