Radiomaster NEXUS Helicopter FBL Flight Controller

Meet the Radiomaster NEXUS Flybarless (FBL) control unit, a marvel of engineering based on the Rotorflight 2.0 reference design. Crafted for peak performance and seamless compatibility, the NEXUS promises an unparalleled Rotorflight experience straight out of the box.

Powered by the advanced STM32F722 MCU and the TDK ICM-42688-P 6-axis MEMS motion tracking device, this flight controller ensures precision with its integrated 3-axis gyroscope and 3-axis accelerometer. With a hefty 128Mb of onboard flash memory, you can log every flight for meticulous fine-tuning and adjustments.

Our Plug'n'Play solder-free RP3-H ExpressLRS receivers come with a locking connector system, guaranteeing a stable connection. Additionally, DSM and S.BUS ports are available for your preferred receiver type, and the multi-function ports are ready for future expansions.

Encased in CNC-machined aluminum, the NEXUS is not just visually stunning but also highly functional, offering protection and heat dissipation for the F722 processor. After extensive R&D and rigorous testing by both developers and experienced helicopter pilots, the NEXUS stands ready to elevate your helicopter flying experience.
