Radio system does not work properly:
If the power light on the transmitter does not come on, check
for proper battery installation and that the batteries are new
and/or fully charged. If the power light is blinking, then the
transmitter batteries are weak and should be replaced. See
page 13 for more details.
If the transmitter light is on but the radio is still not
responding, check for proper installation of batteries in the
model and that the batteries are new and/or fully charged.
Check to make sure the on/off switch on the model is in the
on position. Check for damaged wires, a loose crystal, or loose
connections. See page 14 for more details.
Short radio range:
If the radio range appears short, then first check to make sure
the transmitter antenna is fully extended and that the
antenna in the E- is in place and has not been cut or
damaged. Next, make sure the batteries are all fully charged.
Finally, if you are still experiencing short range, try a different
location. Sometimes there can be interference from various
sources that can cause your radio to malfunction.
Steering channel works but the motors will not run
The speed control has thermally shut down. Allow the speed
control to cool down. Use a milder motor or a smaller pinion
gear. Check the drive train for restrictions. Check the motor
connections. Check the motors.
One motor is wired backwards. Check the wiring and correct.
Make sure the speed control is plugged into the throttle
channel of the receiver. Check operation of the throttle
channel with a servo.
Possible internal damage. Return the EVX to Traxxas
for service.
EVX will not go into programming mode
Make sure the EVX is plugged into channel 2 (the throttle
channel) on the receiver. If it is plugged into channel 3 or the
battery terminal, it will not go into programming mode.

Motor capacitors broken or missing - Check & replace
capacitors.
The receiver or antenna is too close to power wires or the
batteries.
Bad connections - Check the wiring and connectors.
Motor(s) worn - Replace the motors.
Excessive current to motor - Use a milder motor or a smaller

service.
Model runs slowly / slow acceleration
