I’d recommend their 'beefcake" frame. Thick carbon. Good layout to keep the camera forward of the props. Has room for 2 short stacks. He’s using better carbon on the newer production, too. (I’m sure your owl frame is old production… he’s been out of stock on those for a while). I want to try their lighter frame that is similar to the beefcake, the ‘skydiver’, but they’re out of stock.
Otherwise, I am super happy w/ the komori frame… although it’s a light 2mm carbon one, too.
The ascent x 3" is at least 3mm carbon.
FYI, Komori has a little bit of the props visiable in the video, but not much. The ascent3" has more… (like, 4x3 is prop free, but the rest of the wide 16x9 has props in it, if that makes sense). I keep my camera almost flat, though… If you angle your camera, it the props might drop below the picture.
Flex warranties some of his frames… all the new ones. Not sure about the owl, but you might want to check their website.
Oh shoot, as soon as I hit reply, I remembered you need 30x30 mounting… I don’t know for sure which frames support that.
