High-Performance Gyro with Receiver

The RadioMaster Nexus-XR Rotorflight Helicopter 2.4GHz Receiver Gyro is a high-end, integrated flight controller and receiver system built specifically for RC helicopter pilots seeking precision, simplicity, and reliability.

About the Nexus-XR

Advanced Flight Control Performance

Optimized for Rotorflight 2.2, the Nexus-XR combines a powerful STM32F722 MCU with a high-performance ICM42688P 6-axis gyroscope/accelerometer, delivering exceptionally smooth and accurate flight control. The built-in 256MB flash memory supports extensive flight logging, making it easier to fine-tune performance and diagnose issues. With multiple UART ports and additional PWM outputs, the system is highly adaptable for complex helicopter configurations. Its plug-and-play support for ExpressLRS RP3-H receivers adds convenience, while the CNC-machined aluminum case enhances durability and acts as a heat sink to maintain optimal temperatures during demanding flights.

Integrated ExpressLRS Receiver for Seamless Setup

What sets the Nexus-XR apart is its internal RP4TD-M ExpressLRS 2.4GHz Mini True Diversity Receiver, which offers robust, low-latency signal performance. Utilizing two independent RF paths, it ensures stable, interference-resistant communication with your transmitter. The built-in receiver eliminates the need for additional wiring or mounting space, simplifying installation, especially in compact or streamlined helicopter frames.

Versatile Power & Safety Features

Designed for flexibility, the Nexus-XR supports a wide input voltage range of 5V to 16V, making it compatible with both standard and high-voltage systems. It also supports 12V servos and tail servo/ESC compatibility (760µs/1520µs), expanding its use across various build types. Internally, the system uses isolated power rails to reduce electrical noise and protect sensitive components. For easy configuration access, a USB-C extender is included, and the built-in Rotorflight Rescue function provides an essential emergency recovery feature.
