2. RadioMaster Nexus-XR Helicopter Flight Controller Integrated 2.4GHz ExpressLRS Receiver - Red

The Nexus-XR revolutionizes helicopter flight controllers 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 electric and nitro helicopters.

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. Memory has been upgraded to 256MB, enabling longer flight logs. The CNC-machined aluminum case is sleeker yet still serves as a protective shield and heat sink, keeping the system cool during intense flights.

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