Holybro Kakute F405-Wing Mini Flight Controller

Shrink the brains of your fixed-wing or VTOL build without dumbing it down. The Holybro Kakute F405-Wing Mini brings full-sized power into a smaller footprint, handling INAV/Ardupilot with ease. Keywords: Kakute F405 Wing Mini, Holybro flight controller, INAV fixed wing FC, Ardupilot ready.

Why You Want It

Your wing deserves more than a leftover quad FC. The F405-Wing Mini was purpose-built: 8 PWM outputs, barometer, SD Blackbox, current sensor input, and plenty of UARTs. It keeps your wiring sane while giving you pro-grade stability in a compact package. Yes, it’s small — no, it won’t make your landings less awful.

Need a GPS, make sure to add the Holybro M10 GPS module
