The FlySky FS-i6 is a popular and budget-friendly 2.4GHz RC transmitter paired with the FS-iA6B 6-channel receiver, widely used in RC planes, drones, boats, cars, and DIY robotics projects. It offers stable long-range control using AFHDS 2A technology, along with multiple mixing features, trims, and customizable settings. The receiver supports PPM and i-BUS output, making it very useful for Arduino / flight controller / robotics signal interfacing.
Core Module Features
• System: FlySky AFHDS 2A (2.4GHz spread spectrum)
• Channels: 6CH transmitter + 6CH receiver
• Output Type: PWM / PPM / i-BUS (receiver dependent)
• Display: LCD screen for settings & calibration
• Control Inputs: 2 joysticks + trims + switches
Electrical & Interface
• Transmitter Power: Battery powered (commonly 4× AA cells)
• Receiver Supply Voltage: 4V – 6.5V (typical RC range)
• Receiver Output:
• 6× PWM channel outputs
• PPM output (single wire combined signal)
• i-BUS output (digital serial bus)
• Antenna: Built-in antenna on transmitter + dual antenna on receiver
Performance & Connectivity
• Stable 2.4GHz control with good interference resistance
• Smooth signal response for RC control
• Long control range (ideal for hobby RC use)
• Supports model memory (store multiple configurations)
• Useful for flight controllers like APM / Pixhawk (via PPM/iBUS)
Physical & Integration
• Ergonomic handheld transmitter design
• FS-iA6B receiver has compact design with multiple output pins
• Easy to connect with servos, ESCs, and RC controllers
• PPM output makes wiring simple for drones/robotics
Applications
• RC Airplanes / Gliders
• RC Cars and Boats
• Drone / Quadcopter control
• Robotics and remote control projects
• Arduino / ESP32 RC input reading via PPM/iBUS
Pro Tip
• Use PPM output for controlling a drone/robot with fewer wires
• For Arduino projects, i-BUS is best (more stable + multiple channels over 1 signal wire)
• Always bind receiver to transmitter before use
• Keep receiver antenna away from motors/ESC wires for better range
