TRAXXAS
The electronic speed control is factory set and should not require any
adjustments. These instructions are provided for your reference.
Transmitter Adjustments for the electronic speed control
Before attempting to program your ESC, it is important to make
sure your TQ transmitter is properly adjusted (set back to the factory
defaults). Otherwise, you may not get the best performance from your
speed control.
The transmitter should be adjusted as follows:
1. Set the throttle neutral switch to the 50/50 setting. This adjusts
the transmitter’s throttle trigger throw to 50% for throttle and
50% for braking and reverse.
2. Set the throttle trim control to the middle “0” setting.
3. Set the Channel 2 servo reversing switch to the left position. Do
not change the position of any of the servo reversing switches
after programming the ESC.
4. You are now ready to program your speed control.
Setup Programming (Calibrating your ESC and transmitter)
Read through all of the following programming steps before you
begin. If you get lost during programming or receive unexpected
results, simply unplug the battery, wait a few seconds, plug the battery
back in, and start over.
1. Disconnect each of the motor wires between the ESC and the
motor. This is a precaution to prevent runaway when the speed
control is turned on before it is programmed.
2. Connect a fully charged battery pack to the ESC.
3. Turn on the transmitter (with the throttle
at neutral).
4. Press and hold the EZ-Set button (A). The LED
will rst turn green and then red. Release the
EZ-Set button.
5. When the LED blinks RED ONCE.
Pull the throttle trigger to the
full throttle position and hold it
there (B).
6. When the LED blinks RED TWICE.
Push the throttle trigger to the
full reverse and hold it there (C).
7. When the LED turns solid GREEN, programming is
complete. The LED will continuously shine green
indicating the ESC is on and at neutral (D).
ESC Operation
To operate the speed control and test the programming, place the
vehicle on a stable block or stand so all of the driven wheels are off the
ground. Reconnect the motor wires. Always make sure that objects and
ngers are clear of the wheels.
1. With the transmitter on, press the EZ-Set button for ½ second,
until the LED shines GREEN, then immediately release the button.
This turns on the ESC. If you press and release too quickly, you
may hear the steering servos jump but the LED may not stay
on. (Note: If the throttle is not at neutral or if the throttle trim
has been altered, the LED will turn off after one second and the
wheels may begin to drive.)
2. Apply forward throttle. The LED will turn off until full throttle
power is reached. At full throttle, the led will shine GREEN.
3. Move the trigger forward to apply the brakes. Note that braking
control is fully proportional. The LED will turn off until full braking
power is reached. At full brakes, the LED will shine GREEN.
4. Return the throttle trigger to neutral. The LED will shine GREEN.
5. Move the throttle trigger forward again to engage reverse
(Prole #1). The LED will turn off. Once full reverse power is
reached, the LED will shine GREEN.
6. To stop, return the throttle trigger to neutral.
(Note: There is no programmed delay when changing from
reverse to forward. Use caution to avoid slamming the speed
control from reverse to forward. On high-traction surfaces, this
could result in transmission or driveline damage.
7. To turn the ESC off, press the EZ-Set button until the green LED
turns off.
Thermal Shutdown Protection
The XL-2.5 speed control is equipped with thermal shutdown protection
to guard against overheating caused by excessive current ow. If the
operating temperature exceeds safe limits, the ESC will automatically
shut down and the ESC LED will ash red. The LED on the face of the
ESC will continuously ash red, even if the throttle trigger is moved back
and forth. After the speed control cools down to a safe level, the LED will
continuously shine green. The ESC will once again function normally.
