REFLECTOR:Air Oil Separator

[Scott Derrick]

Wow, this is an interesting twist on separators.

I knew a guy who made his own separator for a Bonanza that had a sump 
for the collected fluids. He would drain it periodically and said the 
nastiest stuff would come out.

With the nice pusher design of the Velocity I think I would do as others have and just embed the vent in the wing back to the trailing edge outside the prop arc. Everything will stay nice and clean that way and the water gets out too.
