Quiet Vent

Some months ago, I read a post from a John Morgan, Minden NV. He was
developing a gadget that was to diminish noise from the clearvision
panel vent. I think he called it the Quiet Vent. Any further word on
his venture? Any contact info? THNX Ron W (RW)

To add a bit to the other posts here, John is an inveterate tinkerer
and was rumored to be close to winning the prize for the Stemme factory
adopting 100 of his suggestions when he sold his Stemme for an ASH26E.
More seriously, I can vouch that John is in this for the fun of helping
others. At $5 or $9 each there's no way money is the motivation.

That said, it might help to describe the QV. It's a piece of flexible
plastic with adhesive on one end that makes a smooth curve on the vent
window, eliminating the turbulence of the sharp edges of the existing
vent. That should reduce noise and John made measurements on his ASH
that showed 10 dB reduction. On my Stemme, I'm not sure it's making
that much difference and I was supposed to do a test for John a few
days ago when I was up at Minden, but we got busy with other things and
the test will have to wait til next trip. John's concerned that the
lack of a good exhaust in the Stemme cockpit (it's pretty air tight)
may cause the QV not to work as well, hence the test.

BTW, all this thread is about QV's and the MK-2 yaw string is being
overlooked. I've had one of those for a while and love it. It replaces
the ugly tape with a small clear plastic diamond (again with adhesive)
and makes a beautiful ship just a little bit prettier.

As you can tell from the above, I'm a good friend of John's so you can
discount my comments as much or as little as you want. But if you talk
to the Stemme and ASH26E owners who have benefited from his many
innovations, you'll be grateful he became a soaring pilot.
