DJI O4 Air Unit (Lite)

My testing (with Goggles 2) shows noticeably increased penetration over the O3, even though this is a single-board, single-antenna design. It's fantastic. Picture quality is amazing as the Mbps seem to "hang on" longer than O3. Plus, it's size makes sticking it into something tiny (like the AtomRC Flying Fish) more than feasible. Onboard recording storage is a little limited, so be prepared to be dumping onboard footage more frequently than you might expect.

Unlocks more possibilities for sub250 DJI builds. Great penetration and range for such a small camera unit. Will purchase again in the future
