• Misuse of this product may lead to serious injury or death. To ensure the safety of you
and your equipment, read this manual and follow the instructions.
• Make sure the product is properly installed in your model. Failure to do so may result in
serious injury.
• Make sure to disconnect the receiver battery before turning o the transmitter. Failure
to do so may lead to unintended operation and cause an accident.
• Ensure that all motors operate in the correct direction. If not, adjust the direction rst.
• Make sure the model ies within a certain distance. Otherwise, it would cause loss of
control.
• Do not use the product at night or in bad weather like rain or thunderstorm. It can
cause erratic operation or loss of control.
• Do not use the product when visibility is limited.
• Do not use the product on rain or snow days. Any exposure to moisture (water or snow)
may cause erratic operation or loss of control.
• Interference may cause loss of control. To ensure the safety of you and others, do not
operate in the following places:
• Near any site where other radio control activity may occur
• Near power lines or communication broadcasting antennas
• Near people or roads
• On any body of water when passenger boats are present
• Do not use this product when you are tired, uncomfortable, or under the inuence of
alcohol or drugs. Doing so may cause serious injury to yourself or others.
• The 2.4GHz radio band is limited to line of sight. Always keep your model in sight as a
large object can block the RF signal and lead to loss of control.
• Never grip the transmitter antenna during operation. It signicantly degrades signal
quality and strength and may cause loss of control.
• Do not touch any part of the model that may generate heat during operation, or
immediately after use. The engine, motor or speed control, may be very hot and can
cause serious burns.

FS-l6S
2. Introduction
The FS-i6S transmitter and iA6B receiver constitute a 6 channel 2.4GHz AFHDS 2A digital proportional
computerized R/C system. This system supports quadcopter.
2.1 System Features
The AFHDS 2A (Automatic Frequency Hopping Digital System Second Generation) developed and patented by
FLYSKY is specially developed for all radio control models. Oering superior protection against interference
while maintaining lower power consumption and high reliable receiver sensitivity, FLYSKY's AFHDS technology is
considered to be one of the leaders in the RC market today.
Bidirectional Communication
Capable of sending and receiving data, each transmitter is capable of receiving data from
temperature, altitude and many other types of sensors, servo calibration and i-BUS Support.
Multi-channel Hopping Frequency
This systems bandwidth ranges from 2.4055GHz to 2.475GHz. This band is divided in 140 channels.
Each transmitter hops between 16 channels (32 for Japanese and Korean versions) in order to
reduce interference from other transmitters.
Omni-directional Gain Antenna
The high eciency Omni-directional high gain antenna cuts down on interference, while using less
power and maintaining a strong reliable connection.
Unique ID Recognition System
Each transmitter and receiver has it's own unique ID. Once the transmitter and receiver have
been paired, they will only communicate with each other, preventing other systems accidentally
connecting to or interfering with the systems operation.
Low Power Consumption
The system is built using highly sensitive low power consumption components, maintaining high
receiver sensitivity, while consuming as little as one tenth the power of a standard FM system,
dramatically extending battery life.

The status indicator is used to indicate the power and working status of the transmitter.
• O: The transmitter is powered o.
• Blue light: The transmitter is on and working.
2.2.10 PS/2 Port
This port enables PPM output.
2.2.9 USB Simulatior Function
The system can be connected via a USB cable to a computer for use as a HID device. This function is automatically
activated when connected to a computer and will be recognised as a standard HID controller.
Caution • If the computer does not recognise the transmitter unplug and reconnect the USB
cable.
