FrSky R-XSR 16-Channel Receiver

The FrSky R-XSR 16-Channel Receiver is an ultra-compact and super-lightweight radio receiver designed for FPV drones and racing quadcopters, combining the full functionality of the legendary XSR series in a casing three times smaller. Weighing only 1.5g and measuring 16 x 11 x 5.4 mm, this module is ideal for models with limited frame space, where every gram and millimeter matters.

Compatibility and Purpose

The receiver is compatible with Frsky X-series transmitters in D16 mode and supports telemetry and Smart Port, allowing flight data to be transmitted to the transmitter and ground controllers. Thanks to its switchable SBUS/CPPM output signal, the module easily integrates with both modern flight controllers using SBUS and systems using CPPM.

Advantages and Features

• Ultra-lightweight and compact size — optimal for racing and mini-drones and competitions.
• Telemetry and Smart Port support for real-time monitoring of flight parameters.
• Failsafe mode for safe return or stop in case of connection loss.
• Detachable antennas with IPEX MHF4 connector for easy replacement, orientation adjustment, or space saving in the frame.
• Switchable output signal between SBUS and CPPM for maximum compatibility with various controllers and systems.

Technical Specifications

• Number of channels: 16 when using SBUS (1-8 channels for CPPM)
• Operating voltage: 3~10V
• Current consumption: 70mA at 5V
• Antenna connector: IPEX MHF4
• Dimensions: 16 x 11 x 5.4 mm
• Weight: 1.5 g

Manufacturer: Frsky. Product category: Drones and quadcopters, drone components and spare parts — receivers. The R-XSR model is ideal for pilots looking for a reliable receiver with minimal weight and extensive capabilities: D16 support, telemetry, Smart Port, and SBUS/CPPM compatibility make it a universal solution for various quadcopter configurations/frames. Minimal power consumption and a wide power supply voltage range (3–10V) ensure stable operation with various power sources. Detachable IPEX MHF4 antennas allow the antenna system to be adapted to frame design constraints and improve reception reliability in racing and complex flight conditions.

Practical recommendations: for maximum reliability, install the antenna to avoid shielding from carbon and other metal frame parts, use D16 mode for full telemetry access, and set failsafe parameters according to the aircraft model. The R-XSR is perfectly suited for both competitions and long FPV flights with minimal weight and compactness.
