The Mamba MK4 F722 APP + F55 128K BL32 is a powerful stack designed for 5" racing and freestyle drones.
The Mamba MK4 F722 APP flight controller is one of the best Diatone has to offer. It features a STM32F722 processor, reliable MPU6000 gyro, 16MB blackbox memory, barometer, 6 UARTs, I2C port for connecting a magnetometer, 8 motor outputs, TVS diode, and both 5V and 9V BECs. The 9V BEC is switchable and includes a dedicated port for DJI FPV units. The MK4 series stands out with large solder pads for easier builds and repairs. The APP version also includes an integrated Wi-Fi module, allowing wireless configuration using apps like SpeedyBee on your phone—no cables required.
The stack includes the powerful F55 ESC running BlHeli_32 firmware, ensuring smooth and efficient motor operation even at high RPMs. The ESC supports telemetry and has an integrated current sensor. It delivers up to 55A per channel, making it suitable for all standard 2207 motors used in 5" drones. A capacitor is recommended when using a 6S battery. For better heat dissipation, the ESC features an aluminum heatsink, which also protects sensitive components from damage and dirt.
