Axisflying DJI O4 Air Unit CNC Upgrade Kit (20mm)

The Axisflying DJI O4 Air Unit CNC Upgrade Kit provides crucial crash protection and enhanced thermal management for your digital FPV system. Designed to encapsulate the O4 VTX in a rigid enclosure, this upgrade prevents mounting tab breakages and significantly improves heat dissipation during high-power output or stationary bench testing. It seamlessly secures the unit into freestyle or cinematic frames using a standard 20x20mm mounting pattern.

Key features

• Machined aluminium construction for high structural rigidity and impact resistance.

• Acts as an integrated heatsink to manage DJI O4 operating temperatures and prevent thermal throttling.

• Adapts and secures the VTX for standard 20x20mm stack or rear mounting.

• Shields sensitive VTX internals and antenna connectors from direct crash impacts.

Specifications

• Material: CNC Aluminium

• Compatibility: DJI O4 Air Unit

• Mounting pattern: 20x20mm

Ideal for dense freestyle builds or cinewhoops where the Air Unit is exposed to severe impacts or requires extra cooling surface area inside a tight carbon chassis.
