Digital Proportional Radio Control System
2. Introduction
The FS-i6 transmitter and FS-iA6 receiver constitute a 6-channel 2.4GHz AFHDS 2A digital proportional
computerized R/C system. It is compatible with fixed-wing,glider and helicopters.
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. Offering 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 efficiency 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.

Dual rate/exp.
The dual rate/exp. function only applies to channels 1,2,4.
Dual Rate: Dual Rate reduces or increases the difference between the highest and lowest possible value,
for example if applied to the rudder, (set to a throw of 10cm) before changing the settings, when you
move your stick to 1/2 you would get 5cm rudder movement, if you move the stick 1/4 of the way, the
rudder will move 2.5cm, so at 100% there is a direct, linear relationship of stick movement and surface
movement.
If a setting of 50% is entered then moving the stick all the way in one direction will only give 1/2 of the
surface movement and 1/2 stick movement will only produce 1/4 surface movement, this has the effect
of reducing how responsive the rudder is when the stick is moved, effectively reducing the range of
movement available to the servo. This function is usually assigned to a condition so that it can be turned
on and off during flight.
Exp. (Exponential) Exponential changes the relationship between stick movement and surface movement
by creating a curve, when in use the stick movement and surface movement are no longer linear so the
stick has a different response in different at different positions. For example this is useful when needing
less reaction during a take-off but more reaction when in the ai r.

3. Hold the "CANCEL" key to save and return to the previous menu.
4. To return a setting to default, press and hold the "OK" key for 3 seconds. Press and hold the
"CANCEL" key to save.
5.8 Throttle curve
This function enables the user to adjust the ratio between stick and servo movement using a linear line
or non-linear curves.
This is useful when wanting to change how the throttle reacts at between different stick positions, for
example having a smaller throttle change when the stick is between 0-30%, then a larger throttle change
between 30% and 100%. If your models throttle is not linear, it is also possible to use this function to
create a more linear movement.
This function uses 5 points to change the throttle curve, L being the low and H being the high.
