Compatible VTX Models:
- For DJI O4 Air Unit Pro–Direct fit.
- For DJI O4 Wide (Modified)–This mount is designed for units upgraded with a 20mm wide lens, CNC aluminum housing, and dual antennas. If you have the stock / original O4 Wide, please select the other listing.
- For DJI O4 (Modified)–This mount is designed for units upgraded with a 20mm wide lens, CNC aluminum housing, and dual antennas. If you have the stock / original O4, please select the other listing.

Feature:
- Easy mounting and quick-release design.
- The fan comes with a protective grill to prevent rocks and branches from hitting the fan and VTX.
- Equipped with a 30mm diameter brushless fan, max speed 14,000 RPM with low power consumption. It covers the VTX effectively and ensures the VTX will not crash even when the RC car is stationary.
Mounting method (choose one option):
- Secure the bottom plate directly onto the body shell with glue / 3M double-sided tape / hot melt adhesive (not included).
- Drill 3 small holes on the RC car shell. Fasten the bottom plate and baffle to the shell using 3 screws, place the baffle inside the RC car shell.

How to Choose the Correct Fan Voltage?
- If connecting to a receiver or flight controller 5V pad, or to a battery output of 5V or lower → Choose the 5V version.
- If connecting directly to a 7.4V–12V battery or a flight controller 9V–12V pad → Choose the 12V version.
- If connecting to a BEC (step-down regulator) with a 5V output → Choose the 5V version.
Tip: Fans operate at peak efficiency under a constant, regulated voltage.
