Hi Michael,
It kind of adds up, your explanation about the aceton and nylon ties, and this
accident. I wonder now, how close the used thinner is to aceton chemically. Are
there any chemical wizards in the audience?
The next edition will not have painted legs just in case!

Surviving a sea ditching.
Looking in the latest issue of the Transair catalogue the Survival
Equipment offered is limited to Lifejackets, ELT's and Liferafts.
IHMO, lifejackets are OK but bearinging mind the survivability in the
North Sea is limited to approximately 20 mins its a bit of a risk to
assume you would be rescued within that time.
Ideally a liferaft would be the best option but weight and bulk are a
consideration in the Europa - not to mention cost.
ELT's - does anyone have any experirnce/ reccomendations of these and
are they legal for use and carriage in the UK?
Additionally I think it would be a good idea to carry a DYE pack and
smoke flares but these dont seem to be readily available in the UK (and
would they be legal to carry - ie: flares or smoke canisters). I suspect
that smoke is probably the most effective way of visually identifying
ones position in the water.
I think many of us assume that in a daylight channel crossing it would
be possible to attract the attention of a passing ship or vessel but
short of ditching in the path of a suitable vessel (which could be
dangerous) the chances of being spotted immediately are probably not
that high.
Any suggestions.

Jos,
Goodness, you frightened me. I was afraid that you had broken one of
your legs!
Glad to hear it was "only" an outrigger leg.
I can not imagine one of those Nylon bars breaking. Nylon is
extremely strong and resistant to breakage. There must have been a
defect in that length of bar. I have a Remington Nylon 66 rifle that
was manufactured back in the mid-'60's and after uncounted rounds of .
22 LR and cleaning solutions the Nylon stock and receiver are just
about like new with no apparent loss of strength.
To go along with Michale Grass's comments... I looked up the
properties of Nylon and the only substances which seem to affect
Nylon are Dilute Acids and Alcohol. I guess Acetone should be added
to that list. It is possible that you or, most probably, the painter
may have exposed the Nylon to one of those?
I'd say you need to contact E'04 for a new pair of legs. I'd replace
both legs, just in case both legs were subjected to the same
situation that caused the breakage. You'd hate to find out that both
legs had been affected on a gusty, cross-wind landing.
Good building and great flying,
Bob Borger

It's been my experience that plain (white) nylon tie-wraps become brittle in
sunlight in short order (2 months in summer), whereas black or similarly
coloured ones will last for years. Tie-wraps are used in amateur radio
antennas. I have some black ones still up 'there' fifteen years
later.........

Those who know
My test pilot has calculated MAC
(mean aerodynamic chord) in my case
(Europa XS Mono w standard wings)
to be 1123 mm (=44,2").
He would like to know its (front points)
distance to the reference point (fuselage datum).
Any idea of that?
He would like to compare MACs position
to the C of G position in per cent, beause it tolds
him aerodynamically more than arms only.
XRTs C of G arm is 1496 mm (=58,9").
Thanks, Raimo

Hi Raimo,
It's on page 6-1 of the owners manual. Section 6, weight and balance.
"Flight C of G limits:
Forward 58" aft of datum,
Aft 62.5 aft of datum,
These limits are equal to 17% -26% mean aerodynamic chord"
The manual is on the factory website, in case you don't have it.

Thanks Jos,
I was careless - there it was.
Outrigger legs: I am sure I cleaned also
them by asetone before nylon primer and
painting. During my taxi tests they have bent
strongly as they should do. I have not noticed
any damages. So far...
You can be sure I am wondering should I also
change them new (thought they last forever)!
Wishes Raimo

| Subject: | EFIS discussion - Blue Mountain |
Dear Europaphiles,
I have just got back from a pleasant week at Sun N Fun and noticed that
there had been a lot of traffic on the list regarding EFIS equipment. I
have comments from two independent sources regarding Blue Mountain
equipment and if anyone is considering purchase of that make, I would be
happy to share my info with them off list.
Cheers, John

Hi All,
I am sitting at the Tampa Airport on my way home from Sun and fun and just
want to respond to a few bits of traffic
from the past few days.
1) the bit on tie wraps in re color is actually incorrect. Sensitivity to
UV and to heat is based on material, not color.
Nylon is the superior material forTyWraps, but the cheap stuff you buy at
the local auto supply store is frequently
not nylon. The test for nylon is to create a sharp (180 degree) bend and
press sides together. If a white line appears in
the material don't waste your money.
2) Re Airventure. Fred, I don't know when you were last there, but I go
every year. I grew up in NYC and live there now, so
I know a million people at a time when I see them. Osh on a good day does
indeed in my in the flesh opinion has a good 200 - 400
thousand people present. SnF this year by comparison will prove to lucky
to have over 50k per day - very light traffic.
3) Speaking of SnF, I took the two day Rotax 912s Maintenance course and
it was most excellent. We spent a fair bit of time under the hood of
CTSWs
Burping oil systems, tearing down Bing 64 carbs, pulling and inspecting
the hydraulic lifters and valves, etc. Broken down a gear box and
re-assembled.
Did carb synchs on a running CTSW, and learning to listen for gear clatter
vs. de-synch. I know there's a bunch of Light Sport guys here and I
really
recommend Dean and his class. It will equip a gear head type or an A&P to
do essentially all line level maint. I took lots of pix and video'd the
hands on stuff.
PS It was interesting to see that the CTSW has only 10 ga wire from that
tiny battery to the master and to the starter. I use #2 welding cable
myself.
At John Wheeler's request I will try to soon put together some useful
Rotax facts from the class, and from Eric from
Kodiak(who of course was not there Officially), Mike from California
Power, Phil and Kerry from Lockwood, and
Shayne (formerly from Lockwood, but still doing deep Rotax work)
.
Some quick points
1) If you use a diet very rich in 100LL (>50%), remove and clean lead from
Oil tank, every oil change. Mogas users should do this at annual
2) The Rotax 9 series really HATES oil starvation
3) Forget about Evans coolant - a waste of time and money
4) Everyone needs to move to the 1.2 bar radiator cap this year (Pascal
from Kodiak just dropped the price during the show
from a ridiculous $74 to a simply high 29.95)
5)Do not let the true CHT (i.e., the internal head coolant temp to exceed
275F). Failure will anneal the head, warping it and causing severe damage
More on True temp measurement and it's approximation later. For now,
just keep Measured CHT below 248F
6) Use the Rotax Maint books and Maint forms in the Line Maint Manual!
7) The Rotax 9 series really HATES oil starvation
