3-Inch FPV Drone

The Goal
I wanted to put a high-definition DJI O3 digital system onto a tiny 3-inch drone frame while keeping it under 250g. This required careful placement of components to achieve the best video quality in a tight physical space.
Custom Adapters
The flight controller didn't fit the DJI O3 unit's mounting holes. I 3D-printed custom standoffs to bridge the gap and maintain proper alignment. This also prevents movement and vibration during high-speed flight.
The Result
I built the whole thing in under two hours. It flies well and maintains stable video. Having HD video on a 3-inch drone makes it much easier to navigate compared to analog systems, all while staying in a very small package.
