Overview
The Holybro Kakute F722 Stack is a versatile, high-performance flight controller and 4in1 ESC combo, designed for FPV pilots who demand smooth control, high current handling, and compatibility with both digital and analog video systems. This stack features the reliable Kakute F722 Flight Controller paired with one of three powerful ESC options:
-
Tekko32 F4 50A ESC (AM32 Firmware)
-
Tekko32 F4 60A ESC (BLHeli32 Firmware)
-
Tekko32 F4 Metal 65A ESC (AM32 Firmware with metal-cased MOSFETs)
With support for up to 8S input, native DJI/Caddx digital VTX integration, high-speed F4 MCUs, and PWM output up to 96kHz, this stack is ideal for freestyle, racing, and long-range quadcopters alike.
