Aveo make some lovely brushed ali eyeball vents
(https://www.aveoengineering.com/lsa-experimental-ul-kits-and-gliders/ > Misc
and Accessories)
which I used in the standard vent extension - I believe the Club has the molds
for these (I made mine while demonstrating composite techniques at the LAA Rally
- the reward was I got to keep the parts I made )
I removed the screw mechanism and superfluous plate, much like Rowland did -
they
can be closed to block all air entering. This photo does not show the stbd
one well, but you might get the idea.
