Holybro Kakute F405 Wing Mini

Holybro Kakute F405‑Wing Mini – Description

The Holybro Kakute F405‑Wing Mini is a compact flight controller specifically designed for fixed-wing aircraft and VTOL drones. Its slim design allows it to fit into tight frames. Equipped with a powerful STM32F405 processor, high-quality IMU, voltage and current sensing, and redundant BEC outputs, it is ideal for autonomous flight using INAV, ArduPilot, or Betaflight.
