Description

The FlySky FS-i4X transmitter and FS-A6 receiver combo forms a complete radio control system built on the advanced AFHDS 2A protocol. This system utilizes a unique ID binding process between transmitter and receiver, ensuring secure communication and high immunity to external signal interference. The design incorporates low-power electronic components and intermittent RF modulation to optimize battery life while maintaining a robust communication link.

Engineered for versatility, the system is compatible with a wide range of models including fixed-wing aircraft, gliders, helicopters, and multirotor drones. The transmitter’s ergonomic layout and LED indicators provide clear status feedback, while the included 6-channel receiver offers ample control for basic to intermediate aerial platforms, supporting a voltage input range of 4.0-6.5V DC.

Key Features

  • AFHDS 2A protocol ensures stable, long-range transmission with built-in error correction.
  • High-gain, multi-directional antenna system covering the full 2.405-2.475 GHz band.
  • V-MIX mixing system allows for advanced channel configuration and model customization.
  • Low-power consumption design with sensitive receiver chip for extended operational time.
  • Durable plastic construction with a compact form factor for comfortable handling.
  • Mode 2 (left-hand throttle) default configuration, ideal for multirotor and airplane pilots.

Applications

  • Entry-level and intermediate FPV racing or freestyle drone builds requiring a reliable 4-6 channel control link.
  • RC airplane and glider pilots seeking an affordable AFHDS 2A protocol system with expansion capabilities.
  • Scale helicopter and multirotor projects where the 6-channel receiver provides sufficient control surfaces.
  • DIY drone and robotics platforms needing a customizable radio link with V-MIX channel mixing.
  • Educational and club environments where multiple transmitters must operate simultaneously without interference.

Frequently Asked Questions

What is the AFHDS 2A protocol and what are its advantages?

AFHDS 2A (Advanced Frequency Hopping Digital System 2A) is FlySky's 2.4GHz protocol featuring automatic frequency hopping across 140 channels. Its primary advantages include strong anti-interference capability, allowing multiple pilots to operate simultaneously without signal clash, and built-in error correction for stable, long-range control links ideal for FPV and RC aircraft.

Can I use this FlySky FS-i4X transmitter with other receivers?

Yes, the FS-i4X transmitter is compatible with any FlySky receiver that supports the AFHDS or AFHDS 2A protocol. You must ensure the receiver's protocol matches and follow the standard binding procedure. The included FS-A6 receiver is bound from the factory, but you can bind additional compatible receivers to the same transmitter.

What type of batteries does the FS-i4X transmitter require and how is the low-voltage warning activated?

The transmitter requires 4 x AA batteries (1.5V each) for a total of 6V DC. The system includes a low-voltage warning that activates when the battery level drops below approximately 4.2V, indicated via the LED display to alert the pilot before a loss of control occurs.

Is the throttle stick on the left or right side (Mode 1 vs. Mode 2)?

The FlySky FS-i4X comes configured in Mode 2 by default, which places the throttle stick on the left side and the pitch/roll control on the right stick. This is the standard configuration for multirotor drones and airplane pilots in many regions.
