Folks,
Just as an addendum to my previous post, I am looking for ideas on how I can rotate
my wings so the painter can do them in one shot. My current thinking is
to make a hole in the wing tip and put a 12 mm piece of threaded rod as pin.
I would then patch this and repaint the wing tip in a different colour.
Any ideas on what others have done would be very welcome.
Thanks, Paul

Hi! Paul.
Can't remember what my RAF painter did but HE had room to pin and clamp the
two spa's together, set them on THREE tressles in diving mode!(You need
THREE to handle the overturning moment of the dihedral. If they are nicely
clear of the floor he can do the leading edge OK then the trailing edge from
above stood on a beer crate or steps. That way you don't need to turn them
OR touch the tips.

Clamping them together sounds like a neat idea - but a question from the
'newbie': Can the spars support the weight of the wing with the
leading-edge down/up without any damage/problems? If it's acceptable to
do this with the short wings, I assume doing so with the long wings
would be out of the question?
Cheers & thanks,
Pete

Hi! Pete.
I would expect they would carry far more weight and stress in flight pulling
4.8 G be long or short wing, but I'm not the leading authority !

I have several pictures of a jig that supports each wing by the spar only,
made from square steel tube, and provided by another builder - the pictures
and the identity of the other builder (presently in the deep recesses of my
mind and unavailable) are on my office PC. I will forward the pictures and
give proper credit to the designer of the jig later today.

Hi All,
I now have all of my flying surfaces ready for painting(at last!!). The
painter is asking me to have jigs so he can paint them flat. For those who
have gone before could you please share your experiences with me.
As always a picture is worth a thousand words so if you have photographs of
any jigs please send them to me off net.

If the spar can not support the static weight of the wing in any orientation
it would certainly not be strong enough to support the dynamic loading in
flight - I trust that Europa designed a wing that is more than strong enough
to take all loads that any of us will apply to the spars (on the ground or
in flight).

I'm referring to supporting the entire wing with the spar "on it's flat
side" - 90 deg to the normal operating orientation (as the wing was
rotated around for painting). At only 1" thick or so, I was wondering if
there is a problem with concentrated bending moments on the spar at the
face of the first wing rib.
Still curious,

Hi! Pete.
That's why I said CLAMP THEM TOGETHER but suggest some wood spreaders and a
number of clamps.
You normally carry the wings in the spa horizontal mode when rigging anyway
and the spa's are more robust inboard also.

--> Europa-List message posted by: "Richard" <riddon@btinternet.com>
After 1900 hours building over 16 months, G-RIXS finally took to the skies
today.
The weather at Blackpool was absolutely perfect for the first days flight
testing with clear blue sky & light wind.
After the first 20 minute flight, test pilot David Hardaker commented that
the airplane was 'just like a shop bought one' with all t's & p's within
limits, all instruments working well and just a very slight tendency to turn
to port.
After removing the cowling to check the engine which was completely dry with
no apparent fuel, oil or water leaks, a second flight of around 75 minutes
followed when David completed the testing of the radio, transponder,
encoder, stall and Vne. All without problems.
I was invited to take the co-pilot seat for the third flight of around 40
minutes when a 5 minute full power climb was completed and stall
characteristics explored further. With two on board there is a very slight
tendency to turn to starboard.
The only problem encountered was that the stall warner appears to operate in
reverse, sounding continuously at speed above around 55 kts and falling
silent below this speed. Other than this, a completely successful first days
flight testing.
Now I know what that 'Europa Grin' feels like! :-))))

Hi All,
I can't find the wiring diagram for my servo and the MAC site at www.menzimeraircraft.com
does not seem up at the moment.
All I need to know is the two wires that go to the motor as I need to drive the
servo up and down to get the trim tab / rudder clearance correct. If anyone
can tell me the two wires I'd certainly appreciate it.
Thanks, Paul

Re. Stall warner.
I'm wiring and piping mine in today. You've probably fixed the problem
but you've probably connected the sensing tube to the wrong side of
Pressure sensor. I was playing about this afternoon and found the
same!!!
Again Well done.

Europa Monowheel kit 497 is offered for sale.
No reasonable offer refused.
I regret that I am unable to afford the time necessary to build my
Europa. Trying to run a business and other commitments for the foreseeable
future mean that it has taken me 2 years just to complete the stage 1 kit.
At this rate, I will be pushing up daisies long before the plane ever flies.
I really enjoy the build process and all the work to date has been to an
exemplary standard. Mark and Neville at the factory commented that the
glass-work on the stabilators was the best they'd seen.
This really is a project for those with plenty of time and or for the
retired. I plan to purchase another kit in a few years time when I am able
to commit myself to the hours necessary.
The kit is complete minus engine and includes Graeme Singleton tail wheel
kit, speed kit, fuselage and wing kit.
All the glass-work on the stabs, flaps and ailerons completed but not yet
signed off.
Cost 19500 when purchased - any reasonable offer considered.

Hi Alan;
I was in the same boat as you. A new baby, job change, my build partner leaving
the area... all these things conspired to keep my from my dream. Fortunately
I met the owner of Phoenix Composites at last year's Sun 'n Fun fly-in and was
able to enlist their help. I show up at their hanger one long weekend a month
and get supervised help in building. There are other builder assist centers
here in the states as well. The result of all this is I should be flying within
60 days.
The reason I pass this info on is for other potential buyers so they will know
there is plenty of help available to finish the plane if logistics stop you from
completing it the way you first envisioned.
Best of luck to your future. Flying is living... everything else is just waiting

--> Europa-List message posted by: "Ami McFadyean" <ami@mcfadyean.freeserve.co.uk>
I think that this thread is missing the point of the original question.
The bending strength of the spar is proportional to the width of the section
times the third power of the depth of section.
So 6" x 1" edgeways if 36 times stronger than 1" x 6" ( wing in vertical
dive position).
Half of the aircraft weight at a loading of 5g is crudely equivalent to 3430
lbs loading on the wing (excluding self-weight of wing, contribution to lift
from the fuselage and tailplane downforce; before you shoot me down on
this!).
3430 divided by 36 is 95 lbs, about the weight of one complete wing.
So supporting the wings on trestles in the dive position will load the spar
to beyond its designed working limit (but not beyond its ultimate limit).
Bolting the two wings together makes no difference, as the maximum bending
would be at the root rib position on the spar, which is outboard of the
section where the two spars overlap.
I don't think that I would be inclined to support the wing as you suggest,
especially as (whilst in the paint shop) someone is bound to walk in and
lean on the tip-end of the wing (or some other miscellaneous additional
loading beyond mere static self-weight).

| Subject: | Fuel Tubing Choice |
--> Europa-List message posted by: MJKTuck@cs.com
Hi folks,
I am taking the opportunity to change the fuel sight gauge to a new piece of
tubing (polyurethane tubing 0.25 ID) which will run up the passenger side
seat back and found today when I put fuel back in the tank that I had a small
leak which was soaking the cloth covering on the short piece of black rubber
tubing from the tank to the 'tee-piece' and also from the tee to the fuel
drain (again black cotton covered tubing).
I thought it might be the new piece of tube somehow not sealing correctly but
after more investigation determined that the black cotton covered tubing -
which has to be bent through 90 deg - and which had been joggled around a bit
while I was installing the new piece - was cracked and weeping fuel.
I took it off and dissected it and sure enough although the inside looked
smooth, when you bend it, it shows lots of tiny crack/pin holes.
I will have to replace it. I thought I might use the Aircraft Spuce supplied
Polyurethane tubing which they say is unaffected by fuel and has good
abrasion and tear resistance (it's tough stuff to cut and kind of rubbery to
the touch), or should I go for the Bing Alcohol Resistant Fuel Line which
features 'excellent resistance to gasoline, oil, etc.?'.
I couldn't find the black cotton covered type in the Aircraft Spruce book but
I am not overly impressed by it anyway.
Any comments on my choice would be welcomed.
