HOOK-UP INSTRUCTIONS
Motors generate radio noise, which can interfere with your receiver and
cause problems. Check your motor to see if it has capacitors installed
on it. Some motors have capacitors built in so refer to the motor's
instructions. If the motor does not have capacitors installed, you might
need to install two (not included) 0.1µF, 50V, non-polarized, ceramic
capacitors onto the motor. These capacitors will help reduce radio noise
generated by the motor and prevent possible damage to the speed
control. Solder the capacitors between:
• POSITIVE (+) motor brush tab & GROUND motor tab†.
• NEGATIVE (-) motor brush tab & GROUND motor tab†.
Adjusting your transmitter is critical for proper speed control operation.
The transmitter (TX) throttle adjustments are described below:
• ATV, EPA, or ATL - set all to maximum.
• Throttle Trims and Sub Trims - set all at neutral or zero.

ELECTRONIC SPEED CONTROL
OPERATING INSTRUCTIONS
The following instructions will help you get trouble-free speed control
operation. These simple steps will allow your speed control to achieve
maximum performance and minimize the chance of problems due to
incorrect installation.
Consult the specifications printed in the table below for limitations on
the number of cells that the speed control can be used with. You should
always ask your hobby dealer or call our service department before
using the speed control for an application other than what is listed in
these instructions.
The Sprint has a reverse polarity protection circuit, which protects the
speed control if the battery pack is hooked-up backwards. To reset the
ESC turn it off and then back on, there is not a delay.
The Sprint is designed to be used with any 20-27 turn stock motor and
run on 6 to 7 cells only (1.2 volts/cell connected in series). Using more
than 7 cells may damage the speed control and void the warranty.
STEP 1
MOUNTING THE SPEED CONTROL
IMPORTANT INSTRUCTIONS
(ESC=ELECTRONIC SPEED CONTROL)
The following mounting information will assure that your speed control
performs at maximum efficiency and minimizes the chances of
overheating and radio interference problems.
Mounting the Speed Control (Figure 1)
1. Mount the ESC to the chassis using mounting tape. Mounting the
ESC to achieve good airflow through the heat sinks is very important
for maximum performance. The ESC should be mounted as far away
from the receiver as possible to prevent radio interference.
2. Mount the ON/OFF switch in a convenient place using mounting
tape or screws.
Mounting the Receiver
1. To prevent radio interference, mount the receiver and antenna at
least two inches away from the motor, batteries, power wires, servo,
or any large piece of metal - such as a metal chassis.
2. Mounting the receiver in the tub of the chassis greatly reduces the
range of your radio and increases the chance of radio interference.
3. If your car has a graphite chassis, and you want to mount the
receiver on the chassis, mounting the receiver on edge with the
crystal and antenna as far away from the chassis as possible
reduces the chance of radio interference.
• Do not run the car near water! Never allow water, moisture, or any
foreign material onto the ESC's PC board.
• Never use more than 7 cells (8.4 volts total) in the main battery pack.
• Do not mix instructions. If you are building a vehicle that has a
mechanical speed control, do not use the wiring diagram included
with the vehicle.
• Never cut or splice the ESC input harness wires. The receiver does
not need to have anything plugged into the "battery" slot. It receives
power through the ESC input harness which plugs into the
CHANNEL 2 slot.
• Two 0.1µF (50V) monolithic capacitors (not included) should be
properly installed on any motor that does not have capacitors built in.
(See step 2)
• Always disconnect the battery pack from the ESC when not in use.
• Never turn on the ESC before plugging it into the receiver and
switching on the transmitter.
• Be careful not to touch the heat sink when it is hot.
PLEASE FOLLOW ALL INSTRUCTIONS CAREFULLY!

By simply clipping off the tab on the side of the connector using wire
cutters, it can be directly connected to any Futaba® J, Airtronics "Z",
Hitec "S", or JR receiver. For proper connection refer to your radio's
manual. WARNING: This connector is NOT directly compatible with the
old Airtronics connector style. For old Airtronics radios, it is highly
recommended to use an Airtronics Servo Adapter to connect this ESC
to the older style Airtronics radios. NEVER ALLOW THE RED (+) AND
BLACK (-) WIRES TO CROSS ON ANY RECEIVER OR ESC AS
PERMANENT DAMAGE WILL RESULT TO BOTH ITEMS.

TROUBLE SHOOTING GUIDE

Before you begin this step, your speed control should be plugged into
the receiver and your transmitter should have already been adjusted.
Before you connect the main battery pack to the speed control, make
sure that the ESC switch is turned off. Connect the battery pack to the
speed control and turn on the transmitter. Make sure the throttle
trigger is in the Neutral position before turning on the ESC.
1) With the transmitter throttle trigger in neutral, turn on the ESC. The
green LED will light up for about 1 second.
2) Pull the throttle trigger to full forward, the red LED will light up to
indicate the full forward is now being operated.
3) Push the throttle trigger to full reverse, the green and red LED will
light up to indicate full reverse is now being operated.
4) The ESC will hold this setting until it is reset.
5) Repeat this procedure if any or all steps fail to operate as expected.
(Note: The motor does not function during the set-up process.)
Note: If the throttle is set to full forward on the transmitter and you get
reverse operation instead of forward operation, the throttle-reversing
switch on the transmitter must be switched.
STEP 5
SPEED CONTROL SET-UP
Radio interference can cause the speed control to rapidly switch
between forward and full brakes, causing overheating of the brake
transistors and possible damage to the ESC. Here are a few of the most
common causes of radio problems:
•Capacitors not installed on motor. Electric motors generate radio
noise that can interfere with the receiver. To prevent radio problems,
every motor should have two 0.1µF (50V) ceramic capacitors installed
(See step 2).
•Receiver mounted on graphite or metal chassis. Graphite and
metal chassis transmit radio noise generated by the motor. To prevent
radio problems, mount the receiver on the rear shock tower or away
from the chassis. If the receiver is mounted on the chassis, stand it
on its side with the crystal as far away from the chassis as possible.
•Receiver antenna cut or coiled wrong. If the receiver's antenna is
cut, the range will be reduced. The antenna should be mounted away
from the motor and power wires. Coiling the antenna wire, or keeping
the entire antenna inside the body will reduce the range and increase
the risk of radio problems.
PREVENTING RADIO PROBLEMS
PLEASE NOTE: Speed controls that operate normally when received
will be charged a minimum service fee and return shipping charges.
Before sending your speed control in for service, it is important that
you review the Trouble-Shooting Guide in this instruction set. The
speed control may appear to have failed when other problems exist in
the system such as a defective transmitter, receiver or servo, or
incorrect adjustments/installation.
•Hobby dealers are not authorized to replace speed controls thought
to be defective.
•Do not cut the input harness, switch harness, or power wires of the
speed control before sending it for service. A fee will be charged for
cut wires which must be replaced for testing.
