Xray XB4, Instruction Manual

 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 fi re.  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 fi re 
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 fi re. 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 rectifi ed 
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 fi nished.
•  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 fi re.

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.
