RadioMaster NEXUS Helicopter Flight Controller for Rotorflight

RadioMaster steps into the world of RC Helicopters with their first Helicopter Flight controller: the RadioMaster Nexus Helicopter FBL controller for Rotorflight*.

This helicopter flight controller is based on the Rotorflight 2.0 reference design and designed and tested for over 12 months in close collaboration with the developers at Rotorflight and a team of experienced helicopter pilots.

*Rotorflight is an exciting Open source Helicopter flight controller firmware, based on Betaflight. It offers great performance and great versatility. Read all about it at the official Rotorflight website: https://www.rotorflight.org/ 

Description

Step into the world of OpenSource firmware with the RadioMaster Nexus Flybarless (FBL) control unit for RC helicopters. This flight controller fully runs on the free and OpenSource Rotorflight 2.0 firmware, that is capable of offering awesome performance with high customizability.

Here is a short list of the most important featuers and specifications. Feel free to scroll down to read all details.

MCU, IMU, Barometer and memory
This controller utilizes an STM32F722 MCU and the TDK ICM-42688-P 6-axis MEMS motion tracking device. A SPL06-001 is used as the barometer (altitudemeter) A 128Mb onboard flash memory chip gives you the option to log your flight in detail for fine-tuning and adjustment.

Receiver options
This flight controller for helicopters features extensive options for receivers. A S.BUS, DSM and Serial port are available to connect a receiver of your choice. The following receiver options are available: CRSF, ELRS, GHOST, S.BUS, SUMD, IBUS, XBUS, EXBUS, PPM, MSP, DSM2, DSMX, and F PORT
The best option is to combine the helicopter controller for RotorFlight with the plug and play RadioMaster RP3-H ExpressLRS receiver. No soldering required!

6 UARTS, 4 Servo’s, tail motor or tail esc
6 UARTS are available to add external interfaces. DSM[UART1], S.BUS[UART2], A-CRSF[UART4], PORT-B[UART6], PORT-C[UART3]. 4 Servo ports are available. A Tail ESC/Motor is supported as well as a tail servo configuration. Both 760μs/1520μs Servo are supported

Robust case
A CNC machined aluminum case fully protects the flight controller, looks great and dissipates heat for the strong F722 processor. The case is only 41mm x 25mm x 13mm (L x W x H)

Multiple power supplies to minimize noise
To get the best performance out of the Gyro, MCU and external interfaces, the RadioMaster NEXUS Helicopter Flight Controller for Rotorflight features multiple independent power supplies.
An ultra low noise 1.8V line for the IMU, a 3.3V line for the MCU and a 5.0V line for the external interfaces.

Features

• The RadioMaster 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
