The transmitter and receiver have already been bound at the factory.
1. Turn on the transmitter while holding the bind button to enter bind mode. G.LED will start
flashing quickly.
• Once in bind mode release the bind button.
2. The receiver will enter bind mode atomically when powered on.
3. Once binding is successful the receiver’s LED will flash slowly and the transmitter’s LED
will remain solid after being rebooted.
Note: When binding, put the transmitter into bind mode first, then the receiver.
4.1 Power On
However if the receiver needs to be replaced or additional receivers bound follow these steps:
Note • Operate with caution in order to avoid damage or injury.
Note • Makesurethatthethrottleisatitslowestpositionandtheswitchesaresettotheirup
position.
• applicable to the FS-G4P transmitter and the FR-R4P receiver. Different receivers have
different bind procedures. For more information visit the FLYSKY website for manuals and
other related information.
• Product information is updated regularly, please visit our website for more information.

4.3 Stick Calibration
This function is used to set the neutral position for throttle and wheel.
Every transmitter is calibrated before leaving the factory, however if recalibration is required,
please follow these steps:
1. Turn and hold the wheel as far clockwise as it will turn, hold the throttle all the way forward,
then turn on the transmitter in calibration mode.
• The R.LED and G.LED will 󽗊ash twice.
2. Calibrate wheel: Turn the wheel completely clockwise, then completely counterclockwise.
• When calibration is completed the R.LED will be o󽗈.
3. Trigger calibration: Pull the trigger back then forward as far as it will go.
• When calibration is completed the G.LED will be o󽗈.
4. Once calibration is complete press the bind key to save and exit.
4.4 Power O󽗈
Danger • Make sure to disconnect the receiver power before turning o󽗈 the transmitter. Failure
to do so may lead to damage or serious injury.
Follow the steps below to turn off the system:
1. Disconnect the receiver power.
2. Toggle the transmitter's power switch to the off position.

5.System Functions
This section focuses on the functions and how to use them.
5.1 Channel Description
5.2 Channel Reverse
The transmitter outputs a total of 4 channels, which are allocated as follows:
• CH1：Steering Wheel
• CH2：Throttle Trigger
• CH3：Three-position Switch
• CH4：Reset Button
Note: By default the output of CH4 is 1000us, after which pressing the button will toggle between
1000 and 2000us.
5.3 Trims
This function is used to adjust each channels direction of movement in relation to it’s input.
The ST.REV / TH.REV switches are the reverse buttons for CH1 and CH2. If the switch is up it
indicates reverse, and the down indicates normal.
The ST.TRIM is the trims for CH1 (steering),and can be multiplexed as Trims of CH3 and CH4.
For multiplexing switching mode, see [5.5 Mode Switching].
TH.TRIMis the trims for CH2(throttle).
Adjustment range: -120us- + 120us, each step is 4us;
ST.TRIM + / TH.TRIM +: increase adjustment step;
ST.TRIM- / TH.TRIM-: Decrease adjustment step.
LED Indicator:
• When using the trim keys the G.LED will 󽗊ash slowly on short presses and quickly on long presses.
• When the 󽗉ne adjustment value is at the midpoint, the G.LED will 󽗊ash twice slowly.
• When the 󽗉ne adjustment value is at both ends (+ 120us / -120us), the trim adjustment is at its maximum and as
such G.LED will not 󽗊ash(if the 󽗉ne adjustment value has been adjusted to + 120us, then press ST.TRIM + / TH.TRIM
+ key is invalid and G.LED has Instructions)

9
5.4 D/R
ST.D / R is for servo travel adjustment, which can be multiplexed as CH2 (throttle), CH3, CH4
servo travel adjustment, see [5.5 Mode Switch] for multiplex switching mode;
Adjustment range: 0-120%(the default is 100%), the step is 5%.
ST.D / R +: increase servo travel.
ST.D / R -: decrease servo travel.
LED Indicator:
• When using the trim keys the G.LED will 󽗊ash slowly on short presses and quickly on long presses.
• When the ratio value is at both ends (0/120%), the ST.D / R button is at its maximum and as such G.LED will not
󽗊ash(if the ratio value has been adjusted to 120%, then press ST.D/R+ key is invalid and G.LED has Instructions)
5.5 Mode switching
This function is for reusing the ST.TRIM and ST.D / R buttons for different channels (see [5.3
Trims], [5.4 D/R).
Function setting:
Under normal power-on, quickly press the Bind button twice (within 1 Sec) to cycle
through modes 1, 2, 3, and 4. The default setting when powering on is mode 1.
Mode 1: G.LED flashes slowly once, ST.TRIM is CH1 fine adjustment, ST.D / R is servo travel
adjustment.
Mode 2: G.LED flashes twice slowly, ST.TRIM is CH1 fine adjustment, ST.D / R is CH2 servo travel
adjustment.
Mode 3: G.LED flashes three times slowly, ST.TRIM is CH3 fine adjustment, ST.D / R is CH3 servo
travel adjustment.
Mode 4: G.LED flashes slowly four times, ST.TRIM is CH4 fine adjustment, ST.D / R is CH4 servo
travel adjustment.
This function dictates what the receiver will do in the event that it loses signal from the
transmitter, this includes servo position etc.
Setup:
1. Turn on the transmitter and make sure it is connected to the receiver.
2. Hold the control surface at the desired failsafe position.
3. Press and hold the bind button for 3 seconds, if the G.LED starts flashing every 2 seconds then
setup has been successful.
Failsafe is now set and will default to these values when the receiver looses signal.
Note: The fail-safe function has no default set at the factory and as such must be set manually.
If no failsafe setting has been set, then the receiver will not output anything when signal is
lost.

Beginner mode is designed for people new to the hobby.
In this mode the throttle will be limited to 50 percent, The channel range defaults to
1250~1500~1750us.
Setup:
To switch between beginner and normal modes press and hold the channel 4 button as the
transmitter is turned on.
Note: By default, the system is set to normal mode. The GLED will flash slowly for 3 seconds
during power on if the system is set to beginner mode.
