Overview

The Flywoo O4 Air Unit Cooling CNC Kit is a CNC cooling kit engineered specifically for the O4 series, using a unibody, aviation-grade aluminum design to combine lightweight heat dissipation and structural protection. It supports both 20 x 20mm and 25.5 x 25.5mm mounting configurations for broad FPV drone compatibility.

Key Features

High-efficiency heat dissipation fins: CNC-machined aluminum fins designed for sustained high-load thermal performance
Multi-compatible mounting holes: dual mounting holes (native 25.5mm + extended 20mm)
IPX coaxial cable clamp: reinforced clamping block above O4 coaxial/IPX ports for secure fastening
Weight-optimized design: modular kit adds 6.3g (with O4 lens housing)
Robust material: CNC-machined 6061 alloy enclosure with structural rigidity
Quick disassembly: installation requires only 4 standard screws
Protruding mounting hole design with recessed bottom channels for cable organization (2.2mm clearance)
Embedded lightweight O4 lens housing: imported nylon shell adds 1.3g; lens embedded and fixed with copper nuts on both sides of the shell
