There are slots cut in the top of the panel below the bottom of the windscreen. It's not foolproof for demisting on the ground (but a wiping cloth is!), but it does keep mist cleared in flight. I had one computer fan previously, which worked similarly, but I took it out (heavy, noisy, power consumer).

If anyone can pass on their experience w/ what amount of airflow is sufficient...or insufficient...I'd be grateful I suspect that my local climate in the Pacific NW of the US is similar to conditions in UK. Thanks in advance, Fred A-194 ________________________________ Message 2 _____________________________________ Time: 06:15:12 AM PST US Subject: Europa-List: Re: windscreen de-fogging From: "rampil" David, Thank you very much! Insulating reflective foam. An Excellent suggestion :) Now, if I can just figure out how to keep myself from cooking in the cabin ....

Is this a good way to carry on? This doesnt sound like the europa forum to me. Even if there were facts rather than views it wouldnt be fair. -------- Graeme Bird G-UMPY Mono Classic/XS 912S/Woodcomp 3000/3W Newby: 75 hours 18 months g(at)gdbmk.co.uk Read this topic online here: http://forums.matronics.com/viewtopic.php?p=404070#404070 ________________________________ Message 4 _____________________________________ Time: 12:44:31 PM PST US From: Andrew Sarangan Subject: Europa-List: Fuel tank question After a one year pause, I am getting back into building. I am near the stage of bonding the fuel tank into the CM. I read a lot of discussions about tank swellings and cracking, so I am a bit concerned. Doing a google search, I came across a fuel tank mod document written by Bud Yerly where he suggests using a cork pad in the fuselage to support the tank. The details are a bit unclear to me, so I would like solicit opinions from anyone who can give me some insights. Thanks in advance!! ________________________________ Message 5 _____________________________________ Time: 01:48:35 PM PST US From: Tony Renshaw Subject: Europa-List: Angle of Incidence > Gidday, Spent 15:00 strapped to an aeroplane but thought I should at least say thank you for everyone's input regarding this AOI issue before having a big sleep. I have yet to read all the replies and digest everything but I am miles ahead with the input. Regards Tony Renshaw ________________________________ Message 6 _____________________________________ Time: 02:53:50 PM PST US Subject: Re: Europa-List: Fuel tank question From: andrew cullum Hi Andrew, One question,have you filled your fuel tank with a mix of fuels you are going to use,and contained the tank with a sturdy wooden frame,and left it for at least 6 weeks? The poly-propylene apparently expands by about 10 per cent With the addition of fuel,this was in the old manual,but doesn't appear to be in the new one. Could it be that tanks that have cracked haven't had this pre-soaking? As for the cork at the bottom of the fuselage,sounds like a good idea,I'm sure that Bud can help you out.

The treated tank (forgot which gas exactly) swells less, but now bonds well to epoxies, making the unmodified original way of installing unwise. 2. put in lock-up EPP strips before putting the cradle / tank combination in: http://www.europaowners.org/main.php?g2_itemId=89154 http://www.europaowners.org/main.php?g2_itemId=89398 The idea is: minimize motion. 3. after bonding de cockpit into the canoe fill the space between cradle and canoe with 2-component reasonably heavy polyurethane foam through the fuel outlet access holes (calibrate the action beforehand to avoid the tunnel and the exposed outboard tank surfaces) This makes a port sandwich and a starboard sandwich - my version (Ron Parigoris' rather) of Bud's cork. The idea is: make the stresses still more distributed and the whole installation stronger. Jan de Jong I have been on the verge of putting the top on for a while. ________________________________ Message 9 _____________________________________ Time: 05:37:26 PM PST US Subject: Re: Europa-List: Fuel tank question From: rparigor@suffolk.lib.ny.us Hi Andrew "The details are a bit unclear to me, so I would like solicit opinions from anyone who can give me some insights." Here's my attempt at keeping the fuel inside the tank: http://www.europaowners.org/main.php?g2_itemId=28688 Scuffed tunnel, 3 BID, plastic sheet and injected foam to support.
