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? Duncan McF. ________________________________ Message 2 _____________________________________ Time: 01:41:02 PM PST US From: "nigel charles" Subject: RE: Europa-List: Noisy Europa 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.

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.

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.

Has anyone used Aerothane paint and if so would you recommend it.
