Below is a copy of the reply I sent to Paul with a couple of pictures. I
thought the rest of the forum may be interested.
After much thought, I set up my 24ft x 12ft workshop to paint tailplanes,
flaps, rudder, ailerons, trim tabs & doors which I did all at once.
I made a wooden stand with a single upright & 'T' piece on the top approx 4
ft. long. I then attached the flaps to the ends of the 'T' by the central
hinge arm with a screw through the hole and another under the arm to hold
them in a vertical position, leading edge up so that I could paint both
sides. They were a bit wobbly but quite secure enough to spray.
I extended the upright of the stand and attached the rudder to this by it's
hinges.
The ailerons were the most difficult to support and keep still whilst
spraying. I hung them vertically from the ceiling from one of their hinges,
drive pins uppermost but had to screw a piece of wood between the hinges
then use some wire attached to a screw in the wood, bent to attach to the
drive pins on the ailerons themselves to stop them twisting. Difficult to
describe but if you just hang them up, they spin & twist as you are trying
to spray them so they need to be restrained.
The doors I just hung from the ceiling by the aft hinge and a bolt
temporarily placed in the latch centre.
The tailplanes I supported with a brush handle clamped to a trestle support,
up the torque tube hole.
The trim tabs I simply screwed vertically by their hinges to the doors of my
workshop.
If anyone else would like pictures, please contact me off forum & I will
email.

| Subject: | Having filled wing surfaces |
--> Europa-List message posted by: bizzarro@easynet.co.uk
Hi All
Having filled and sanded our wing surfaces, we thought that they were pretty
good and thus ready for smooth-prime. So smooth-prime we did. However the
smooth-prime and a trusty lead lamp show that things are not as good as we
originally thought. Most of the inconsistencies are easily rectified, however,
it became apparent that there is a dip just in front of and just behind the
spar. It is only small, and cannot be seen in normal lighting conditions. I
would say that the dip is about 0.5mm deep approximately 2cm either side of the
spar.
So the questions are this.
Do we
a) Leave it alone as its effect on the airflow over the wing will be
negligible
Or
b) Fill the dip and sand to blend it into the surrounding surface.
If a, what is the best method? You see, when we were filling this part
before, it was filled high and sanded down until the cloth on the spar could
just be seen under the filler. I guess that what was happening was that the
skin over the foam was flexing in a downward direction whilst being sanded and
the spar wasnt, hence the discrepancy in the curve.
Any ideas that might help us on this issue?
Cheers
Eddie

Eddie,
I would fill it again with Polyfiber, as you can do over the smooth primer, and
than sand it back. When filling it I used a flexible metal trowel about 2 feet
wide to run it down the spar, bent to form the shape of the chamber, to fill the
uneven surface either side of the spar. Once cured I then used belt sand paper
of
differing grit up to 320 mounted on a 3 foot long x 4" wide x 1"thickness piece
of hard wood mounted again on a piece of aluminum with like dimensions (except
1/4"
thickness ) to give it strength and always sanding 45 degrees to the leading edge
not along the spar line, and be gentle as it sands away quickly.
Worked well. Hope it does for you.
Must come and see you again next time in Londontown.
Cheers,
Tim

Eddie;
Fill the dip!!!!! You know its there, and if you paint without filling, every time
the airplane is setting in the sun you will see the dip, and your commit to
yourself will be "darn" I wish I had filled that dip before I painted the
airplane.

Thanks to the 3 Europa that attended the flying at Edds today.
Hope you all had a good flight home.
Interestingly on my way home from the airfield I followed a near complete
Europa tri gear. No eng/wings? on a trailer in the next village .
Must be going to the Hornsea area of East Yorkshire is the builder on the
group?

Hi Tim
G-OWWW is now up and running.
I am off to the US tomorrow (Wed) for 2 weeks returning 13th May.
Anytime you are in London after that, if you would like to see and/or fly in
it you are welcome. As much notice as possible please !
You would go on the Central tube line to Theydon Bois (one stop from the NE
end) and I would pick you up, about 2 miles to the field I fly from.

I noted that too but did not test how much pressure loss results. The
Rotax 914 manual states check valves aren't necessary. The pump mfr
states they are needed where the rather high pressures of which the pump
is capable are required. But Rotax also says they have no liability if
this pump is not used.
This is not to suggest that one cannot find two check valves to be
trusted to not fail in unison, but I am concerned about this: If a
regulator failure, or return line blockage, should occur, there will be
engine problems. The nipple fitting at the front of the pump seems
clearly less secure than at the supplied T-fitting, or at the engine.
Going to full pressure, that one could pop. While attention is focused
on engine malfunction, fuel will be pumped inside the fuselage at a rate
of about a gallon per minute!
In one auto application I know well, an older fuel-injected design of
only 20psi, clamped nipple fittings are not used. In auto recalls, this
is one of them problem areas where they sometimes get it wrong as hoses
age and/or they use lousy hose fittings. I wonder if both Rotax and
Europa could be in error. Maybe Rotax knows the pump leaks back a bit,
the 914 manual is a poor translation, and the overall design is to
prevent potential excess pressure on hose fittings they shouldn't really
be using?
Regards,
Fred F.

Hi All,
I am considering a VP prop on my 914 mono (not flying yet). I know the Airmaster
is very popular but I have been looking at the Arplast PV50 with the constant
speed controller. I thought the broader blades of the Arplast may soak up
the power from the 914 better than the Airmaster.
Any advice greatfully received..

Hi! Ferg/Dave
When at Oshkosh last year I bought a product called "CLEAR VIEW" plastic
cleaner and polish.
The manufacturer claims on the can that as well as cleaning it "helps hide
small scratches by filling them with a fine protective coating. This coating
not only makes them less apparent but improves your view!" Part No.

It is a "Product of:- Aviation Laboratories,Inc. Houston,TX 77092 (800)

Hi! Roger ./Jesper./Kristen.
Yes, been there the last two seasons, it's on the following weekend to
Barkaby (Stockholm), I'm flying out to Barkaby on June 7th but a day later
than originally intended since Ivor has a graduation function to attend.
Then from Monday 9th we intend flying up to Tromso(at least!) on the
Norweigian coast, returning to Stauning on the Friday 13th. The AUSTER CLUB
from Biggin Hill manage to have a "deputation" fly there every year.
Very friendly crowd and worth the trip, after which (Sunday we will be
either returning up the Norway coast and wind/ weather suitable crossing to
Shetland/Orkney and back via Scotland OR back the sensible way.!Still
weather permitting !!!)
I'm copying this on to Jesper Bornaes who with his Dad are two of the main
motivators for the function ,hopefully they will respond to your request for
the web page details.
Regards

--> Europa-List message posted by: "Europa Aircraft" <europa@gate.net>
Hi All,
We have a vario replacing the VSI in our monowheel. As a vario is just a
faster, more responsive VSI, you can use it in place of the standard VSI.
However, you can not compensate it for total energy, as it will no longer be
a VSI. Also, it will not be as useful for instrument flying as it will be
more sensitive that you would like. It will jump around a lot since it does
not have the dampening built in that the typical VSI has.
Happy Building!

===========================================================================
Even though have a Monowheel with short wings, i am sure it will still make
a nice glider.
Granted sink rate higher than is desirable for light thermal, however in a
good long
island convergence soaring is easy, or just gliding should be plenty fun.
Also neat would be to measure sink rate vs speed, precise with windmilling
prop in fine
and course, and stopped prop in fine and course and feather, and also with
flaps. Nice
stuff to know, especial in event of quiet when you don't want quiet.
Later on if aquire glider wings, instrument in place.
Also a bit easier to find and stay in lift if present.
Had a Cessna 170 ragwing for 19 years. Not the greatest glider, had very
small flaps and
was very hard to get prop stopped, but it was great fun. Got over a three
hour flight on
a good Long Island Convergence lift day.
Europa should be far superior with short wings to Cessna.
I never had to use the magic numbers i aquired gliding round with cessna. If
I lost power,
and was over a few thousand feet, would not hesitate to stop prop, which
would require an
abrupt noseup just before stall to get prop to stop. The benefit of a
stopped prop was
evident in a lower sink rate for a given airspeed, hence a better L/D.
I always slowly reduced power on a step down basis to let motor get cool as
possable to
prevent as much thermal shock as i could. Never saw any indication I hurt
motor.
I imagine the 914 with same care would be pretty happy.

I think you'll find that just about every 914 installation on the planet
uses the Rotax supplied pumps without check valves.
Considering that you normally fly the 914 with only one of the pumps
running, if the backflow through the failed/turned off pump was a
problem there wouldn't be any airborne 914 powered aircraft.

I agree with Tony. Check valves are not called for in the manual and I
don't think they are necessary.
I have just finished installing an EI 5L flowmeter and with one pump running
and the return transducer disconnected, the circulating flow was over 75
litres/hour (engine not running) - it would appear any reverse flow through
the inactive pump is negligible.
regards,
Mike.

Jim,
Maybe you did what I am thinking of doing. I'd like to remove all of the
rubber fuel lines in my Europa and replace them with 666 hose. I don't want
to go to the trouble of putting AN style fittings on my tank and fuel
selector, I just want to use the hose clips and barbs that are installed.
Is this what you did?

Hi Eddie,
I have just been down this road and I would encourage you to fill it. I
found that I could apply really thin layers of SuperFil by gently heating it
and applying it with the widest plaster's trowel available. I then worked
it back with 320 grit on a long sanding spline. The SuperFil will go
straight on top of the smooth prime.

.5mm across 2cm is many times the tolerance to preserve low-drag laminar
flow. www.ar-5.com (see Kitplanes article) has more info, but don't buy
the Arnold Tape. I used a dial indicator to find the waviness, as did
Arnold by an even more time-consuming method, and found waviness in
excess of tolerance cannot be felt by hand, nor seen on a glossy painted
one. So, if not desiring to go as far as he did, I'd at least get rid
of the depressions which are that apparent.
Best,
Fred F.

Hi guys,
There is available a VSI that is called an IVSI. It is very
sensitive and reacts right now. They are used in military helicopters
and I used them for years and trained many pilots for instrument flying.
I have one in my Europa and it works great. I'm sure it is cheeper than
a variometer for sail planes. Its a good option for thoes who want to
have it both ways.

Paul,
No, I went to my local auto parts store (NAPA) and got some "fuel
injection" rated fuel lines. Replacing all the rubber hoses from Europa
woth this has proven a good move. The fuels in the States is full of
additives and I wanted something that would stand up to that garbage.
You just pretend you are using europa hose and throw away the europa
supplied stuff. I ran teflon hose with SS braid on the exterior for the
run from my fuel pump forward to the engine. Then used the same for the
return from the engine back to the tank. All the rest is just fuel
injection rated hose.

I am happy with my Airmaster after 106 hours. It will feather and
eventually I expect to have glider wings. The three blades of the Airmaster
seem to "soak up the power". Not sure how the Arplast would be better.

The Tasman variometer goes for $495 - a pretty good devise.
