SAFETY PRECAUTIONS
All of us at Traxxas want you to safely enjoy your new model.
Operate your model sensibly and with care, and it will be exciting,
safe, and fun for you and those around you. Failure to operate your
model in a safe and responsible manner may result in property
damage and serious injury. The precautions outlined in this manual
should be strictly followed to help ensure safe operation. You alone
must see that the instructions are followed and the precautions are
adhered to.
Important Points to Remember
• Your model is not intended for use on public roads or congested
areas where its operation can conflict with or disrupt pedestrian or
vehicular traffic.
• Never, under any circumstances, operate the model in crowds of
people. Your model could cause injury if allowed to collide with
anyone.
• Because your model is controlled by radio, it is subject to radio
interference from many sources that are beyond your control.
Since radio interference can cause momentary losses of radio
control, always allow a safety margin in all directions around the
model in order to prevent collisions.
• The motor, battery, and speed control can become hot during use.
Be careful to avoid getting burned.
• Don't operate your model at night, or anytime your line of sight to
the model may be obstructed or impaired in any way.
• Most importantly, use good common sense at all times.
Speed Control
Your model's electronic speed control (ESC) is an extremely
powerful electronic device capable of delivering high current.
Please closely follow these precautions to prevent damage to the
speed control or other components.
• Disconnect the Battery: Always disconnect the battery from the
speed control when not in use.
• Insulate the Wires: Always insulate exposed wiring with heat
shrink tubing to prevent short circuits.
• 6-7 NiMH cells or 2-3 LiPo cells (2s/3s): The XL-5 HV can accept a
maximum input voltage of 8.4 volts (NiMH) or 11.1 volts (3s LiPo).
Always adhere to the minimum and maximum limitations of the
XL-5 HV as stated in the specifications table.
• Transmitter on First: Switch on your transmitter first before
switching on the speed control to prevent runaways and erratic
performance.
• Don't Get Burned: The ESC and motor can become extremely hot
during use, so be careful not to touch them until they cool. Supply
adequate airflow for cooling.
• Use the Factory-Installed Connectors: Do not change the battery
and motor connectors. Improper wiring can cause fire or damage
to the ESC. Please note that modified speed controls can be
subject to a rewiring fee when returned for service.
• No Reverse Voltage: The ESC is not protected against reverse
polarity voltage.
• No Schottky Diodes: External Schottky diodes are not compatible
with reversing speed controls. Using a Schottky diode with your
Traxxas speed control will damage the ESC and void the 30-day
warranty.
