Optional meaning:
- w 5V fan= quick-release mount with 5V fan
- w 12V fan= quick-release mount with 12V fan
- full kit= quick-release mount with 5V fan and power supply module (only compatible with DJI O4 air unit)

Specification:
- Item name: video transmission bracket/gimbal mount/cooling bracket
- Main process: 3D printed
- Material: PETG
- Used for 1/14 scale and larger RC model cars/FPV fixed-wing RC aircraft

Compatibility:
- Compatible with DJI O4 Air Unit
- Compatible with Caddx FPV Ascent Lite/Betafpv P1/ Caddx Walksnail Avatar Mini 1S
Note: when using this mount with the Caddx Ascent Lite, Betafpv P1, or Walksnail Avatar Mini 1S, the stock pigtail antenna may be too short. Please prepare and install your own 5-8 cm antenna to ensure proper clearance and fit.

Specification for mount:
- Camera width: 14mm(0.55inch)
- VTX hole spacing : 25.5x25.5mm(1.00x1.00inch)
- Mount height: 32mm(1.26inch)
- Quick-release plate width: 33mm(1.30inch)
- Remarks: VTX dimension limit: 32x32mm(1.26x1.26inch) max. Overall height (antenna installed): 54mm(2.13inch)

Specification for cooling fan:
- Fan diameter: 30mm(1.18inch)
- Voltage: 5V/12V
- 5V version current: 0.27A
- 12V version current: 0.14A
- The 30mm diameter fan fully covers the VTX area, ensuring the video transmitter keeps running stably without downtime when the RC car is stationary.

Specification for power module(only compatible with DJI O4 air unit):
- Interface type: XT30
- Added transparent heat shrink tubing for effective waterproofing and collision protection.
- Warm tip: to avoid burning out the fan when plugging and unplugging the fan connector, please strictly distinguish the positive and negative poles. Connect the red port wire to the red fan wire, and the black/brown port wire to the black fan wire.

Fixing methods (choose one):
- Attach the bottom plate directly to the car shell with glue, 3M double-sided tape or hot melt glue (consumables not included).
- Drill 3 small holes on the car shell, fasten the bottom plate and baffle to the shell with 3 screws, and place the baffle inside the car shell

How to choose the right fan voltage:
- If connected to the 5V port of receiver or flight controller, or powered by 5V or lower voltage battery, please choose 5V fan.
- If directly connected to 7.4V-12V battery or 9-12V port of flight controller, please choose 12V fan.
- If connected to BEC step-down module with 5V output, please choose 5V fan.
- Tip: The cooling fan achieves maximum efficiency under constant voltage conditions.
