Description

The FrSky RX8R Pro receiver builds upon the proven RX8R platform with critical upgrades in signal processing and interference resistance. Its enhanced PWM precision and reduced latency provide pilots with tighter, more responsive control inputs, essential for acrobatic FPV flight and precise fixed-wing navigation.

Engineered for reliability, the receiver incorporates robust anti-interference shielding, particularly against ignition noise from gas-powered aircraft, making it suitable for hybrid UAV applications. The integrated redundancy function allows for a secondary receiver to seamlessly take over if the primary signal is lost, ensuring continuous flight control.

Key Features

  • ACCST 2.4GHz protocol ensures stable, long-range communication (>1.5km).
  • Enhanced PWM precision with a deviation of only 0.5µs for accurate servo and flight controller command delivery.
  • Optimized signal path reduces PWM output latency, improving overall system responsiveness.
  • Dedicated redundancy port supports dual-receiver setups for critical failsafe protection.
  • Smart Port telemetry interface transmits real-time flight data (RSSI, voltage, sensor data) to the transmitter.
  • Strong anti-interference design minimizes disruption from electrical noise sources.
  • Firmware upgradeable via the Smart Port for future protocol enhancements and feature updates.
  • Compact and lightweight form factor (46.25mm x 26.6mm, 15g) for easy integration into tight builds.

Applications

  • Primary or redundant receiver for 5-inch and larger FPV racing/freestyle drones requiring reliable SBUS control.
  • Telemetry-enabled receiver for fixed-wing UAVs and RC planes where long-range signal integrity and battery voltage monitoring are critical.
  • Redundancy system component for heavy-lift cinematography drones or industrial inspection platforms.
  • Compatible receiver for FrSky ACCST transmitters (e.g., Taranis, Horus) in complex multirotor or helicopter builds.

Frequently Asked Questions

What is the redundancy function on the FrSky RX8R Pro and how do I set it up?

The redundancy function allows a secondary (slave) RX8R Pro receiver to take over control signal output if the primary (master) receiver loses its link. To set it up, connect both receivers to your flight controller, configure the master receiver normally with telemetry enabled, and set the slave receiver to 'no telemetry' mode via its firmware settings to prevent data bus conflicts.

What is the operating voltage range, and can I power it directly from a 2S LiPo battery?

The RX8R Pro operates from 3.5V to 10V. A fully charged 2S LiPo (8.4V) is within this range, but you must ensure the voltage is clean and stable. It is recommended to power the receiver through a filtered BEC from your ESC or flight controller to avoid noise, especially in high-current FPV drone applications.

How do I update the firmware on the RX8R Pro receiver?

Firmware updates are performed via the Smart Port using a FrSky STK tool or a compatible radio transmitter with a built-in module bay and update cable. You must download the latest ACCST firmware from the official FrSky website and follow their specific flashing procedure to ensure protocol compatibility with your transmitter.

What is the advantage of the reduced PWM latency and precision?

The reduced PWM output latency (9ms less than previous models) and high precision (0.5µs deviation) result in faster and more accurate transmission of control commands from your transmitter to the flight controller. This minimizes perceived control lag, which is critical for acrobatic FPV maneuvers and high-speed racing where immediate response is necessary.
