Battery cables

A

This cord 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 beconnected to the proper shape. This cord must be connected in order toinitialize the ESC. (Leave this cord connected while driving). Be sure theconnector fits snugly to prevent loose connections which can cause
malfunctioning and product damage. Never modify the uncap sensor cord.
Doing so may cause product failures.
These cables apply voltage to the motor coil following a timing based on thesignals transmitted to the ESC via the sensor cord. The LUXON is pre-fittedwith cables terminated with bullet type connectors allowing connection to
our ESC TACHYON without soldering.
CAUTION

When soldering cables, use soldering iron with a high wattage rating (ashigh as 60 W) and complete the work in a short period of time. Prolonged
soldering times using a low wattage soldering iron can damage theelectrical components inside the ESC.

PREPARATIONS BEFORE DRIVING
When using this product for the first time, the neutral position on your transmitterand the 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 following this procedurewhen turning the power on for the first time, "Initializing the transmitter throttle
position". (The motor will not rotate during the initialization).

PREPARATIONS BEFORE DRIVING
Verifying the transmitter positions have been correctly set to their initial settings
The main LED (see below) should be the only one illuminated when the throttle isin the neutral, maximum forward, and maximum reverse (brake) positions. If themain LED is unlit in all other positions, the initial setup has been completed
properly.
(At time of shipment, the main LED is the only LED that alternately illuminates andgoes out when adjusting the throttle.)

IMPORTANT While driving, if the battery voltage drops to the cutoff voltage level, themotor will gradually stop rotating and the yellow LED will blink indicating
you should replace the battery.

(3) Sub LED (orange): Factory shipped condition = lit
Illuminated when the reverse drive feature (p.14) is set to ON. Unlit when set toOFF.

(4) Main LED (red): Factory shipped condition = unlit
Main LED when setting mode (p. 10) is in Program Card mode. Unlit during ESC
mode.
IMPORTANT If the ESC heats to a hazardous temperature while driving, the motor will

gradually stop rotating and the red LED will blink. If this situation occurs,
discontinue operation and let the ESC stand at room temperature. If the red
LED starts blinking after driving for only a brief period, check to see if thegear ratio is overloading the motor.

If the main LED does not follow this lighting pattern, the initial setting was notcompleted properly. Make sure the throttle related adjustments on the transmitterare initialized and the RX cable is properly connected to the receiver. Then, retry
the initial setting procedure.
* In some cases, the drive circuit may cause the car to move in reverse when the throttle isoperated in the forward direction. If your car displays this behavior, change the rotating
direction of the motor (P. 15).

[Important] Safety feature for driving in reverse
On radio-controlled cars, the same throttle controls are used for braking anddriving in reverse. This can cause the car to move backwards when the intention is
to apply the brakes. Suddenly trying to reverse the motor while it is rotating
forward can place severe stress on the gears, motor, and ESC, sometimes resulting
in internal damage. The TACHYON is equipped with the following feature toprevent this.
After applying the brakes, a vehicle starts to back up by the throttle being turnedto the brake side one or more seconds after the throttle is returned to neutral
once. Also, the motor, which is rotating in the forward direction, comes to acompete stop. (A vehicle does not back up unless one or more seconds pass.)
In this way, even if the reverse drive feature is set to ON, the ESC ensures that any
throttle operation in the braking direction results in braking and no unintentional
reversing. This feature prevents damage to the drive parts and collisions with othercars, as well as many other possible problems, and is essential to allow short
braking action when turning corners.
* Note, this safety feature cannot be disabled.

Main mode at time of shipment(1) Main LED (blue): Factory shipped condition = lit
Main LED when setting mode (p. 10) is in ESC mode. Unlit during Program Card
mode.

This completes the preparation before driving. Connect the motor and enjoy
driving.
* When using lithium polymer batteries, set the cutoff voltage before driving to Li-Po 2-cellor Li-Po 3-cell (p. 14).

(2) Sub LED (yellow): Factory shipped condition = unlit
At time of shipment, the battery setting is Ni-cd/Ni-MH/Li-Fe and the LED is
unlit. This LED is illuminated when the cutoff voltage (p. 14) is set to Li-Po2 cell,or Li-Po3 cell. (Set the cutoff voltage when using a Li-Po battery.)
