After eight years of stumbling down and getting up again, hope and
despair, many nights of puzzling and as many of working, lying still for
weeks and taking up the thread again, it is finally so far. PH-LOB (nr.
394) took to the air on Wednesday 25 April 2007 in the capable hands of
it's developer and test-pilot Ivan Shaw.
Ivan's comment on the first line of the journal: "All controls and
stability good. No wing drop. An excellent flying aircraft."
The fun can start now. And I am not just a little proud of that!

| Subject: | Into wind or downwind to run cooler on ground? |
We have. Into wind was better for our Europa with a 3-blade Warp prop. The
reason I mention the prop is that we switched prop and saw considerable
improvement in the cooling.
My theory is that our 3 blade Warp prop was not good at pushing air into the
cowling so pointing it into wind made a big difference. I am not sure how
this theory fits into your scenario?????

Subject: Europa-List: Into wind or downwind to run cooler on ground?
I just read an artilce in April Kitplanes "Baffled by Baffles". One of the
things discovered after tufting everything including the intake for large
displacement aircooled engine was when pointed into the wind, even doing
run up there was absolute no airflow! They descided to not go flying till
they figured out why, and when headed back the second they turned
downwind, air began to flow (They had small camera able to view what was
going on). They began to fool on ground and sure as anything, no flow into
wind, flow begins when downwind. Conclusion was the prop was at more of an
angle of attack pointed downwind and was creating a larger low pressure
area.
Has anyone actual tried pointing downwind, versus pointing into the wind
when stuck on the ground for extended periods with a Europa? Does pointing
downwind yield lower temperatures?
Especial interested in results with monowheel with "Groundloop" adjustable
Airmaster prop (course and fine tested)?
Thx.

My experience with WD is identical to Duncan's. Last year I had a
boil-over (admittedly with the pre-mod coolant pressure cap) whilst
held by ATC for 10 minutes pointing downwind on a taxiway. No
problems now that I make a point of swinging into wind whilst holding.

Some guys here in UK with a Jab 6 tri gear had bad cooling problems with
a Warp Drive 3 blade. Changed to a 2 blade with wider roots close to the
hub and that improved the cooling significantly

Hi,
Thanks for everyone who has replied about tapered and broad blades on 912 and 912S
engines.
Final question, is the blade in this photo tapered or broad? I'm told it's tapered
but it looks broad to me??
Thanks.

Hi All,
Can some one tell me if its normal for the oil pressure to
drop when revving up the engine. After start up the pressure immediately
reaches 4.5 bar, but when I throttle up it drops to 2.5. Is this strange
/ normal ? With all the talk about Rotax not liking oil starvation its
a bit concerning .
Cheers Danny

Regarding Craig Catto's comments re: Rotax hub circle...
After reading Paul Lipps' short article it appears to me that the lack of racking
and twisting and the reduced mass at the tips might go a long way toward minimizing
the loads at the hub which give Craig the fantoids.

Hi Danny,
As I recall, we noticed a similar thing with our 912S, early on. We
noticed that our oil pump inlet 'suction' was too high and suspected
that the 90 deg bend in the molded inlet oil line was collapsing (this
is the line from the oil cooler to the oil pump inlet). We replaced the
bend in the oil line with a short aluminum elbow, which reduced our
suction at the oil pump inlet. As I recall, this also reduced the drop
in oil pressure at higher rpms. The bend I am talking about is the one
just a few inches (maybe 4 inches?) from the oil pump inlet.

Warms up quicker (therefore less cooling airflow) when pointed downwind on
the ground. Also, prop vibration worse.
Sorry to confuse the 'theory'!

If I position my rear seat cushions (factory ones) hard up against
the fuel tank forward face, I end up with a large void in the lumbar
area. Likely to cause severe back ache for those like me 6'2"+
without a large cushion.
Have folk built out the seat back to follow the line given by the
headrest forward face? This would seem more comfortable and also
lower my head by being somewhat more recumbant.

Paul

Paul,
You have it spot on. I have a rolled up blanket/groundsheet at the base of
the seat back. Made a big difference on the comfort front.

Yes that is the thing to do. Follow the headrest angle. Have flown cross
country with this setup without any back pain in Erich Trombley's plane and
have set my plane like this with good results.

Hi! Paul
I used BMW seat backs and the foam does that for me in that I arrange
for the seat back to be raised a little.

Hi Everyone
I just received this from a friend of mine here on the Isle of Man. Anyone
know who the pilot was. Apparently he is a test pilot who owns or flys a
europa trigear?
Alan
Hi,
Unfortunately, I witnessed a plane crash at Andreas (Isle of Man) on Friday
http://www.iomonline.com/news?articleid=2738214
It was me who called on 121.5 - fortunately, the helicopter was 12 minutes
flight time to the south. I just orbited overhead until he was in the
area, and gave final directions to the site (so the bit about the Sea King
witnessing it isn't accurate!)
It was a Skyraider microlight that went down, on the extended centreline
of 06 at Andreas. The wind was reasonably brisk going straight down that
runway, and he crashed just below the top of the Bride Hills. Our theory
is that with two on board they just didn't have sufficient power to make
it over the Bride Hills with the sink on the lee side of the hills. Some
glider club members had seen the aircraft fly before and commented on its
rather poor climb performance.
The pilot was a PFA test pilot, I think his name was Tim and he owns a
Europa (I spoke to him maybe 45 minutes before the crash because we needed
to move his Europa so I could get the Auster out). I think he'd flown
across(from UK) that morning in the Europa. Unfortunately he now has a
broken collar bone and pelvis from what I hear. Ken Wright (one of the
owners, presumably riding in the back seat) I think suffered a broken wrist.
I was very relieved when I circled the site and saw someone exit the
wreckage. From the air,
it looked like the plane had broken into three pieces (fuse, with the
wings separated from the fuselage).
I didn't see the actual impact. He was backtracking when I had entered
downwind, so I orbited while he turned around and took off, and when I saw
him start to climb out I resumed downwind, and landed. I was doing a stop
and go, and on climbout as I got closer to the Bride Hills, I saw the
wreckage.

Hi Paul
As everyone says the seat back needs to follow the line of the headrest.
You need to get your butt as low as possible and as far forward as
practical, depends on the ratio of your torso length to leg length.
You might try a bean bag to find the best possiton, make one up that
fits the seat bottom but only half full of beans so that it is easily
adjustable, then lift yourself out and look at its shape.
Beans are even better than temperfoam btw, they have excellent shock
absorption, much better than springy foam.

| Subject: | Re: oil pressure |
I had the same symptoms, Danny, when my 912S was new. The Rotax oil
pressure gauge also twitched violently, before settling down at about 2.5
bar. However, 350 hours later, it no longer twitches and it runs at about
3.75 bar when hot in the cruise. I can only imagine the pressure relief
valve ball has eventually bedded into its seat. BTW, my previous engine was
a 912 (80 HP) which ran at 4 bar constantly all its life (800 hrs) and the
oil pipes and cooler were exactly the same from one engine to the other, so
I don't believe any of the pipes were collapsing due to suction.
I hope that helps,
William
