RotorFlight 2.1

Rotorflight is a cutting-edge flight control software suite designed specifically for single-rotor RC helicopters. Built on the foundation of Betaflight, it expands upon its capabilities with advanced features tailored for helicopter enthusiasts. Rotorflight offers everything RC heli pilots know and love—plus a whole lot more.

With support for additional UARTs and modern protocols, Rotorflight seamlessly integrates with the latest hardware on the market. From GPS and sensors for autopilot, rescue, and position hold, to advanced LoRa control links like ELRS, offering ultra-low latency and impressive range, this software has you covered.

Rotorflight also empowers you to fine-tune your helicopter with precision, thanks to features like vibration filters, blackbox logging on flash chips, and easy radio-based PID tuning. Whether you're looking for robust performance or advanced customization, Rotorflight delivers the ultimate control experience for RC helicopter pilots.

With its advanced STM32F722 MCU and the TDK ICM-42688-P 6-axis MEMS motion tracking device, which combines a 3-axis gyroscope and a 3-axis accelerometer, the NEXUS flight controller ensures precision control and flight. A large 128MB of onboard flash memory ensures you can log all your flights for fine-tuning and adjustment.

The NEXUS features a CNC machined aluminum case as standard, which looks great, protects the control unit, and dissipates heat for the F722 processor. 

The output plugs of NEXUS support a wide range of tail motors/servos/ESC with both 760us and 1520us.

Our Plug'n'Play solder-free RP3-H ExpressLRS receivers feature a locking connector system to ensure a stable connection between the control unit and receiver. DSM and S.BUS ports are also available for use with your selected receiver type. The NEXUS also features multi-function ports for future expansion.

FlyDragon gyro uses the open-source Rotorflight firmware, and has all the great features of the Betaflight platform, as well as the many new features added to the helicopter. One of the great features that Flydragon brings is the integrated ELRS receiver with high quality components & maximum performance!
