Description

The FS-iA6B receiver utilizes GFSK modulation across 140 bands within the 2.4055–2.475 GHz spectrum, providing robust RF performance with a sensitivity of -105 dBm. Its dual-antenna design significantly improves signal reception and reduces the risk of failsafes in complex RF environments typical of FPV flying.

Engineered for flight controller integration, it outputs both traditional PPM and the faster, digital iBus protocol, allowing for direct connection to Betaflight, iNAV, or ArduPilot autopilots. The low-profile, end-pin connector layout simplifies wiring in constrained spaces common in mini-quad and fixed-wing builds.

Key Features

  • AFHDS 2A Protocol: Second-generation automatic frequency-hopping digital system for stable, low-latency control link.
  • Dual-Antenna Diversity: Two independent 26mm antennas provide superior signal reception and multipath rejection.
  • Flexible Output Modes: Supports both PPM (summed signal) and digital iBus serial output for direct flight controller connection.
  • Broad Voltage Compatibility: Operates from 4.0V to 8.4V, supporting direct power from a wide range of LiPo batteries and BECs.
  • Compact, Low-Weight Design: Minimal footprint (47 x 26.2 x 15mm) and light weight (14.9g) minimize impact on drone CG and build space.
  • Easy Binding Process: Simple bind-plug procedure for quick pairing with compatible FlySky transmitters.

Applications

  • FPV racing and freestyle quadcopters requiring a reliable, low-latency control link.
  • DIY drone and multirotor builds using Betaflight, iNAV, or ArduPilot flight controllers.
  • Fixed-wing aircraft and gliders compatible with PPM or serial receiver input.
  • Scale model airplanes and helicopters operating within the 2.4GHz AFHDS 2A ecosystem.
  • Educational and robotics platforms needing a simple, multi-channel radio control interface.

Frequently Asked Questions

What transmitters are compatible with the FlySky FS-iA6B receiver?

The FS-iA6B is compatible with FlySky transmitters using the AFHDS 2A protocol, including the FS-i4, FS-i6, FS-i10, FS-GT2E, and FS-GT2G. It will not bind with older AFHDS protocol radios or systems from other brands like FrSky or Spektrum.

Can I connect the FS-iA6B directly to a Betaflight flight controller?

Yes. You can connect it using either the PPM output (single signal wire) or the iBus serial output. For iBus, connect the signal wire to a free UART RX pad on your FC, then configure the corresponding port in Betaflight Configurator for 'Serial-based receiver' and 'FlySky iBus' as the protocol.

What is the operating voltage range, and can I power it directly from a LiPo?

The receiver operates from 4.0V to 8.4V. This means you can power it directly from a 1S LiPo (3.7V nominal, ~4.2V full) or a 2S LiPo (7.4V nominal, ~8.4V full), or from any regulated 5V BEC on your ESC or PDB. Do not exceed 8.4V.

What is the advantage of the iBus output over standard PWM or PPM?

iBus is a digital serial protocol that sends all channel data over a single wire at a much higher speed and lower latency compared to PPM. It provides more reliable signal transmission, allows for two-way telemetry (if supported by your transmitter), and uses fewer pins on your flight controller.
