FEATURES DESCRIPTIONS
WARNING
FS-2REE is a highly-integrated multifunction ESC, it has built in brush ESC,
Page 2
BEC and 2 channel receiver functions inside the receiver. It must work with right
motor in order to get FS-2REE work properly. If other types motor need to use with
FS-2REE, we highly recommend follow the operating voltage, electricity current and
power output from the user’s guide. Otherwise it will break the FS-2REE.
BEC electricity current up to 3A and 5V output voltage. If any other connected
electronic equipment with exceed the max electricity current usage, the BEC will be
damaged.
Exceed the max electricity current of the brush ESC is prohibited, it will damage
the ESC.

WARNING：ONLY ALKALINE BATTERIES CAN BE USED. MAKE SURE
MATCH THE POLARITY (+/-) AS SHOWN ON THE BATTERIES.
INCORRECT INSTALLATION OF BATTERIES WILL HARM THE RADIO
SYSTEM.

ON/OFF：Battery switch.
+/-：Battery connector, range 6-12.6V.
M+/M-：Motor connector. Max current 60A.
ST：Steering signal output, it provides steering engine power supply and PWM
signal.
TH：Throttle signal output and bind set, it provides power supply and throttle
PWM signal.
LiPo | NiMH：Battery type selection between Lipo and NiMH.
Fwd/Rr/Bev | Fwd/Rev：Running mode selection between Fwd/Rr/Bev and
Fwd/Rev.
Set the Parameters
Using the jumper cap to set running mode and battery type.
Battery Type: LiPo/NiMH，the “LiPo” is the default option。
Running Mode： Fwd/Rev/Br and Fwd/Rev. The “Fwd/Rev/Br” is the default
option.
Fwd=Forward, Br=Brake, Rev=Reverse
The“Fwd / Br / Rev” mode indicates the vehicle can go forward, backward and
brake. This mode uses “Double-click” method to make the vehicle reverse. When
moving the throttle stick from the neutral zone to backward zone for the 1st time, the
ESC begins to brake the motor and the motor slows down and stop, so the backward
action is NOT performed immediately. When the throttle stick is moved to the
backward zone again, the backward action will happen.
The “Fwd / Rev” mode uses “Single-click” method to make the vehicle reverse,
when moving the throttle stick from neutral zone to backward zone, the vehicle
reverses immediately, so this mode is usually used for rock crawler.
Transmitter and Receiver Pairing
Transmitter has been already paired with receiver and ready to use. If user is
Page 5
going to replace for the receiver, follow the steps below for the pairing:
Turn on transmitter. Connect the “S” and “-” of TH channel output. Then turn on
the receiver, the LED light on the receiver should be fast blink, within 5 seconds LED
light should stay on, pairing complete.
Receiver LED light State
1. LED light stays on: transmitter and receiver has been paired, work properly.
2. LED light off: receiver does not pick a signal from transmitter: 1. transmitter is not
on; 2. pairing has not been done yet.
3. LDE light blink once a second: battery voltage is low.
4. LED light keeps fast blink: under pairing mode.
Beep Meaning
1 Short beep: The battery is NiMH.
2 short beeps: The battery is 2S Lipo.
3 short beeps: The battery is 3S Lipo.
1 long beep: the ESC is ready to run.
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 Warning
Low voltage warning feature build in receiver.
If the voltage of battery is lower than 3.3V per series(LiPo) or 5.3V total(NiMH),
the ESC will enter the protection mode, so the motor max speed will be limited to
50%.
If the voltage of battery is lower than 3 V per series(LiPo) or 5V total(NiMH),
the car will stop.
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;
A build-in antenna is inside the transmitter of the remote controller. The antenna is
vertically installed. So keep the remote controller in a vertical position when using;
The remote controller receiver has an antenna, ensure that the antenna keep vertical
position to the ground during the installation, and 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-2EE radio system is a high performance and multiple
functions for RC cars. The built-in receiver and ESC make FS-2EE 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.
