Traxxas VXL-8s Instructions Manual

VXL-8s Electronic Speed Control Instructions

WARNING! CAUTION! DANGER!

Covers Part #3496

The VXL-8s electronic speed control requires use of Lithium Polymer (LiPo)
batteries with nominal voltage not to exceed 14.8 volts (4S packs). Charging
and discharging batteries has the potential for fire, explosion, serious injury,
and property damage if not performed per the instructions. In addition,
LiPo batteries pose a SEVERE risk of fire if not properly handled per the
instructions and require special care and handling procedures for long life
and safe operation. 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.
Dispose of used batteries according to the instructions.

• LiPo batteries have a minimum safe discharge voltage threshold that should
not be exceeded. The VXL-8s 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 is just one part of a comprehensive plan for safe LiPo
battery use. It is critical to follow all instructions for safe and proper charging,
use, and storage of LiPo batteries. Make sure you understand how to use
your LiPo batteries. If you have questions about LiPo battery usage, please
consult with your local hobby dealer or contact the battery manufacturer. As a
reminder, all batteries should be recycled at the end of their useful life.

•

A LiPo balance charger (such as the Traxxas EZ-Peak Live™, part #2971, sold
separately) is required to charge the batteries.
for NiMH or NiCad batteries. The use of a NiMH or NiCad charger or charge
mode will damage the batteries. Failure to use the correct charger may result in
battery damage, fire, personal injury, and/or property damage.

• ALWAYS inspect your LiPo batteries carefully before charging. Do not use
or charge battery packs that have been damaged in any way (bent, dented,
swollen, torn covering, or otherwise damaged).

• BEFORE you charge, ALWAYS confirm that the charger settings exactly match the
type (chemistry), specification, and configuration of the battery to be charged.
DO NOT exceed the maximum manufacturer recommended charge rate. DO NOT
attempt to charge non-rechargeable batteries (explosion hazard), batteries that
have an internal charge circuit or a protection circuit, or batteries that have been
altered from original manufacturer configuration.

FIRE HAZARD!

DO NOT use a charger designed

• While charging or discharging, ALWAYS place the battery
(all types of batteries) in a fire retardant/fire proof container
and on a non-flammable surface such as concrete.

• ALWAYS charge batteries in a well-ventilated area.

• Charge the battery in a safe area away from flammable materials. Monitor
the charging process and never leave batteries unattended while charging.
Do not allow small children to charge or handle LiPo batteries.

• DO NOT disassemble, crush, short circuit, or expose the batteries to flame or
other source of ignition.

• DO NOT let any exposed battery contacts or wires touch each other. This will
cause the battery to short circuit and create the risk of fire.

• DO NOT leave the charger and battery unattended while charging,
discharging, or anytime the charger is ON with a battery connected. If
there are any signs of a malfunction, unplug the power source and/or stop
the charging process immediately.

• ALWAYS unplug the charger from the wall outlet and disconnect the battery
when not in use.

• Never charge LiPo battery packs in series or parallel. Charging packs in series
or parallel may result in improper charger cell recognition and an improper
charging rate that may lead to overcharging, cell imbalance, cell damage
and fire.

• If a battery gets hot to the touch during the charging process (temperature
greater than 110°F / 43°C), immediately disconnect the battery from the
charger and discontinue charging.

• DO NOT store or charge LiPo batteries with or around other batteries or battery
packs of any type, including other LiPos.

• Store and transport your LiPo batteries in a cool dry place. DO NOT store in direct
sunlight. DO NOT allow the storage temperature to exceed 140°F or 60°C, such
as in the trunk of a car, or the cells may be damaged and risk of fire created.
ALWAYS store battery packs safely out of the reach of children and pets.

• Keep a Class D fire extinguisher nearby in case of fire.

• DO NOT disassemble LiPo batteries or cells. DO NOT disassemble the charger.

• DO NOT attempt to build your own LiPo battery pack from loose cells.

• REMOVE the battery from your model or device before charging.

• DO NOT expose the charger to water or moisture.

Important Precautions

VXL-8s Speed Control

• Disconnect the Battery: Always disconnect the battery or batteries from the

speed control when not in use. on the speed control to prevent runaways and
erratic performance.

• Insulate the Wires: Always insulate exposed wiring with heat shrink tubing to

prevent short circuits.

• Transmitter on First: Switch on your transmitter first before switching

• Don’t Get Burned: The ESC and motor can become extremely hot during use, so

be careful not to touch them until they cool. Supply adequate airflow for cooling.

• Use Traxxas High-Current Connectors: Do not change the battery and motor

connectors. Improper wiring can cause fire or damage to the ESC. Please note
that modified speed controls can be subject to a rewiring fee when returned
for service.

• No Reverse Voltage: The ESC is not protected against reverse polarity voltage.

• No Schottky Diodes: External Schottky diodes are not compatible with reversing

speed controls. Using a Schottky diode with your speed control will damage the
ESC and void the warranty.

• Always adhere to the minimum and maximum limitations of the speed control as

stated in the specifications. Your ESC operates on two batteries. Do not mix battery
types, capacities, or charge levels. Use the same voltage, capacity, and charge level
for both batteries. Using mismatched battery packs could damage the batteries
and electronic speed control.

Installation

The VXL-8s will install directly into most Traxxas models in the location of the
original speed control. The VXL-8s can also be installed in the chassis with double­sided servo tape (part #1589, sold separately). When mounting the speed control
with double-sided servo tape, clean both application surfaces thoroughly with
alcohol. The surfaces must be perfectly clean for maximum adhesion.

Here are some tips for choosing a location for the speed control:

• Monitoring temperatures will extend the lives of the batteries, motor, and
speed control. To ensure the speed control does not enter premature thermal
shutdown, install it in a well-ventilated location that will provide adequate
airflow during use. The VXL-8s is equipped with a cooling fan to assist in cooling

the speed control in high current motor applications.

• When mounting power components in a vehicle (wiring, motor, ESC), ensure that
none of the parts come into contact with any part of the radio system, particularly
the antenna wire. The receiver should be mounted so the antenna wire can be
extended as far away from the speed control as possible. The antenna wire should
be extended vertically in the mast and not wrapped on the chassis under the
body. Excess antenna wire should not be coiled on the chassis. Servo cables and
the antenna wire should not cross or come in contact with any of the motor or
battery wires. These steps will help reduce the possibility of radio interference.

• 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.

VXL-8s Wiring

The VXL-8s electronic speed control is capable of controlling sensorless brushless
motors. The VXL-8s auto-detects the motor type and has numerous built-in
safeguards to prevent damage from miswiring or damaged wiring.

Sensorless brushless motors

Sensorless motors are the easiest and most reliable brushless motor type.
The VXL-8s is optimized to deliver the smoothest possible sensorless motor
performance. The Velineon 1200XL is a sensorless brushless motor. The wiring
(phase alignment) of the motor determines its direction of rotation. Refer to the
wiring diagram below.

Transmitter Setup

Traxxas TQi Radio Systems

Before attempting to program your VXL-8s, it is important to make sure your TQi
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. 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).

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 VXL-8s is compatible with most aftermarket receivers.
By removing the tab on the edge of the power connector,
the VXL-8s can be plugged directly into some models of
Futaba®, Airtronics®, Hitec®, and JR® receivers. Please refer to the
manufacturer’s wiring diagrams that came with your receiver.

On the VXL-8s, 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 VXL-8s and an adapter is required.
Crossing the red (+) and black (-) wires could damage the receiver and the VXL-8s.
Study the manufacturer’s wiring diagrams closely, or consult your hobby dealer.

Low Voltage Detection

The VXL-8s electronic speed control is designed to operate on 4S, 6S, or 8S LiPo
battery power and is equipped with built-in two-stage Low Voltage Detection.
The Low Voltage Detection circuitry constantly monitors the battery voltage
and 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. When you turn your model on, the speed control’s status LED is green,
indicating that Low Voltage Detection is activated.

DO NOT use NiMH batteries with the
VXL-8s electronic speed control. The
batteries will become extremely hot
and damage or injury could occur.

VXL-8s Setup Programming

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, and start over.

1. Connect two fully charged battery packs to the VXL-8s.

2. Turn on the transmitter (with the throttle at neutral).

3. Press and hold the EZ-Set button (A). The LED will rst turn
green and then red. Release the EZ-Set button.

4. When the LED blinks RED ONCE, pull the
throttle trigger to the full throttle position
and hold it there (B).

5. When the LED blinks RED TWICE, push the throttle
trigger to the full reverse and hold it there (C).

6. When the LED blinks GREEN ONCE, programming is
complete. The LED will then shine green, indicating
the VXL-8s is on and at neutral.

VXL-8s Operation

To operate the speed control and test programming, place the vehicle on a stable
block or stand so that all of the drive wheels are off the ground. Disconnect motor
wires A and C, this will assure the motor does not drive the wheels during testing.
Do not test programming without disconnecting the motor wires. Note that in

steps 1-7 below, Low Voltage Detection is ACTIVATED (factory default) and the LED
shines green.

1. With the transmitter on, press and release the EZ-Set button. The LED will shine
green. This turns the VXL-8s on.

2. Apply forward throttle. The LED will turn o until full throttle power is reached.
At full throttle, the LED will illuminate green.

3. Move the trigger forward to apply the brakes. Note that braking control is fully
proportional. The LED will turn o until full braking power is reached. At full
brakes, the LED will illuminate green.

4. Return the throttle trigger to neutral. The LED will shine green.

5. Move the throttle trigger forward again to engage reverse (Prole #1). The LED
will turn o. Once full reverse power is reached, the LED will illuminate green.

6. Return the throttle trigger to neutral. (Note: There is programmed delay when
changing from reverse to forward. This prevents damage to the transmission on
high-traction surfaces.)

7. To turn the VXL-8s o, press the EZ-Set button until the LED turns o (0.5
seconds).

• Solid Green: VXL-8s power-on light. Low-Voltage Detection is

ACTIVATED (LiPo setting).

• Current LED (A) Solid Red: The VXL-8s has entered Overcurrent
Protection, Stage 1. When excessive current flow (amperage) is

being routed through the power system caused by failure to use
the appropriate gearing ratio for the drivetrain and the driving
surface, the VXL-8s will limit the power output to 50% throttle.
Make sure your model is properly geared for the driving conditions.
Before continuing, inspect the vehicle for damage. To reset, turn
the ESC off and back on again.

• Current LED (A) Fast Blinking Red: The VXL-8s has entered
Overcurrent Protection, Stage 2. When the current flow

(amperage) spikes temporarily due to a bound or restricted
driveline (model is stuck against an object or encountered a
restrictive driving surface), the VXL-8s will automatically shut down
(fail-safe mode). Stop driving the vehicle. The VXL-8s will stay in this
mode until the current flow is recovered (obstruction is removed,
model is moved to a smoother driving surface) and the throttle is
returned to neutral. To reset, turn the ESC off and back on again.

• Voltage LED (V) Solid Red: The VXL-8s has entered Low Voltage
Protection, Stage 1. When the battery voltage begins to reach

the minimum recommended discharge voltage threshold for

throttle. Stop driving the vehicle. The VXL-8s will stay in this mode
until the battery voltage is recovered or fully charged batteries are
connected.

• Voltage LED (V) Slow Blinking Red: The VXL-8s has entered Low
Voltage Protection, Stage 2. When the battery voltage attempts

to fall below the minimum threshold, the VXL-8s will automatically
shut down (fail-safe mode). The LED on the speed control will
slowly blink red, indicating a low-voltage shutdown. Stop driving
the model. The VXL-8s will stay in this mode until fully charged
batteries are connected.

• Voltage LED (V) Fast Blinking Red: If the motor has no power,
the VXL-8s has entered Overvoltage Protection. If the battery
voltage from the connected battery packs is too high, the VXL-8s
will go into a fail-safe mode. WARNING: If input voltage exceeds
approximately 33.6 volts (16.8 maximum peak input voltage per
battery pack), the ESC may be damaged. Do not exceed 33.6
maximum total peak voltage. Stop driving the model, turn the ESC
off, and disconnect the batteries.

• Temperature LED ( ) Solid Red: The VXL-8s has entered Thermal
Shutdown Protection, Stage 1 to guard against overheating

caused by excessive current flow. The VXL-8s will limit the power
output to 50% throttle. Stop driving the model. Inspect the cooling
fan on the ESC to make sure it is operating. Allow the power system
to cool before continuing.

• Temperature LED ( ) Fast Blinking Red: The VXL-8s has entered
Thermal Shutdown Protection, Stage 2 and has automatically

shut down (fail-safe mode). Stop driving the model. Inspect the
cooling fan on the ESC to make sure it is operating. Allow the
power system to cool before continuing. If you are experiencing
frequent warnings about temperature, it could be caused by
overgearing (from stock), overly aggressive and continuous high
speed driving, vehicle damage, or driving in conditions such as
deep sand, heavy mud, and tall grass.

• Current/Voltage/Temperature LEDs Solid Red or all LEDs Fast
Blinking Red: The VXL-8s has entered this protection mode

Traxxas High Current Connector

Your VXL-8s is equipped with the Traxxas High-Current Connector. Standard connectors

restrict current flow and are not capable of delivering the power needed to maximize the
output of the VXL-8s. The Traxxas connector’s gold-plated terminals with a large contact
surfaces ensure positive current flow with the least amount of resistance. Secure, long­lasting, and easy to grip, the Traxxas connector is engineered to extract all the power
your battery has to give.

To run this system, your batteries must be equipped with Traxxas High-Current

Connectors. Batteries must be purchased new with Traxxas connectors installed. For
best performance, your system requires LiPo battery packs that have cells rated for

Troubleshooting Guide

This guide describes possible speed control problems, causes, and simple solutions.
Check these items before contacting Traxxas.

Steering channel works but the motor 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 motor.

• Make sure the speed control is plugged into the throttle channel of the receiver.
Check operation of the throttle channel with a servo.

• Bad batter(ies) or motor. Check the operation with known good batter(ies) and
motor.

• VXL-8s: Possible internal damage. Return the VXL-8s to Traxxas for service.

Motor runs backwards:

• Motor wired backwards - Check the wiring and correct.

Motor runs as soon as the battery is plugged in:

• Internal damage; return VXL-8s to Traxxas for service.

VXL-8s will not go into programming mode:

• Make sure the VXL-8s is plugged into Channel 2 (the throttle channel) on the
receiver. If it is plugged into the battery terminal, it will not go into programming
mode.

• Be sure the VXL-8s is turned off before trying to program or select a profile.

• Unplug battery, reconnect, and repeat programming instructions.

• Check if transmitter is turned on.

high discharge and use high-quality, low-resistance assembly techniques. Cheaply
made battery packs do not retain their performance characteristics after repeated
uses in high-powered electric applications. They will lose their punch and run time
and may require frequent replacement. In addition, poor-quality, high-resistance
cell connectors could fail, requiring disassembly and repair. The main goal is to
reduce all sources of high resistance in the pack. This includes the connector, the
wire, and the bars attaching the cells together. High pack resistance will create
additional heat and rob you of the full power the cells are capable of producing.

Receiver glitches/throttle stutters during acceleration:

• The receiver or antenna is too close to power wires or the batteries.

• Bad connections. Check the wiring and connectors.

• Motor worn. Replace the motor.

• Excessive current to motor (over-geared motor). Use a smaller pinion gear.

• Battery voltage low. Recharge and/or verify charged status.

• Disconnected brushless motor lead. Reconnect according to appropriate wiring
diagram.

Model runs slowly / slow acceleration:

• Check the motor and battery connectors.

• Check to see if the VXL-8s is in Profile #3 (50% throttle).

• Bad batter(ies) or motor. Check the operation with known good batter(ies) and
motor.

• Incorrect transmitter or speed control adjustment. Refer to the Transmitter Setup
and VXL-8s Setup Programming sections.

• VXL-8s is in Thermal Shutdown Protection. Allow to cool and check for proper
gearing.

• VXL-8s has entered Low-Voltage Protection.

Model will not go in reverse:

• Make sure the throttle trim is in the correct position (LED on VXL-8s should be lit
solid at neutral throttle).

• Check for correct VXL-8s profile (Profile #2 does not have reverse).
