The following instructions will help you get trouble-free operation from your
electronic speed control (ESC). These simple steps will allow your ESC to
achieve maximum performance and minimize the chance of problems due to
incorrect installation. Consult the specifications listed below for limitations on
this ESC. You should always ask your hobby dealer or call our service
department before using the ESC for an application other than what is listed
in these instructions.
PLEASE FOLLOW ALL INSTRUCTIONS CAREFULLY!

• Sets up automatically from the transmitter (Tx) for convenience.
• High frequency operation provides very smooth control, maximizes battery
run time, and reduces operating temperatures.
• Motor, battery, and radio connectors arrive pre-installed.
• High frequency operation provides very smooth control, maximizes battery
run time, and reduces operating temperatures.
• High temperature control automatically shuts down the ESC to prevent
damage from occurring during excessive current situations.

FEATURES & SPECIFICATIONS
STEP 1:
MOUNTING THE ESC & RECEIVER
The following information can help the ESC perform at maximum efficiency
and minimize the chance of overheating and radio interference problems.
MOUNTING THE ESC (Figure 1)
1. Locate the ESC in a position to allow for good airflow, with as little obstruction
from the model’s outer body or exterior dirt and debris as possible. Maintaining a
clean ESC and achieving good airflow
through
the heat sink fins is very important
for keeping the ESC cool and maximizing performance.
2. Mount the ESC using double-sided mounting tape.
3. Mount the ON/OFF switch in a convenient place. Ensure that it is securely
mounted, using mounting tape or screws in a location where it cannot be
easily turned off by objects on the track or rough terrain.
MOUNTING THE RECEIVER
1. Radio interference can cause the ESC to rapidly switch between forward and
brake, overheating the transistors and possibly damaging the ESC. The Rx
and its antenna should be mounted as far away from the ESC as possible.
Also, try to keep the Rx away from the motor, battery, power wires, servos,
or any large piece of metal – such as a metal chassis.
2. Make sure the Rx antenna can be fully extended through a mast and not
completely enclosed inside the model. Do NOT cut or coil the Rx antenna.
3. Mounting the Rx deep within the tub of the chassis can greatly increase the
chance for radio interference. Try to mount the Rx away from the bottom of
the chassis tub.
4. Graphite and metal chassis’ transmit radio noise generated by the motor. To
mount the Rx on a graphite chassis (if necessary), place it on edge with the
crystal and antenna as far away from the chassis as possible to reduce the
chance of radio interference.

cars, or cars with a

chassis, mount the

interference.
STEP 2:
MOTOR & CAPACITOR CONNECTIONS
Motors generate electrical noise which can interfere with radio reception.
Properly installed capacitors can help reduce the chance of such interference.
Some motors come from the factory with capacitors pre-installed. Check the
motor’s instructions to see if capacitors are in place. Otherwise, installation of
the three included 0.1µF 50V non-polarized ceramic capacitors onto the motor
is highly recommended.
• Solder one capacitor between the motor’s POSITIVE (+) brush tab and
GROUND tab†.
• Solder one capacitor between the motor’s NEGATIVE (-) brush tab and
GROUND tab†.
• Solder one capacitor between the motor’s POSITIVE (+) and NEGATIVE (-) tabs.
† Solder to the can of the motor if your motor doesn’t have a ground tab.

STEP 3:
TRANSMITTER ADJUSTMENTS
Adjusting your Tx is critical for proper ESC operation. The 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.
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.
STEP 4:
RADIO CONNECTOR POLARITIES
Clip tab
• Do not run the car near water! Never allow water, moisture, or any foreign
material inside the case of the ESC.
• Never use more than 7 cells (8.4 volts total) in the main battery pack.
• Do not attempt to connect the battery pack to the ESC in reverse, as
permanent damage could result.
• 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 wires. Do not connect a battery to the
receiver’s (Rx) “battery” slot. The Rx receives power through the ESC itself,
which plugs into the Rx’s throttle channel slot.
• Three 0.1µF, 50V monolithic capacitors (included) should be properly
installed on any motor that does not have built-in capacitors to reduce
interference from electronic noise. (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 Rx and switching on the Tx.
• Be careful not to touch the heat sink during use as it can become very hot.
• For the best performance, use an FM radio system.
