Details

Designed for tight indoor lines, the 1.6-inch ducted frame helps keep flights safer around people and props.

The O4 Pro version pairs HD digital transmission with up to 4K/120fps recording for crisp cinematic whoop footage.

A four-point damping structure helps smooth out vibrations, with added protection around the lens area.

Small enough to pack easily, the compact 85mm class layout is built for small-space flying.

Sub250 1103 14000KV motors with a 12A ESC deliver quick response for controlled indoor moves.

An onboard ELRS 2.4G receiver option keeps the build clean while supporting independent receiver firmware upgrades.

A quick-release battery mount speeds up swaps between packs when practicing indoors or at the park.

The triple quick-release design makes maintenance simpler while improving airflow and heat dissipation around the O4 mount.

Built to handle creative flying in tight environments where larger quads feel risky or cumbersome.

Choose the O4 Pro setup for DJI digital video, or the WTFPV version when you want a lighter build without VTX/camera.

Mint green is the standard look, with a black protective frame included as a bonus gift.

Key specs are listed side-by-side to help match the right version to your receiver and video setup.
