Useful information for handling this product.
About batteries
To prevent fumes, fire, or burns
Improper use of the battery is very dangerous. The battery must be handled carefully.
Incorrect wiring or short-circuiting of wiring may cause fire or fumes. Before
connecting or disconnecting the battery to or from the speed controller (ESC), be
sure to turn off the power switch of the ESC. When the battery is not in use,
disconnect it from the ESC or charger, and store it in a suitable location free of any
loose wires or screws.
About cable Connections
To prevent fumes, fire, or burns
Incorrect wiring may cause fire or fumes that can damage both the ESC and
battery beyond repair.
About special ceramic board
To prevent burns
The surface of the special ceramic board will be extremely hot after heavy load
driving. Do not touch the special ceramic board directly.
Handling precautions
To avoid accidents or product failure
Do not modify the ESC in any way. Use it only for its intended purpose. Keep
the ESC away from flames or seat. Avoid splashing any liquid, such as water, on
the ESC.
• Features ACUVANCE s original H.T.R.S* (patented), a hybrid design based on a special
thermal conductive carbon sheet and special heat-dissipating ceramic board that
efficiently cools all FET components inside the ESC.
The only brushless ESC in the world that eliminates the need for heat sinks and cooling
• The small body has been laid out with 24 of the latest power MOS-FET components.
This optimizes the circuitry to achieve high efficiency while supporting reverse braking.
• Push button controls on the ESC allow you to disengage reverse braking and change
drive frequency, brake volume, and other settings.
Users can add a dedicated effector (sold separately) that significantly expands the
range of available settings and ranges for a personal driving experience.
• Equipped with boost turbo, which expands the range of settings to match course
• The settings support visual confirmation of non-boost zero timing via LED as well as
non-boost regulation.
• The sensor cable , receiver cable , and switch cable are detachable.
This makes it possible to easily replace cables when they break and allows you to
select the length of the cable to match the layout (when using optional parts).
• Supports SSR mode , a Sanwa Denshi Co. Ltd. original system.
*H.T.R.S.: Hybrid Thermal Radiation System (patented)
World's first Hybrid Thermal Radiation System* cools all FET components
evenly and more efficiently than a cooling fan and heat sink.

LUXON Series brushless motor
Orange tube
Yellow tube
This cable transmits position signals to the ESC using a Hall element. The connector has the same
shape on both the ESC side and the motor side, allowing it to be plugged in either direction. It should
however be connected to the proper shape. This cable must be connected in order to initialize the
ESC. Be sure the connector fits snugly to prevent loose connections which can cause malfunctioning
and product damage. Never modify the uncap sensor cable. Doing so may cause product failures.

Switch cable/receiver cable
The switch cable and receiver cable are detachable. By using optional parts (sold separately), the
length of these cables can be changed and they can be easily replaced when they become damaged
or broken.
Blue tube
Sensor cable
These cables apply voltage to the motor coil following a timing based on the
signals transmitted to the ESC via the sensor cable. The LUXON is pre-fitted with
cables terminated with bullet type connectors allowing connection to our ESC
TACHYON AIRIA without soldering.
Be sure to match the cables to the symbols A, B, and C on the ESC. Failure to
follow this precaution can result in loss of control over the motor speed, or
subject the ESC and motor to large currents. Unlike brushless motors without
a sensor, swapping these cables does not change the rotating direction of
the motor. If necessary, change the direction of rotation at the ESC*.
* To change the rotating direction, the ESC must be equipped with a feature
for changing the rotating direction. The TACHYON AIRIA is equipped with
this feature (p.15)
When replacing the motor cable, use a soldering iron with a broad tip and high
output rating (as high as 60 W) and work swiftly. A soldering on with the low
output rating will not melt enough of the solder resulting in a poor soldering
connection which can cause cables to loosen under vibration or loose connections.
Also, subjecting the internal parts to excessive heat over prolonged periods (10
seconds or more) can damage them. (Be careful not to short-circuit the terminals
with solder)
Use only screws 8 mm or shorter to mount the motor to the motor mount.

If the sensor cable is not connected, has not been properly inserted, has been
disconnected, or is loosely connected, all the LEDs will blink (high-speed blinking).
While in this state, all operations will not be received. If this occurs, check
the connection for the sensor cable or replace the cable.
KEYENCE offers sensor cables, receive cables, and switch cables of various
lengths as optional parts (sold separately).
When using this product for the first time, the neutral position on your transmitter and
the ESC do not match. If you attempt to drive your car before completing the
initialization, the motor may start rotating as soon as the switch is turned on.
This is extremely dangerous and can be prevented by performing the procedures that
follow in Initializing the transmitter throttle position when turning the power on for
the first time. (The motor will not rotate during the initialization).
Initializing the transmitter throttle position
The ESC must be programmed with the transmitter's neutral position, forward
MAX position, and reverse (brake) MAX position immediately after purchase, or if
the transmitter has been replaced. Perform the following steps.
Preparations Before performing this setting, set all transmitter throttle settings
(EPA= end point adjustments, MAX brake volume, etc.) to their original
state. Otherwise, the ESC will not detect the transmitter signals properly,
preventing it from being initialized.
When performing the initial setting, be sure that the sensor cable is connected to the motor and ESC.
Preparations If the sensor cable is not connected, has not been properly inserted, has been
disconnected, or is loosely connected, all the LEDs will blink (high-speed blinking).
Check the connection for the sensor cable or replace the cable as all operations
will not be received while it is in this state. Also, in addition to when performing
the initial settings, the sensor cable should always be connected when the
vehicle is being driven.
The three motor cables (A, B, C) may be left disconnected but be careful to not
have the cable connectors touch each other as they will short.
Preparations If performing the initial settings with the motor cables connected, secure the
motor in a motor mount or other device, and remove the pinion gear to keep
the car from moving unexpectedly.

<<Setting the neutral point>>
While the green LED is blinking, set the
throttle on the transmitter to its neutral
position and press the set button on the
ESC once. The blue LED will start

<<Setting the high point>>
While the blue LED is blinking, set the
throttle on the transmitter to the
maximum forward position and press
the set button on the ESC once. The red
LED will start blinking.
* If the red LED does not blink after pressing the
set button with the throttle at the maximum
forward position, set the throttle to the
maximum reverse (brake) position and then
press the set button once.
<<Setting the brake high point>>
While the red LED is blinking, set the

<<Before making calibration>>
Be sure the ESC power is turned off, and make sure the ESC is properly
connected to the battery, motor (only the Sensor cable needs to be
connected), and receiver. Then turn the transmitter power on.
<<Calibration mode>>
Press and hold down the set button while turning
the ESC power on. The green and orange LEDs will
blink for three seconds, and then the green LED
will start blinking indicating that the ESC is in
initial setting mode. Release the set button.
Press and hold the set button

*At this time, it will be automatically determined if the receiver possesses SSR mode.
This completes the initial settings for the
transmitter positions. The ESC automatically
changes to the standby mode (p. 8).
All LEDs blink

IMPORTANT If you performed the procedure described by the * under Step 4 above,
<<Setting the high point>>, switch the throttle channel on the transmitter
between normal and reverse after completing the initial setting for all
transmitter positions.
Caution The throttle position for the transmitter may become misaligned due to
changes or deterioration over time.
If the LED lights are flashing while the ESC is in standby mode, readjust the
initial settings for the transmitter.
