- Cube 2-4S Brushless FC: BETAFPV brand new Cube series flight controller features a compact AIO layout design, MCU updated from F405 to G473, integrates 2-4S ESC, providing a more powerful power option for Whoop duct drones bulids-making it the ideal propulsion upgrade for Pavo whoops and similar platforms
- Digital-Ready 3IN1 FC: Engineered specifically for digital VTX whoops, the Cube 3IN1 FC consolidates the STM32G473 MCU, 2-4S 30A ESC, and Serial ELRS 2.4GHz RX into a single compact board—streamlining builds while reducing complexity. The STM32G473 MCU running at 168MHz delivers excellent computing capacity for responsive flight performance
- 2-4S Continuous 30A ESC: By integrating 2oz thick copper on the board to enhance thermal efficiency and current handling, the Cube FC features a significantly upgraded 2-4S Bluejay ESC—delivering a robust 30A continuous current, up from 20A in F405 FCs. This ensures reliable power delivery to meet the surge demands of Pavo whoops during aggressive freestyle maneuvers, giving pilots the confidence to push their limits
- Flexible Ports&Customization: Please note that by default, UART3 is connected to the RX and UART4 is connected to the HD VTX. To release UART3, please remove the resistor. Additionally, this FC reserves 2 complete full-featured serial ports that can be used for external CRSF/SBUS receivers, GPS, or other serial devices. You can refer to the product pictures
- User Notice: DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller. For How to flash firmware via Wi-Fi, please email us via Amazon
