Testing out the new O3 Air Unit on a 4" QAV-S quad. This was originally set up with a Vista and Insta360 Go 2 mount. The new O3 Air Unit allows me to remove the Insta360 Go 2 mount while getting better results.

That's cool and a good reason to get the O3. Might even get a 3 inch below 250g if you can skip the (naked) action cam.

Very nice to see!

Excellent test of the O3 Air Unit.    Exhilarating footage.
