RADIOMASTER Helicopter Flight Controller CNC Aluminum Case Built-in Black Box for 250 450 500 550 600 700 Helicopters FeaturesThe 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 accelerometerBuilt-in Black Box: A large 128Mb of onboard flash memory ensures you can log all your flights for fine-tuning and adjustmentLocking 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 expansionThe 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 coolThe 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 helicoptersTflight 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 PORTThe 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 interfaceUltra 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 using flexible silicone wires to prevent vibration transfer to the control unit SpecificationItem: Heli Flight Controller Firmware: Rotorflight 2.0MCU: STM32F722RET6Gyro (IMU): ICM-42688-PFlash Memory (Black Box.
