 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.

all which may cause premature wear or failure of any component. XRAY has no 

control over usage of vehicles once they leave the dealer, therefore XRAY can only

maintain and replace consumable components. Any and all warranty coverage will 

not cover replacement of any part or component damaged by neglect, abuse, or 

improper  or  unreasonable  use.  This  includes  but  is  not  limited  to  damage  from 

crashing,  chemical  and/or  water  damage,  excessive  moisture,  improper  or  no 

maintenance, or user modifications which compromise the integrity of components.

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.
