Whilst grateful for the general quietness of the Europa, inside and out,
the cabin NACA vents and associated 'eyeball' contribute substantially
to cabin noise.
If during flight the vent is temporarily blocked with ,say, a finger,
the reduction in overall noise (possibly including some external engine
noise coming through the vent) is noticeable. Same thing can be
experienced on an airliner.
Does anyone have any advice as to how these vents can be quietened?

My overhead eyeball vents are fed from an outward opening flap in the
roof. I have the flap fully open for take-off and landing but have it
only just cracked open in the cruise even on a hot day. The noise level
drops dramatically with it like this so perhaps if you can control the
input flow to the eyeball vents you will control the noise as well as
the flow. High pressure air against a partially open eyeball vent is
likely to be noisier than if the source is controlled before it gets to
the eyeball.

Could you post some pictures of how you constructed this vent and how
you control the opening width?

Here I go into the electric abyss: I am about to start the assembly of
my instrument panel.
I wonder:
How are the wires marked - physically? Any convention for assigning wire
"names" base on purpose?
How about connectors between the panel and airframe? Multiple molex or
something larger combining multiple feeds?
Any use for terminal strips inside the panel?
Pictures are always appreciated.
Thanks

Hi Mike,
I painted my Europa with the Polyfiber/Aerothane system in 2001. 650
flying hours later it is still in good shape. I used the Smooth Prime
water based primer - 3 + 3 coats rolled on as per the book. The
Aerothane topcoat was my first spray job and I used an Axis HVLP gun
http://www.axispro.com/index.php One of these days I might get round to
doing a sanding and buffing job on the paint which would give it that
showroom finish.
Some people seem to have had trouble with the system when they did not
let the primer dry for at least 3 weeks.(see details at
http://www.polyfiber.com/uvsmooth/) If you do use the Aerothane, I
recommend that you obtain the Polyfiber "Flight Gloss" manual -
http://www.aircraftcoverings.co.uk/ias.asp This has a lot of good tips.
Cheers, John
