Description

The FlySky FS-A8S Rev 2 receiver is engineered for drone pilots prioritizing weight savings and component miniaturization without sacrificing radio link reliability. Its AFHDS 2A 2.4GHz system employs automatic frequency hopping across 135 bands to maintain a stable connection in noisy RF environments, crucial for FPV racing and freestyle applications.

This one-way receiver provides versatile signal output through its SC port, supporting both traditional PPM for basic channel control and the digital i-BUS protocol for higher channel count and faster data transmission to compatible flight controllers. The unit’s low current consumption of 40mA ensures minimal drain on the aircraft’s power system.

Key Features

  • AFHDS 2A 2.4GHz System: Utilizes advanced frequency hopping spread spectrum for robust interference resistance and stable control.
  • Multi-Protocol Output Port (SC): Single port configurable for PPM, i-BUS, or S.BUS signal output, offering broad flight controller compatibility.
  • Optimized Power Profile: Operates from 4.0-8.4V with low 40mA draw, making it suitable for direct connection to 5V BECs or 1S LiPo setups.
  • High-Density Design: Extremely small form factor and sub-2g weight minimize impact on the drone's center of gravity and overall mass.
  • Integrated 90mm Antenna: Includes a flexible wire antenna for optimal polarization and signal reception in compact frame installations.

Applications

  • Ultra-lightweight 2-inch to 3-inch micro FPV and Tiny Whoop drone builds.
  • FPV racing drones where every gram saved translates to higher thrust-to-weight ratios and agility.
  • Compact freestyle and cinewhoop builds requiring a reliable control link with minimal wiring clutter.
  • DIY micro drone and rover projects where space is extremely limited and a simple PPM signal is sufficient.
  • Backup or secondary receiver in larger models where redundancy or a dedicated payload control channel is needed.

Frequently Asked Questions

What FlySky transmitters are compatible with the FS-A8S Rev 2 receiver?

The FS-A8S Rev 2 is compatible with any FlySky transmitter that supports the AFHDS 2A protocol, such as the FlySky FS-i6, FS-i6X, FS-i10, and newer models. Ensure your transmitter's firmware is set to AFHDS 2A mode for binding and operation.

Can I use the i-BUS output with Betaflight or ArduPilot?

Yes, the i-BUS digital output is fully supported by Betaflight, iNAV, and ArduPilot flight controller firmware. You must connect the receiver's signal wire to a dedicated UART RX pad on your FC and configure the corresponding serial port for Serial-based receiver and i-BUS protocol in the firmware settings.

What is the maximum voltage I can supply to this receiver?

The FS-A8S Rev 2 has a wide operating voltage range of 4.0V to 8.4V DC. This allows it to be powered directly from a 1S LiPo (3.7V nominal), a regulated 5V BEC, or a 2S LiPo input (7.4V nominal) without an additional voltage regulator, providing great flexibility in power system design.

How do I mount and position the antenna for best performance?

For optimal signal reception, the 90mm wire antenna should be routed away from carbon fiber parts, battery leads, and video transmitter components. In a typical quadcopter, securing the antenna along a clean plastic or TPU arm, ensuring the last 31mm (the active portion) is straight and unobstructed, will provide the best polarization and range.
