Declarations and Warnings
FS-GT15 Rx is a highly-integrated multifunction ESC. It has built-in functions of
ESC, servo and 2-channel receiver. It must work with right motor and servo in order
to get FS-GT15 Rx work properly, otherwise the FS-GT15 RX will be destroyed.
Don’t block the motor for a long time, which will damage the ESC.
Don’t block the servo for a long time, which will damage the servo driver.

Transmitter
WARNING: BATTERIES ARE SUITABLE FOR 4 ALKALINE BATTERIES.
ENSURE THAT THE POSITIVE AND NEGATIVE POLES OF THE
BATTERIES ARE INSTALLED CORRECTLY. THE INCORRECT
POLARITY OF THE BATTERIES WILL CAUSE DAMAGE TO THE
REMOTE CONTROL. LED INDICATES TRANSMITTER BATTERY
VOLTAGE STATUS, WHEN ONLY ONE LED LAMP IS ON, THE BATTERY
VOLTAGE IS LOW, PLEASE REPLACE THE BATTERY IN TIME!

Receiver
Interface
⚫Battery Switch: Control the power of the receiver;
⚫Battery interface: Battery interface for 1S Lipo;
⚫Motor interface: The connector for 180 motor.
⚫Servo interface: The connector for 5-wire servo.
⚫Charging socket：The charging interface of the receiver. The receiver is charged
by the transmitter.
Warning: Ensure that the positive and negative poles of the battery
interface are correct, and the inverse will burn out FS-GT15 RX.
Transmitter and Receiver Pairing
Please follow the following steps:
1. Open the receiver first and click the button to make the receiver enter the
binding state. The LED will blink rapidly.
2. Turn on the transmitter. The transmitter’s red LED blinks quickly, indicating
that the transmitter enters the binding state. The binding will be completed within 3s.
3. After binding successfully, the receiver’s LED will always be on.
Receiver LED light State
1. LED light stays on: transmitter and receiver has been paired, work properly.
2. LED light blinks slowly: receiver does not pick a signal from transmitter: (1).
transmitter is not on; (2). pairing has not been done yet.
3. LED light blinks once a second: battery voltage is low.

4. LED light blinks fast: under pairing mode.
Fail Safe
Fail safe feature build in receiver. When receiver stop communication with
transmitter, ESC will stop outputting, then steering channel output will maintain the
latest position.
Low Voltage Protection
The receiver has built-in low voltage protection.
If the battery voltage is less than 3.3V, the receiver enters the low voltage
protection mode and the motor output maximum speed is limited to 50%.
If the battery voltage is less than 3.1V, the motor will stop running.
Installation and Use Guide
The remote control is a 2.4G wireless products, a proper installation and usage
will exert influence on performance of the product.
Due to the poor penetration of 2.4G signals, it is necessary to ensure that
transmitters and receivers are used without occlusions in order to ensure reliable
communication;
A build-in 2.4G signal receiving module inside the receiver, so keep it away as
far as possible from other electronic products, motors, etc., to reduce interference;
The remote controller receiver and transmitter has an PCB antenna, keep any
metal materials away near the antenna.
As the radio frequency products are affected by the external environment, the
performance differences vary greatly. The main points of installation and use are to
ensure that the RF signals of the remote controller can be transmitted effectively and
reliably.
Proper installation and use are essential to ensure product performance.
Summary: FS-GT15 Rx radio system is a high performance and multiple
functions for RC cars. The built-in receiver and ESC make FS-GT15 Rx become
a high degree of integration with complex functions product, please be sure to
carefully read the user manual in using, avoid wiring error caused damage to the
product.

work normally
Battery low cut-off protect;
The connection between ESC
and motor is interrupted; The
motor is damaged
Change battery; Check the
connection between the motor
and ESC; Change battery.
The motor
accelerates
rapidly at the
startup moment,
but has lockout or
cogging problem.
The discharge capacity of the
battery is not strong enough;
The motor rotates too fast,
and the gear ratio is too
aggressive; Something wrong
with the driveline of the
vehicle.
Change a battery with better
discharge capability;
Use a motor with lower RPM,
or smaller pinion to soften the
gear ratio; Check the driveline
of the vehicle
