Could you publish some photos of your new oxygen system?

I've had a Catto three blade prop on my RV-8A for three years and the
only bad thing I can say about it is that it makes removing the cowling
a tad more difficult. Otherwise, it has been great - smooth, sexy looking,
and a bit more ground clearance in case of porpoised landings.

Thanks for your note! We do these profiles every so often, so I hope to
be back in touch after a few more flight hours.
Thanks again, and happy flying!
