RadioLink R8F 8-Channel Receiver - 2.4GHz, PPM/PWM/S-BUS, Telemetry

The R8F receiver is designed for seamless compatibility with RadioLink's 2.4GHz transmitters, including the RC4GS, RC4GS V2, RC6GS, RC6GS V2, T8FB, and T8S models. Binding is typically done via a simple button press sequence on the receiver and transmitter menu. It uses RadioLink's proprietary protocol and is not compatible with other brands like FrSky, FlySky, or ExpressLRS.

Connect the included voltage feedback cable between your main flight battery's balance lead (or main power leads) and the 'Telemetry' port on the R8F receiver. Once bound, the model's voltage will be transmitted and displayed on your compatible RadioLink transmitter's screen. The system supports monitoring from 1S up to 8S LiPo batteries without requiring an additional telemetry module.

Yes, the R8F is well-suited for drone use. You can connect it to your flight controller (e.g., Betaflight, iNav, ArduPilot) using either the S-BUS or PPM signal output. Configure the corresponding serial RX or PPM input in your flight controller software. The integrated RSSI and voltage telemetry can also be wired to an appropriate FC telemetry pad for in-OSD or telemetry readouts.

Under ideal ground test conditions with clear line of sight, the R8F can achieve a stable control range of up to 800 meters. The actual operational range in flight or in environments with obstacles and RF interference will be less. The 200mm antenna should be positioned clear of carbon fiber and other conductive materials to maximize signal integrity.

The R8F operates on a wide input voltage range of 3V to 15V DC. It can be powered directly from a 5V BEC on your ESC or flight controller, a 3.3V serial pad, or even a 2S LiPo receiver battery. Its low operating current of approximately 30mA makes it efficient for most builds. Ensure your power source is clean and free of excessive noise for optimal performance.
