FLY SKY FS IA6B RF 2.4GHz 6CH Receiver

The Flysky 4.0-8.4V/DC 2.4GHz 6-channel receiver is a popular choice for RC vehicles, such as drones, planes, cars, and boats. This type of receiver is typically compatible with Flysky's AFHDS 2A (Automatic Frequency Hopping Digital System 2A) protocol, which provides reliable 2.4GHz communication, essential for remote control projects. Here is an overview of its features, specifications, and usage.

Key Features:

• Voltage Range: Operates between 4.0V and 8.4V DC, allowing compatibility with a wide range of battery types, including 1S to 2S LiPo batteries (3.7V to 8.4V).

• Frequency: 2.4GHz (AFHDS 2A protocol), ensuring stable communication with minimal interference.

• Channels: 6 PWM channels for controlling various RC functions (e.g., throttle, ailerons, elevators, steering).

• Range: Typical range of 300-500 meters depending on the transmitter and environmental conditions.

• PPM/i-BUS Support: Enables connecting the receiver to flight controllers via a single wire for signal transmission, reducing wiring complexity.

Specifications:

• Modulation: GFSK (Gaussian Frequency Shift Keying)

• Communication Protocol: AFHDS 2A

• Number of Channels: 6 PWM (can also output PPM or i-BUS for flight controllers)

• Input Voltage: 4.0V - 8.4V DC

• Operating Current: <30mA

• Antenna: Dual antennas for increased reception

• Dimensions: Approximately 40mm x 21mm x 7mm (depending on model)

• Weight: 10-15g

Receiver Pinout:

• CH1 - CH6: These channels output PWM signals for servos, ESCs (Electronic Speed Controllers), or other components.

• VCC/GND: Power and ground pins, typically powered by the BEC (Battery Elimination Circuit) from an ESC or a dedicated power supply.

• i-BUS/PPM port: Used to send combined channel data to a flight controller via PPM or i-BUS protocol.

Common Compatible Flysky Transmitters:

• FS-i6

• FS-i6X

• FS-T6

• FS-i10

• FS-GT5 (for RC cars and boats)

Usage and Setup:

1. Powering the Receiver:

• The receiver can be powered from a voltage source in the range of 4.0-8.4V DC.

2. Binding the Receiver to a Transmitter:

Binding is the process of pairing the receiver with the transmitter so they can communicate.

• Steps for Binding:

  1. Turn on your Flysky transmitter and go to the RX Bind setting.

  2. Press and hold the bind button on the receiver (usually a small recessed button).

  3. While holding the bind button, apply power to the receiver. The LED on the receiver should blink, indicating it's in bind mode.

  4. On the transmitter, press Bind.

  5. The receiver’s LED will stop blinking and remain solid when successfully bound.

  6. Turn off both the transmitter and receiver, then turn them back on to confirm the connection.

3. Connecting to Flight Controllers:

The receiver can be connected to flight controllers such as those used in drones and planes.

• PPM Mode: Connect the PPM signal wire to the flight controller’s PPM input. PPM mode sends all six channels over a single wire, simplifying the connection.

• i-BUS Mode: If your flight controller supports i-BUS, use the i-BUS output for telemetry and advanced communication features.

4. Fail-Safe Configuration:

Fail-safe is an important feature for safety. If the receiver loses signal from the transmitter, fail-safe allows you to specify what happens to the channels (e.g., cut throttle).

• Setting Fail-Safe:

  1. Bind the receiver to the transmitter.

  2. On the transmitter, go to the Fail-Safe settings in the menu.

  3. Configure each channel to either Hold, No Output, or a specific position.

  4. Test the fail-safe by turning off the transmitter to ensure the receiver behaves as expected when the signal is lost.

5. Connecting to Servos or ESCs (PWM Mode):

In PWM mode, each channel outputs an individual signal for controlling a servo or ESC.

• CH1: Typically used for throttle (in RC planes or drones) or steering (in RC cars).

• CH2-CH6: Can be used for rudder, ailerons, elevator, or other functions like flaps, landing gear, or lights.

The servos or ESCs are connected to the receiver using standard 3-wire connectors (signal, VCC, and ground).

Applications:

1. Drones and Quadcopters:

The Flysky 6-channel receiver can be connected to a drone’s flight controller (e.g., Betaflight, INAV, or Pixhawk) via PPM or i-BUS. This simplifies wiring and provides enough channels to control various drone functions (throttle, pitch, roll, yaw, and auxiliary functions like cameras or lights).

2. Fixed-Wing RC Aircraft:

In planes, the receiver is used to control the throttle, rudder, ailerons, and elevator. The additional channels can be used for landing gear, flaps, or other accessories.

3. RC Cars and Boats:

In RC cars, CH1 is used for steering and CH2 for throttle. The other channels can be assigned to additional functions like lights or winches. In RC boats, similar channel assignments are used for throttle and steering, with the possibility of adding extra features like water pumps or lights.

Example Setup:

Let’s say you are building a quadcopter using a Flysky FS-i6X transmitter and the Flysky 4.0-8.4V 2.4GHz 6-channel receiver. Here's how the setup would go:

1. Powering the receiver: Use the BEC from your ESC to supply 5V to the receiver's VCC and GND pins.

2. Binding the receiver: Follow the binding steps above to pair the receiver with your transmitter.

3. Connecting to flight controller: Use the i-BUS connection to link the receiver to the flight controller (e.g., Betaflight).

4. Setting fail-safe: Configure fail-safe to ensure the motors stop in case of signal loss.

5. Flight control: Use channels 1-4 for controlling throttle, yaw, pitch, and roll. Use channels 5-6 for auxiliary functions like controlling the camera or activating LEDs.
