 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 RC 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.

or imply how long any model cars‘ components or electronic components will 

last before requiring replacement.

Due  to  the  high  performance  level  of  this  model  car  you  will  need  to 

periodically  maintain  and  replace  consumable  components.  Any  and  all 

warranty  coverage  will  not  cover  replacement  of  any  part  or  component

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. Warranty will not cover components 

that are considered consumable on RC vehicles. XRAY does not pay nor refund 

shipping on any component sent to XRAY or its distributors for warranty. XRAY 

reserves the right to make the final determination of the warranty status of

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.
