Description

I am selling my Brand new, never used, still in original packaging, The RadioMaster Nexus X-R Rotor Flight based, 3D RC helicopter flight controller. I have other flight controllers that I use for my personal use and not much into rotorflight, so would like to sell it out to someone who loves Rotor Flight.

The NEXUS -XR revolutionizes based Control System by integrating a cutting-edge ExpressLRS receiver with dual Semtech SX1281 2.4GHz transceivers. This built-in receiver delivers exceptional RF performance, superior range, reliability, and effortless setup. It eliminates the need for external receivers, simplifying installation and reducing weight.

At the core of the Nexus-XR is the powerful STM32F722 MCU, paired with the ICM42688P 6-axis MEMS motion-tracking device. This device provides excellent vibration resistance and enhanced signal rejection, making it ideal for any application.

The Nexus-XR features several key upgrades. An improved BEC delivers more stable power to electronics, enhancing reliability, while the external voltage input now supports a range of 3.6V to 70V. Onboard memory has been expanded to 256MB, allowing for substantially longer data logging. The CNC-machined aluminum case is sleeker yet still serves as a protective shield and heat sink, keeping the system cool even during extended use.

Designed for ultimate convenience, the Nexus-XR’s compact, rugged build fits a wide range of frame sizes, and delivers top performance in demanding conditions.
