The NEXUS Flybarless (FBL) control unit has been designed from the ground up based on the Rotorflight 2.0 reference design. All aspects of the NEXUS have been planned and tested for optimum performance and compatibility, ensuring the best out-of-the-box Rotorflight experience on the market today.

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.

RadioMaster 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.

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

Features:

The NEXUS Helicopter flight controller is designed from the ground up specifically for Rotorflight 2.0
Equipped with an advanced STM32F722 MCU and TDK 6-axis MEMS motion tracking device, which combines a 3-axis gyroscope and a 3-axis accelerometer
Built-in Black Box: A large 128MB of onboard flash memory ensures you can log all your flights for fine-tuning and adjustment
Locking connector system compatible with our Plug'n'Play solder-free RP3-H ExpressLRS receivers, You can rest assured that there will be a stable connection between the control unit and the receiver (RP3-H not included)
Features multi-function ports (UART) for future expansion
The NEXUS flight controller is compact and rugged. The CNC case not only protects the internal components but acts as a heat sink to help keep the electronics cool
The NEXUS measures just 41mm x 25mm and is only 13mm high, making it a perfect fit for any size heli build, including 250/450/500/550/600/700 helicopters
The NEXUS flight controller supports a wide range of Tail Motors and Tail ESCs (760μs / 1520μs)
A variety of receivers are supported, including CRSF, ELRS, GHOST, S.BUS, SUMD, IBUS, XBUS, EXBUS, PPM, MSP, DSM2, DSMX, and F PORT
The device has multiple independent power supplies that minimize noise when reaching 1.8V. It includes 1.8V for Gyro, 3.3V for the MCU, and 5.0V for the external interface
Ultra light-weight and flexible USB-C extender cable is included to help in situations where the USB-C port may not be easy to reach. Made as light as possible because every gram counts and uses flexible silicone wires to prevent vibration transfer to the control unit
Rotorflight Rescue function as a standard
