PRECAUTION FOR USE

FEATURES

Before using this product, carefully read the important warnings
described in this instruction manual to understand the instructions thoroughly.

WARNINGDANGER

Instructions that the user must observe to prevent serious injury.

WARNING

Instructions that the user must observe to prevent accidents.

CAUTION

Useful information for handling this product.

About batteries
DANGER

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
DANGER

To prevent fumes, ﬁre, or burns

Incorrect wiring may cause ﬁre or fumes that can damage both the ESC andbattery beyond repair.

About special ceramic boardDANGERTo prevent burns

The surface of the special ceramic board will be extremely hot after heavy loaddriving. Do not touch the special ceramic board directly.

Handling precautions
WARNINGTo avoid accidents or product failure

Do not modify the ESC in any way. Use it only for its intended purpose. Keepthe ESC away from ﬂames or seat. Avoid splashing any liquid, such as water, onthe ESC.

2• Features ACUVANCEʼs original H.T.R.S* (patented), a hybrid design based on a special
thermal conductive carbon sheet and special heat-dissipating ceramic board thateﬃciently cools all FET components inside the ESC.
The only brushless ESC in the world that eliminates the need for heat sinks and coolingfans.
• 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 therange of available settings and ranges for a personal driving experience.
• Equipped with boost turbo, which expands the range of settings to match course
layouts.
• 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 toselect 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.

Be careful not to reverse the battery poles. Doing so can cause the ESC to fail.

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 theESC. 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), thelength of these cables can be changed and they can be easily replaced when they become damagedor broken.

WARNINGAC

Sensor cable
Capacitor

These cables apply voltage to the motor coil following a timing based on thesignals transmitted to the ESC via the sensor cable. The LUXON is pre-ﬁtted withcables terminated with bullet type connectors allowing connection to our ESC
TACHYON AIRIA without soldering.

WARNINGBe sure to match the cables to the symbols A, B, and C on the ESC. Failure tofollow this precaution can result in loss of control over the motor speed, orsubject 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 featurefor changing the rotating direction. The TACHYON AIRIA is equipped withthis feature (p.15)

WARNING

When replacing the motor cable, use a soldering iron with a broad tip and highoutput 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 (10seconds or more) can damage them. (Be careful not to short-circuit the terminalswith solder)
Use only screws 8 mm or shorter to mount the motor to the motor mount.

PREPARATIONS BEFORE DRIVING
When using this product for the ﬁrst time, the neutral position on your transmitter andthe ESC do not match. If you attempt to drive your car before completing theinitialization, 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 thatfollow in “Initializing the transmitter throttle position” when turning the power on forthe 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 originalstate. 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 thevehicle is being driven.
The three motor cables (A, B, C) may be left disconnected but be careful to nothave the cable connectors touch each other as they will short.
Preparations If performing the initial settings with the motor cables connected, secure themotor in a motor mount or other device, and remove the pinion gear to keep
the car from moving unexpectedly.

How to calibrate

Supports SANWA super response <SSR> mode

1 <<Before making calibration>>

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 ininitial setting mode. Release the set button.

Press and hold the set button
Green andorange LEDs

6While the green LED is blinking, set thethrottle on the transmitter to its neutral
position and press the set button on theESC once. The blue LED will start
blinking.

4 <<Setting the high point>>

While the blue LED is blinking, set thethrottle on the transmitter to themaximum 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 theset button with the throttle at the maximum
forward position, set the throttle to the
maximum reverse (brake) position and thenpress the set button once.

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 beconnected), and receiver. Then turn the transmitter power on.

3 <<Setting the neutral point>>

This completes the initial settings for thetransmitter positions. The ESC automaticallychanges 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 alltransmitter positions.

Caution The throttle position for the transmitter may become misaligned due tochanges or deterioration over time.
If the LED lights are ﬂashing while the ESC is in standby mode, readjust theinitial settings for the transmitter.
