Note: About flying
While you are getting ready to fly, if you place your transmitter on the ground, be sure that the wind
won’t tip it over. If it is knocked over, the throttle stick may be accidentally moved, causing the
engine to speed up. Also, damage to your transmitter may occur.

Please don't fly in the rain!
Rain or moisture may enter the transmitter internal through gaps in the antenna or joystick flight
and cause your flight to instability even out of control. If inevitable will fly in the wet weather (such
as game), please be sure to use plastic bags or waterproof cloth to cover your transmitter, please
don't flight if there is lightning.

3. Preparing Before Flight
3.1 Charge
First, please keep your battery is 4.2V to ensure your F110S with enough power to fly, you can
charge your battery by CM120 if not fully charged.
Professional Designed LiPo Battery Charger CM120
Energy Supply Station
Brand new designed LiPo battery charger CM120, designed for 1S LiPo battery. Inherit the high
precision of CB86PLUS, make the charging safer, battery which charged by CM120 is more powerful
can flight about five to eight minutes.
Charging current can setup 1A or 2A by toggle the switch as you need.
Red LED indicate charging mode and green LED indicate the battery is fully charged.
CM120 use universal USB connector, so you can use computer or power bank for mobile phone as
the power supply for CM120.
Pay attention: ensure the voltage output of power supply is not higher than 5V.
3.2 Remote Controller Setup
Setup If Controlled by AT9S/AT9/AT10/AT10II
(1) Please turn on AT9S/AT9(DC 7.4~18V) or AT10/AT10II (DC 7.4~15V) first.
(2) Make sure the model type of AT9S/AT9/AT10/AT10II is multirotor model, and the
CH3(throttle) is reverse.
Setup in BASIC MENU--MODEL TYPE--MULTIROTOR
Back to BASIC MENU---REVERSE--setup 3: THRO REV

Setup in ADVANCE MENU--ATTITUDE--CH:CH5, SW3: SwC
Setup both up and center position of SwC ATTI. Model and down position STABL. mode.
AT9S/AT9/AT10/AT10II: SwC at the up position means that F110S will flight in Altitude Hold Mode
(Low-speed) and at the center position means that F110S will flight in Altitude Hold Mode
(High-speed), if SwC at the bottom position means that F110S will flight in Stabilize Mode.
Setup If Controlled by T8FB
Please turn on T8FB (DC 4.8~18V) first.
If you need change parameters, please connect T8FB and computer via a universal android USB
cable, setup details please read the T8FB user manual (you can download from our website
www.radiolink.com).
T8FB: SwB at the up position means that F110S will flight in Altitude Hold Mode (Low-speed) and at
the center position means that F110S will flight in Altitude Hold Mode (High-speed), if SwB at the

bottom position means that F110S will flight in Stabilize Mode.
3.3 Power on and Bind
3.3.1 Power On
(1) Orange propellers default indicate the head direction, if you change the propellers, you can
make sure the head direction by check the flight controller CS360(like the picture), make sure
before power F110S on.
(2) Please put the F110S on a level surface, the green LED will blink after power on about 2
seconds, do not move F110S when green LED blinking.
(3) F110S finished the calibration after green LED off.
Attention: Head direction have been determinate, if you put not same as the direction that when
you calibrate, it will back to the same direction automatically when F110S start to fly, that we called
Head Front Forward Point Without Compass.
3.3.2 Bind
F110S sells with receiver R6DSM or R8FM.
(1) Place the transmitter and the receiver close to each other within 1 meters.
(2) Turn on the transmitter, then power on the R6DSM or R8FM.
(3) Connect R6DSM or R8FM to flight controller CS360(it defaults connect).
(4) There is a black button on the R6DSM and R8FM, press the binding button twice in two seconds
and release, receiver light starts blinking, after about 8 times blinking, match code success when
receiver signal LED always on!

Attention: If your transmitter is AT10II, it will default that the channel is setup 12CH, you have to
setup channel from 12CH to 10CH in SYSTEM menu because R6DSM is a 10 channels receiver. (AT9,
AT9S and AT10 are the same)
F110S now just support S-BUS signal, both R6DSM and R8FM support S-BUS and PPM signal,
please make sure that the LED of R6DSM/R8FM is blue which shows R6DSM/R8FM output S-BUS
signals.
Both R6DSM and R8FM can recognize signal by check the bind LED. Blue/purple LED indicates S-BUS
signal and red LED indicates PPM signal.
If you need change signal from PPM to S-BUS, please short press the ID SET switch two times within
1 second, the signal is changed from SBUS to PPM. The red LED indicates the PPM and blue/purple
indicates S-BUS.
3.4 How to Disarm (Use T8FB as an example)
Throttle on left stick: move the left stick to the lower right corner, keep about 2 seconds till green
LED on.

Throttle on right stick: move the left stick to the lower right corner and the right(throttle) stick to
the lower position, keep about 2 seconds till green LED on.
Disarm Gesture
3.5 How to Arm:
Move the throttle stick to the lower position and rudder stick, keep about 2 seconds till green LED
off.
Arm Gesture
4. Low Voltage Alarm
The green LED of flight controller CS360 is blinking all the time indicate that the voltage of F110S

is lower than 3.8V (we default F110S is ready to alarm if the battery lower than 3.8V), please
prepare for charge your battery.
5. Flight Controller CS360 Introduction
The flight controller CS360 combine Kalman filtering technology with inertial navigation altitude
hold algorithm. The inertial navigation blending gyro, accelerometer and barometer make F110S
Altitude Hold stably even at the lower than one-meter altitude or faced with fluctuations in airflow.
Brand new self-developed flight controller system CS360, breaking the defects of Euler angles
singular value, using rotation vector algorithms ensure the F110S can fly with pretty high-speed
even under Altitude Hold mode.
The power supply of CS360 support 1S(4.2V).
When use 1S battery: the camera will have powered by the 1S battery directly.
Size of PCBA: 21*32* 1.2mm.
6. Read Before Use F110S
6.1 Read Before Start to Flight in Stabilize Mode
(1) Please keep the throttle stick smoothly to avoid F110S suddenly drastically up and down.
(2) Put the throttle stick to the lower position immediately to let motor stop work when F110S
knock something.
(3) Let the motor be perpendicular to F110S plate.
6.2 Read Before try the Throw and Fly Mode
(1) Make sure you can control F110S skillful and at a pretty wide-open space to try the Throw and
Fly Mode.
(2) Make sure the head direction and then throw and fly the F110S.
(3) Push the throttle stick when throw your F110S out sand try your best throw it upward.
(4) F110S can correct attitude and direction automatically. If you throw F110S too hard, it may fly to
a direction all the time because of the inertia, you can correct the direction by move sticks.
7. Flight Mode
F110S is default three flight modes. RC freshman can practice from Altitude Hold Mode (High-speed)
-- Altitude Hold Mode (Low-speed)—Stabilize Mode, easy to achieve from beginner to professor.
7.1 Altitude Hold Mode (Low-speed)
AT9S/AT9/AT10/AT10II: Move SwC to the up position that keeps F110S work in Altitude Hold Mode

(Low-speed).
T8FB: Move SwB to the up position that keeps F110S work in Altitude Hold Mode (Low-speed).
7.2 Altitude Hold Mode (High-speed)
AT9S/AT9/AT10/AT10II: Move SwC to the center position that keeps F110S work in Altitude Hold
Mode (High-speed).
T8FB: Move SwB to the center position that keeps F110S work in Altitude Hold Mode (High-speed).
7.3 Stabilize Mode
AT9S/AT9/AT10/AT10II: Move SwC to the bottom position that keep F110S work in Stabilize Mode.
T8FB: Move SwB to the bottom position that keep F110S work in Stabilize Mode.
Altitude Hold Mode (Low-speed) will slower and with less angular variation when flight than
Altitude Hold Mode (High-speed) and Altitude Hold Mode (High-speed) slower and with less angular
variation when flight than Stabilize Mode.
Suggest that RC beginners practice with Altitude Hold Mode (Low-speed) at the very begging.
8. Calibration
Level calibration have finished when you received the F110S, you can re-calibrate if you need.
Level Calibration: Please put the F110S on a level surface, the left stick to the lower left position
and the right stick to the lower right position, keep about 3 seconds, the green LED will blink once,
then calibrate success.
