SAFETY PRECAUTIONS
Never operate models during adverse weather conditions. Poor visibility can cause
disorientation and loss of control of pilots model.
Never use this product in a crowd or illegal areas.
Make sure no props installed when setting parameters of Mini Pix (the flight controller) on
Mission Planner (MP) or calibrating ESC.
Always ensure the trim levers at 0 and battery properly charged before connecting the
receiver.
Always check all servos and their connections prior to each run.
Stay at a certain distance from the aircraft during flight to avoid getting hurt by the
components of high-speed rotation (eg. Props, brushless motors)
After landing off, make sure the aircraft is disarmed and props have stopped moving before
getting close to touch the aircraft.
Always be sure about turning off the receiver before the transmitter.
When removing battery, NEVER pull the wires but please do press the yellow port with one
hand and pull the other yellow port with another. If the wrapping materials damaged , the
bare wires may cause DANGER.
Follow the instructions of props installation in case of dropping during flight.
To ensure the best radio communication, please enjoy the flight at the space without

WARNING
This product is not a toy and is NOT suitable for children under the age of 18. Adults should
keep the product out of the reach of children and exercise caution when operating this product in
the presence of children.
Water or moisture may enter the transmitter inside through gaps in the antenna or joystick
and cause model instability, even out of control. If running in the wet weather(such as game) is
inevitable, always use plastic bags or waterproof cloth to cover the transmitter.

Chapter 1 Features Highlights of F110S
As the only micro racing drone that fly at high speed at Altitude Hold Mode, F110S is very easy to
master for drone freshman. The inertial navigation system technology blending Kalman filtering,
gyro, accelerometer and barometer makes F110S possible to flight through narrow space with
accuracy and hold altitude no matter close to surface (less than one-meter height) or at high speed.
With three flight modes Alt-Hold at low speed, Alt-Hold at high speed and Stabilize, beginners can
flight stably at the first trial.
(1) Remains stable even facing with sudden airflow fluctuations such as during takeoff, under
braking, or after extended flying.
(2) Can be thrown and start to fly in any angle even under high-speed.
(3) Without compass locking, F110S always automatically modify angles during flight .
(4) Monitored by Radiolink brand new mini racing drone flight controller CS360, which is different
from other flight controllers that need to set PID tuning before use,will tune automatically.
(5) Assembled as building blocks makes the RC students exercise their DIY ability and free from
lengthy mobile games.
(6) The software noise reduction technology not only enables a more pleasant flight but also
makes the motors more responsive and more efficient than traditional 8520 coreless motors.
Chapter 2 Before Flight
2.1 Power Supply
Power for transmitter T8FB: T8FB supports 4 pieces AA batteries or 2S to 4S LiPo battery. Make
sure the battery is fully charged before using them/it to power on T8FB.

Power for F110S: The voltage of 1S LiPo battery packed with F110S by default is not fully charged
so the battery needs to be charged with the charger CM120 before flight.
The LiPo battery charger CM120, specially designed for 1S LiPo battery, sharing the professional
development and high precision of CB86PLUS, ensures safer charging and battery life span.
Charging current can be set as 1A or 2A by toggling the switch at the side of the charger.
Red LED indicates the battery is under charging and green LED indicates the battery is fully
charged.
CM120 applies general USB connector, both computer and power bank for mobile phone can be
used with CM120.
Note Voltage output of power supply should be NO higher than 5V.
2.2 Remote Controller
Note The below example takes RadioLink radio T8FB Mode 2 (Throttle on the left stick) .
The two joysticks of T8FB correspond to the four basic channels respectively .
Left stick
Make the F110S rise or descend by pushing the left stick vertically upward or downward while
make the F110S rotates clockwise or anticlockwise by pushing the left stick to the left or right.
Right stick
Make the F110S flight forward or backward by pushing the right stick vertically upward or
downward while make the F110S flight towards to left or right by pushing the right stick to the left
level or right.

Assembled as building block makes the RC students exercise their DIY ability and free from lengthy
mobile games.
Learning knowledge of science and technology when assembling, setting parameters and flight.
2.4 RC Joysticks & Flight Movements
A. Throttle: Upward/ Downward/Hover
Push the Throttle Stick (on the left) vertically upward and F110S will rise while if push the Throttle
Stick (on the left) vertically downward, then the F110S will descend.
If at Alt-Hold Mode, push the Throttle Stick vertically upward till the F110S flight at the preferred height ,
then toggle the Throttle stick back the center position and release , the F110S will remain at this height.
Note Hovering is also called Altitude Hold, which can be only realized under the Alt-Hold Mode both
either at low speed or high speed. BUT NOT STABILIZE MODE.

Push the Aileron Stick (on the right) to the left and F110S will flight towards to left while if push the
Aileron Stick (on the right) to the right, then the F110S will flight towards to right.
Chapter 3 Get Ready to Flight
3.1 Propellers Installation
F110S is packed with propellers protection cover by factory default. To install the
protection cover, propellers need to uninstall first. Or after a period of flight, the default propellers
may get worn and needs to be uninstalled to change with spare/backup new ones. It is important
to well identify the propellers of positive/clockwise and negative/anticlockwise rotation. If installed
incorrectly, F110S can’t take off even the throttle is pushed to max.
In order to identify the propellers rotation, take a propeller and
observe there’s a radian at both sides of the small cylinder in the
middle. The higher part (also called windward side) of the right
propeller is at the front and the rotating motor will make propeller
rotate anticlockwise. On the contrary, that is clockwise rotation.
