Overview
The Naked O3 Upgrade Case kit is a 7075 CNC aluminum upgrade kit designed to reduce the size and weight of a DJI O3-based FPV digital transmission setup for micro drones. It supports HD real-time video transmission and 4K video recording with low latency, aiming to improve control feel and increase flight time in indoor or tight spaces.
Key Features
- 7075 CNC upgrade kits and reasonable design to help protect the naked O3 module and prevent unnecessary damage.
- Claw-style camera protection design; save up to 4 g (noted for micro drone builds where every 1 g matters).
- Layered design for enhanced stability and heat dissipation; designed to maximize heat dissipation area and reduce contact issues from collisions.
- Antenna buckle design to help avoid pulling the 5.8G antenna loose during flight or installation.
- Custom O3 Lite filters for enhanced shooting experience; compatible with O3 Lite and O3 Ultra lenses. Options: UV, ND4, ND8, ND16.
