Thank you for purchasing the Traxxas MXL-6s
™
electronic speed control.
The MXL-6s forward/reverse/brake electronic speed control simplifies
brushless technology with easy and intuitive programming. The MXL-6s
uses advanced circuit design that allows sensorless brushless motors to
operate with the smoothness and precision of the best brushed systems.
The MXL-6s comes with the peace-of-mind of the Traxxas Lifetime
Electronics Warranty and unmatched Traxxas customer support. The MXL-6s
is not a toy. It is a sophisticated electronic device capable of delivering large
amounts of current. Children under 14 years of age require adult supervision
for use of the MXL-6s. If you have questions or need assistance call us at
1-888-TRAXXAS*.
Important Precautions
MXL-6s Speed Control
• Water and Electronics Do Not Mix: Your MXL-6s brushless power system
is waterproof for use in mud, snow, puddles and other wet conditions.
Make certain the other components of your model are waterproof or have
sufficient water resistance before driving in wet conditions.
• Disconnect the Batteries: Always disconnect the battery pack 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 the same-gender connectors 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
Batteries and Battery Charging
The MXL-6s Power System
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.
• Allow the battery packs to cool off between runs (before charging).
• Always unplug the battery from the electronic speed control when the
model is not in use and when it is being stored or transported.
• 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.
LiPo Batteries
Lithium Polymer (LiPo) batteries are becoming popular for use in R/C
models due to their compact size, high energy density, and high-current
output. However, these types of batteries require special care and handling
procedures for long life and safe operation. WARNING: LiPo batteries are
intended only for advanced users that are educated on the risks associated
with LiPo battery use. Traxxas does not recommend that anyone under
the age of 14 use or handle LiPo battery packs without the supervision of
a knowledgeable and responsible adult.
The MXL-6s electronic speed control is able to use LiPo batteries with nominal
voltage not to exceed 11.1 volts (3S packs) for each battery (6S total). LiPo
batteries have a minimum safe discharge voltage threshold that should
not be exceeded. The MXL-6s electronic speed control is equipped with
built-in Low-Voltage Detection that alerts the driver when LiPo batteries
have reached their minimum voltage (discharge) threshold. It is the driver’s
responsibility to stop immediately to prevent the battery pack from
being discharged below its safe minimum threshold.
Low-Voltage Detection on the speed control is just one part of a
comprehensive plan for safe LiPo battery use. It is critical for you, the user,
to follow all other instructions supplied by the battery manufacturer
and the charger manufacturer for proper charging, use, and storage of
LiPo batteries. Make sure you understand how to use your LiPo batteries.
Be aware that Traxxas shall not be liable for any special, indirect, incidental,
or consequential damages arising out of the installation and/or use of LiPo
batteries in Traxxas products.
If you have questions about LiPo battery usage, please consult with your
local hobby dealer or contact the battery manufacturer.
Installation
Attach the MXL-6s speed control to the chassis in the original speed control
location using the included double-sided servo tape and mounting bracket.
