Overview

Dead_K is a lightweight 3" deadcat ultralight quad (~91 g dry weight), designed as a vacation drone: portable, reliable, and optimized for easy filming with a DJI O4 Light — no propellers in the camera view, no fuss.
It’s not meant to be a pure racer, but rather a practical, agile, and fun quad to take anywhere.

Build Philosophy

Dead_K was designed as the perfect travel companion:

Small, light, and crash-resistant.

Enough power for light freestyle.

Comfortable for digital FPV with DJI O4 Light.

Deadcat geometry → no props in the HD feed.

No need to carry a heavy 5" rig or worry about big crashes.
