Subject: | Re: What is the best size and location for Mod 70 access |
panel?
I've spent a lot of time in the back since EFIS CPU was mounted there and to do
Mod 70. What I found was that a cardboard box in the baggage bay the same height
as the bottom of the D opening supported my stomach comfortably and kept
the sharp edge of the opening from cutting. My legs ended up between the headrests.

I think it is because Arplast don't talk good English and Airmaster
don't talk good French. Sad, I did told them both! Airmaster did ask the
question but got no reasonable answer.
I can recommend the Arplast prop but the engineering is not quite as
elegant as the Airmaster and maybe the Woodcomp.
The Arplast fixed pitch prop is also excellent but in the case of the
factory I think "it wasn't invented here" may have something to do with
the decision to stick with Warp.

Subject: | Propeller choice - Whirlwind? |
Dear Europaphiles,
There has been quite a bit of discussion lately regarding choice of
propeller. If you have not bought your prop yet, you may wish to
consider a Whirlwind hydraulic constant speed prop. See
http://www.whirlwindaviation.com/series100.php
I have flown 500 + hours with mine from new and have found it to be
highly reliable and it gives excellent performance. It is also one of
the lightest props available with a weight of 9.3 lbs. I bought it after
hearing Kim Prout at Oshkosh many years ago. Paraphrasing, he said that
it was the most significant single contribution to the performance of
his Europa. I believe that the Series 100 Whirlwind prop was designed
specifically for the Europa and for details of the performance of Kim's
plane, you can see the CAFE report at
http://cafefoundation.org/v2/pdf_apr/Europa%20APR.pdf As you will see,
Kim's Europa Classic with the 80 HP 912 is no slouch. For take-off, I
set the vernier control to max which gives 5,800 rpm and after take-off,
one can easily wind back to 5,500 rpm while remaining at full throttle.
I normally cruise at settings between 5,100 and 5,500 rpm.
To install this prop on a 912/ 912S/914, you must have the gearbox
modification which allows the governor to supply control pressure oil to
the hollow drive shaft. It is preferable to specify this before you take
delivery of the engine. The Czech made Jihostroj governor which is
supplied as part of the package has proved to be completely reliable and
is very accurate. The governor mounts on the engine auxiliary pad which
is normally used for a vacuum pump, so one has to rely on non-vacuum
instruments.
I have no business relationship with Whirlwind. Please contact if you
have any questions.
Cheers, John

John...thank you for putting your oar in. I note the Whirlwind series
100 is 66" diameter...How do you feel about that size?...Are you mono
or trigear?...How do you rate the WW noise level?

Subject: | Re: trailer wing support profile. |
Hi Stevie
Now I have some questions.
The wheel ramp attachment bar, where did it come from? Was it with
the trailer or did you make it.
They are self made. There is one extra advantage with them:
the ramp has quite a tight fit to the monogear and they are difficult
to separate. By using these attachment bars /giant turnbuckles
you can force the ramp move upp AND also down (by chain only upp).
Look at the attachment.
Did the mud guards come with the trailer or did you add them. As you
can see I don't any.
The mud guards come with the trailer with one axle. The other safety
axle
and it=B4s mud guards have added here later.
Because of my accidents "tail wheel drops down when pushing the plane
to the trailer" I will instal this week a floor to the trailer. I
think it prevents
some future damages and also it will prevent shit coming when towing.
Probably one day I have also walls and roof and the trailer is
modified to be
a lorry...
Extra main wheel ramp is also an essential equipment - I will have it
also soon.
I wanna point out I really respect those people who are able to rigg
Europa alone. When only moving wings alone my heart has a rate of
200...
Regards, Raimo

Hi Keith
I did not like those original rubber straps
and removed them. I made new supporters
just like you described them. They are 2" /50 mm
thick wooden blocks (birch plywood board)
and I shaped them by CNC cutter.
They match well to the wing section
and between there are very soft self
adhesive stuf, douple layers.
If you like to get the drawing, please
contact me direct.
Because the pip pins let the supporters
to move a bit, I secure supporters to the
trailer also by extra 13 mm / =BD" bolt & nut.
There are still some movements between
wings and trailer supporters - to prevent any
damages in my first class wing surfaces
I cover the wings by kitchen film before
dropping them to the trailer.
The spars are secured by clamps tightened
by bolts - not only by pip - pins like original
factory trailer. I do not wanna get any damages
to the spars=B4main pip pin holes.
I have also some other modifications like
douple axle for security reasons. Look at the pics.
The riskiest part to operate Europa in my case
has been so far when pushing it to the trailer:
- I have almost destroyed my rudder by hitting it
to the back door of my van=B4s (it was open)
- main wheel gate opened when towing the trailer
(I was lucky Europa did not dropped to the road
because it was fixed by bolts in the tail wheel
and it was not on it=B4s side because I have extra
side supporters). To prevent this situation meet
me again I connected those turnbuckles keeping
gate up together by a strong rubber string with
hooks which prevent them to open spontaneously.
- tail wheel dropped from the rail and transponder
/DME antenna went broken
- tail wheel dropped yesterday again from the rail
and Dynon=B4s OAT sensor went broken and penetrated
through Europas stomach (so I have a similar extra hole
in my Europa=B4s fuselage as Ferg Kyle has his wing=B4s
leading edge!)
Personally I think the only almost safe way to carry
Europa on the roads is to carry it in a big enough lorry
/truck with closed coach. No towing at all. Only flying...

Subject: Europa-List: trailer wing support profile.
Does anyone have a wing profile forward of the spar at the position
of the wing support on the factory trailer? On my drawing this is 2
metres from the root spar pin bush. If anyone has one they could email
or post to me I would be very grateful and it would save a lot of work
trying to transcribe it from the wing. I need it to get the trailer wing
supports made.

Thanks for that information. Whirl Wind is local for me (Ohio), and I
had not realized that their 100-series prop was designed for the
Europa. It looks like the photo on their website is also that of the
Europa. But I am a bit uneasy about modifying the 914's oil system, and
also about losing the auxilary pad (which I had planned for a second
alternator). I spoke to Whirl Wind and they said an electric governor
is a possibility, but I did not press him for details.
