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!

Please note that raw materials such as aluminum, steel, brass, fibreglass, or carbon fibre may 

have small scratches on the surface which is a standard characteristic of any raw material. 

Scratches on the surface of any materials are NOT considered to be material defects.

Products may potentially have small amounts of corrosion on them.  This may be caused by variances in 

weather during different times of the year, humidity in the shop or during shipping, and other contributing 

factors. Even though we have taken all precautions and protection methods to prevent corrosion, these small 

amounts of corrosion (if present) are unavoidable and considered to be acceptable.

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

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.
