RADIOMASTER NEXUS Helicopter Flight Controller Rotorflight
INTRODUCTION
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. 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. The Nexus features a CNC machined aluminum case as standard, which looks great, protects the control unit, and dissipates heat for the F722 processor. After more than 12 months of R&D, the Nexus has been tested, tuned, and tested again by not only the developers at Rotorflight but also a team of experienced helicopter pilots who took part in our beta testing program. We would like to thank the Rotorflight team and the Beta testing team for making the Nexus possible!
