Here is what I wrote to Jerry.
Let me say it was very pleasant to have a group of guys rooting for one in
the face of a great disappointment. Only someone who has built one of these
can understand the feeling of having made a significant mistake and having
to go back and correct it.
Thanks to all.

My attempt to soften Redux, after it had cured a couple weeks, was too a
failure. Too much heat required, verses heat to damage the glass
structure, which conducts heat poorly to get at the green stuff. For my
safety at least, I would be assuming this procedure might give me a
potential airworthiness problem to forever worry me in severe
turbulence.
I'm surprised the factory would advise -- not knowing any builder's
skill level -- removal by any method other than panel destruction and
replacement (requiring essentially $$, that's all!). Otherwise a
Hobson's choice on structural integrity, attempting a fix, the moral
equivalent of "don't force it...use a bigger hammer."
I don't have this style wing, but merely perused the XS manual online.
It's my opinion that the primary purpose of the tapes is such that
improper orientation of the fibers matters only a little, but I have no
credentials to say that. But, when we add two more tapes, we do stiffen
the ass'y there further, concentrating stresses elsewhere. That could
mean a "seven yard gain, with a five yard penalty," as in U.S. football.
So, if the factory can analyze that one with engineering analysis to say
no harm, they should be able to say computationally why -- in stress
paths -- 90 on the tapes is not good. Or more likely just their gut
reaction and "usual rules" for FG construction.
The only thing I would not do was a fix which may compromise the
structure worse than the original problem.

Indeed! We've all got that T-shirt in one form or another, and I sympathise
wholeheartedly with someone like Will who has obviously been unfortunate
enough to have got an XXXXL one. Not a fun repair job, but it sounds like he
attacked it with gusto and I hope his new skins arrive quickly!

| Subject: | Monowheel Tire & Tube life |
--> Europa-List message posted by: "Rmi Guerner" <air.guerner@wanadoo.fr>
Paul,
The max pressure mentioned on my original tyre was 24 PSI. As I was not confident
in the strength of this tyre and wanted to increase that pressure, I replace
it by a Mac Creary Air Trac 8.00-6/6 after 150 hours. I had to keep the
original tube as the valve of the new tube I bought from ACS was incompatible
with the Europa wheel. I inflate now at 30 PSI. The new tire and increased pressure
greatly improves handling on both hard and grass runways. It also increases
slightly the prop clearance. I have now 378 hours. The tyre does not show
any sign of wear.

I am wondering how folks are making out with Monowheel tires and tube life.
If I keep the tube inflation in the 18~20 psi then I find that it is really
tough on the tubes. Yesterday I had my second tube failure while on
landing. If you have ever had this happen is tough going, it is impossible
to move the aircraft by hand.
At this stage I am thinking of changing my tubes every 100 hours, but I am
wondering about the tire. The tire I have now has 370 hours on it and it
still has tread, how ever its obvious that the side walls have been weakened
by the constant running at low pressure, so perhaps I need to change it more
often as well. Thoughts ?

Hi all,
I just got off the telephone from AC Spruce and they tell me that the
7/8-600 inner tube with a right angle valve is no longer available from
McCleary.
Other than order it from Europa and wait, can anyone in the US suggest where
I can purchase one from.
Thanks,
Paul

Paul,
Not sure if this is what you're looking for, but try this link. Picture
is of a tire, but number is for a tube with 90 degree valve...

I am replacing the soft O-200 type Lord mounts with the stiffer ones supplied
by Europa.
Do any of you lister's know the length of the spacers in the FWF kit ?
Thank's, Sam N77EU

Sam,
You are going to have to make up 4 spacers 1.7" long out of .5" tube with an
internal ID of .306" I seem to recall that the standard ones would not
compress the Lord mounts enough when I made mine.
