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 is very fast and 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 motors, batteries, 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.

Batteries and Battery Charging

Your model uses rechargeable batteries that must be handled with 
care for safety and long battery life. Make sure to read and follow all 
instructions and precautions that were provided with your battery 
packs and your charger. It is your responsibility to charge and care 
for your battery backs properly. In addition to your battery and 
charger instructions, here are some more tips to keep in mind.

  Never leave batteries to charge unattended.
  Remove the batteries from the model while charging.
  Always unplug the batteries from the electronic speed control 

when the model is not in use and when it is being stored  
or transported.

  Allow the battery packs to cool off between runs  

(before charging).

  Do not use battery packs that have been damaged in any way.

  Do not use battery packs that have damaged wiring, exposed 

wiring, or a damaged connector. 

  Children should have responsible adult supervision when 

charging and handling batteries.

Speed Control

  Disconnect the Batteries: Always disconnect the batteries from the 

speed control when not in use. 

  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 heat sink can get extremely hot, so be 

careful not to touch it until it is cool. Supply adequate airflow  
for cooling.

  Use Stock Connectors: If you decide to change the battery  

or motor connectors, only change one battery or motor connector 
at a time. This will prevent damage from accidentally mis-wiring 
the speed control. Please note that modified speed controls can 
be subject to a rewiring fee when returned for service. Removing 
the battery connector on the speed control or using connectors 
with no reverse-polarity protection on the speed control will void 
the product’s warranty.

  Insulate the Wires: Always insulate exposed or damaged wiring 

with heat shrink tubing to prevent short circuits

  Always Use Heat Sinks: Three heat sinks are factory-installed on 

the speed control and must be used for maximum cooling and 
performance. 

  No Reverse Voltage: The speed control is not protected against 

reverse polarity voltage. When changing the battery and/or 
motor, be sure to install the same type of connectors to avoid 
reverse polarity damage to the speed control. Removing the 
battery connectors on the speed control or using the same-gender 
connectors on the speed control will void the product’s warranty.

  Do Not Let the Transistor Tabs Touch: Never allow the three 

separate transistor banks to touch each other or any exposed 
metal. This will create a short circuit and damage the speed 
control. (For example, laying a metal tool across the heat sinks can 
damage the speed control.)

  No Schottky Diodes: External Schottky diodes are not compatible 

with reversing speed controls. Using a Schottky diode with the 
EVX-2 will damage the ESC and void the 30-day warranty.
