| Subject: | windscreen de-fogging |
I took an air feed off the top of one of the side NACA ventilators,
primarily to squirt cool air over the back of the Terra transponder (which
(and the radios too) don't appreciate being cooked behind the standard
sealed Europa panel). 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).

Subject: Europa-List: windscreen de-fogging
Gentlemen,
I'm attempting to select a couple of computer fans to be mounted louvers in
the top of the instrument panel module for the purpose of de-fogging the
windscreen...I'm uncertain as to what cfm ratings or sizes will do the job.
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

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 ....

I can't understand the motivation for these threads, this and the one re G KITS,
unless I am being thick it sounds like someone has wandered up to someone elses
plane seen letters faded etc and proceeded to have a public, in print for
all time, slagging off of it and its state. 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.

| Subject: | 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!!

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

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.
Best Regards
Andy Cullum.

The 120mm brushless dc fan I linked to yesterday was supposed to move 25 CFM
and draw about .4 of an amp
Noise level 25db doesn't say what the weight is, but past experience I would
say it would be around 100g

Andrew,
What I did.
1. make a cradle of 2, locally 3 bid:
http://www.europaowners.org/main.php?g2_itemId=89148
The idea is: good support without local bonding / deformation stresses
Put in the cradle / tank combination as the manual describes for the
bare tank:
http://www.europaowners.org/main.php?g2_itemId=89319
No glues / epoxies on the tank.
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.

I have been on the verge of putting the top on for a while.

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:

Scuffed tunnel, 3 BID, plastic sheet and injected foam to support.
