FrSky RX8R Pro 2.4G ACCST 8/16CH SBUS Telemetry Receiver

Rx8r Receiver – Product Description

• The FrSky RX8R Pro is an upgraded version of the RX8R receiver, it has all the same features including redundancy. The new ‘Pro’ version has higher precision and lower latency. Its deviation of PWM is reduced to 0.5us, and the delay of PWM output is 9ms less than that of the X8R in high-speed mode. Another feature that is new with the RX8R Pro is the reduction of interference caused by the ignition process.

Features:

• Strong anti-interference performance in the ignition process
• Higher precision of PWM
• Lower latency on the PWM output
• Support redundancy function
• Smart Port enabled and support telemetry data transmission

The Redundancy Function

• For the master and slave receivers, when the master receiver goes into failsafe, the output signal from the slave receiver will be used until the master receiver works again.
• Note: When both the master and slave receivers go into the failsafe, the failsafe signal from the master receiver will be output; The slave receiver should be in no telemetry mode.

Package Includes:

• 1 x FrSky RX8R Pro 2.4G ACCST 8/16CH SBUS Telemetry Receiver
• 1 x User Manual

FrSky RX8R Pro 2.4G ACCST 8/16CH SBUS Telemetry Receiver Overview

The FrSky RX8R Pro is a compact 2.4 GHz ACCST receiver designed for multirotor and fixed-wing applications requiring up to 16 channels via SBUS or 8 channels via PWM. It delivers low-latency control and built-in telemetry over Smart Port, with enhanced anti-interference performance for reliable long-range operation.

Key Features of FrSky RX8R Pro 2.4G ACCST 8/16CH SBUS Telemetry Receiver

• 8 PWM outputs or up to 16 channels via SBUS, with PWM deviation reduced to just 0.5 µs
• 9 ms lower PWM output delay compared to the X8R in high-speed mode for faster response
• Strong anti-interference design to withstand ignition noise and other RF disturbances
• Redundancy function supports master/slave configurations for failsafe switching
• Smart Port enabled for real-time telemetry data transmission to the transmitter
• Fast shipping from Zbotic ensures you get your receiver in 1–2 business days*

Applications and Use Cases

• FPV racing quads demanding ultra-low control latency
• Aerial photography drones needing full-range telemetry feedback
• High-performance fixed-wing models requiring redundancy for safety
• Commercial inspection UAVs operating beyond visual line of sight
• Custom multirotor builds where ignition noise can affect receiver performance
• Educational platforms teaching advanced radio control and telemetry

How to Use FrSky RX8R Pro 2.4G ACCST 8/16CH SBUS Telemetry Receiver

Mount the RX8R Pro in a vibration-damped location, supply 3.5–10 V to its VCC and GND pins, then connect the SBUS output to your flight controller’s SBUS input. Bind to your ACCST-compatible transmitter by entering bind mode (press and hold the F/S button until the LED flashes), then power up the transmitter in bind state. Once bound, connect the Smart Port lead to access telemetry and, if desired, link a slave RX8R Pro for redundancy.

Frequently Asked Questions

How do I bind the RX8R Pro to my FrSky transmitter?

Press and hold the F/S bind button on the RX8R Pro until the LED rapidly flashes, then activate bind mode on your ACCST transmitter. Wait for the LED to turn solid, indicating a successful bind.

What voltage range does the RX8R Pro support?

The receiver accepts an operating voltage from 3.5 V up to 10 V, allowing direct connection to most common LiPo battery outputs or BEC modules.

How does the redundancy function work on the RX8R Pro?

Connect a second RX8R Pro as a slave via the SBUS port and configure one as master. If the master loses signal, the slave automatically takes over, ensuring uninterrupted control.
