Installation
Here are some tips for choosing a location for the speed control:
• The XL-5 does not use a conventional on/off switch. Pressing the EZ-Set
button on the speed control turns it on and off. It is not necessary to
install an on/off switch into the wiring harness.
• Mount the speed control where it will be protected from crash damage.
Also, protect the speed control from dirt and debris kicked up by the tires.
• Mount the speed control where you will have easy access to the plugs
and the on/off (EZ-Set) button without having to remove the body.
• Mount the speed control so that none of the power components
(wiring, motor, ESC) contacts any part of the radio system, particularly
the antenna wire.
• Graphite or metal chassis have been known to transmit radio noise
generated by the motor. If the receiver is to be mounted on the chassis,
position it so the antenna is as far away from the chassis as possible.
This may require you to mount the receiver on its side. This will reduce
the chance of picking up radio interference from the motor.
• When mounting the speed control with double-sided servo tape, clean
both application surfaces thoroughly with alcohol to remove any
grease, dirt, oil, fingerprints, etc. The surfaces must be perfectly clean
for maximum adhesion.
• The motor requires capacitors to reduce the possibility of radio
interference. If your motor is not equipped with capacitors, install the
capacitors supplied with the XL-5 as shown in the diagram below.

Transmitter Setup
Traxxas TQ Radio Systems
Before attempting to program your XL-5, 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. Experienced users may wish to use the 70/30
setting if more broad proportional control is desired in forward
than with braking and reverse. This might be desirable in a racing
environment where reverse is disabled.
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 XL-5.
4. You are now ready to program your speed control.
Aftermarket (Non-Traxxas) Transmitters
The following instructions are provided as a general reference
only for those who are using non-Traxxas transmitters. Consult your
transmitter's instructions for information on how to change the settings.
1. Set the High ATV (adjustable travel volume) or EPA (end point
adjustment to the maximum setting. This is the amount of servo throw
at full throttle.
2. Set the Low ATV, EPA or ATL (low side only trim adjustment) to the
maximum setting. This is the amount of servo throw at full brakes or reverse.
3. Set the throttle trim to the middle (neutral setting).

Motor
4. Set the throttle channel reversing switch to either position. Do not
change the switch position after programming.
5. Set the trigger throw adjustment to 50% throttle and 50% brake
(either mechanical or electronic).
6. Set the exponential setting (if equipped) to the zero or fully linear setting.
Aftermarket Receivers
The XL-5 is compatible with most aftermarket
receivers. By removing the tab on the edge of
the power connector, the XL-5 can be plugged
directly into some models of Futaba
Hitec , and JR receivers. Please refer to the
® ®
manufacturer's wiring diagrams that came with
your receiver. On the XL-5, the red wire is positive, the black wire is
negative, and the white wire is the control wire. WARNING: On some
older Airtronics® radio systems, the positive and negative terminals are
opposite of the XL-5 and an adapter is required. Crossing the red (+)
and black (-) wires could damage the receiver and the XL-5. Study the
manufacturer's wiring diagrams closely, or consult your hobby dealer.
Low-Voltage Detection Settings
The XL-5 speed control includes Low-Voltage Detection circuitry for
use with LiPo batteries. This feature can be disabled for use with NiMH
batteries. The Low-Voltage Detection circuitry constantly monitors the
battery voltage. When the battery voltage begins to reach the minimum
recommended discharge voltage threshold for LiPo battery packs, the
XL-5 will limit the power output to 50% throttle. When the battery
voltage attempts to fall below the minimum threshold, the XL-5 will shut
down all motor output. The LED on the speed control will slowly blink
red, indicating a low-voltage shutdown. The XL-5 will stay in this mode
until a fully charged battery is connected.
Be certain Low-Voltage Detection is enabled if you install LiPo batteries
in your model. Never use LiPo batteries while Low-Voltage Detection
is disabled.
Verify that Low-Voltage Detection is DISABLED:
1. Turn on the transmitter (with the
throttle at neutral).
2. Connect a fully charged battery
pack to the XL-5.
3. Press and release the EZ-Set button
to turn the XL-5 on. If the LED is solid RED, then the Low-Voltage
Detection is DISABLED (not safe to use LiPo batteries). If the LED is
solid GREEN, then Low-Voltage Detection is ACTIVATED.
To activate Low-Voltage Detection (LiPo setting):
1. Make sure the LED on the XL-5
is on and RED.
2. Press and hold the EZ-Set button
(the LED will turn off) (A). After ten
seconds, the motor will beep twice
and the LED will shine GREEN. Release the button (B).
3. Low-Voltage Detection is now ACTIVATED.
To disable Low-Voltage Detection (NiMH setting):
1. Make sure the LED on the XL-5 is
on and GREEN.
2. Press and hold the EZ-Set button
(the LED will turn off) (A). After ten
seconds, the motor will beep three
times and the LED will shine RED. Release the button (B).
3. Low-Voltage Detection is now DISABLED.

Setup Programming
The XL-5 must be programmed to work with the transmitter. The XL-5
has to learn where the neutral, full throttle, and full brake (reverse) points
are located on the throttle trigger. Programming is accomplished by
pressing the EZ-Set button on the ESC in sequence with the signals from
®
the flashing LED. Read through all of the 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,
