Graham thanks - so the idea is more one of the incidence being the same mid-
wing rather than a specific angle?

sorry, I was too brief again, (getting too lazy to type)
The effective angle of attack imho is more dependant on the relationship between
the center of the leading edge radius and the trailing edge than the bit in
between. this can be anything between a flat plate and a thick ellipse and still
have the same angle of attack. Lift is more or less linearly related to AoA
in the cruise. This is when a built in roll will be most irritating. You will
need roll trim, which is useful anyway to account for assymetrical loading.

Eric,
The one I recently replaced (may have stretched a little in 5 =BD years=92 use)
measures:
3/8inch diameter and 21foot long. (10mm x 6.4M)

Roger,
Did you have to remove the engine to replace the Bungee ?

OK I am learning bit by bit.
I think that I was not being clear I meant mid wing span wise not cord wise
but your clarification is useful to say the least.
So the cord is the line/distance between the leading edge and the trailing
edge so that in this instance the angle of incidence is cord 2.5 deg leading
edge up relative to the datum line which is the left windowsill. The
template is merely a method of measuring this - one could for example attach
a straight edge to Leading edge and Trailing edge and achieve the same
effect.
So the next question is roll trim...I am assuming this is a servo embedded
in the aileron connected to a trim tab in the ? right wing.
Anyone have any advice on this type of servo etc?
Will

Hey Will,
I'll be interested in people's response as to right or left wing. Many have
put it on the left so they can have a visual on it. But I think it should be
on the right to that the smooth portion of the trim tab raises up into the
airflow as opposed to the left wing where the linkage side of the trim tab
lowers into the airflow.
As for servo info, mine is an MAC S9 Trim System from Menzimer Aircraft for
about $180. But their website has expired so you might want to check Aircraft
Spruce for their RAC Electric Trim Servos. They look identical. There are
also pix in the Europa Forum from those that have already done it.
Good luck.

Mike,
Thanks - I think (not sure yet) I am planning to get everything together and
flying and then, only if necessary fit a trim.

| Subject: | Oil and Head temps |
--> Europa-List message posted by: "Dean Seitz" <daseitz@cfl.rr.com>
Some advise needed from the 914 guys with XS cowls. Took my third flight
today and my oil temp after leveling out was running at 250 deg F. and head
temp was 220 deg F. The weather is really bad around Florida right now.
Today the temp was about 95 deg and around 100% humidity. Are these temps
normal for this heat and humidity. Anyone running in this kind of weather
that can give me their temps?
Thanks

Hi Will,
This is my approach as well: Wait and see.
I think Tony Krzyzewski has tested a simple string attachment to the
control-stick in order to trim. According to my memories it worked very
well.

Hi Dean,
We have an XS with 912S, so our experience will not be apples-to-apples,
but:
1) On a 100 degF day at about 7,500 foot density altitude (which means
poorer cooling than at sea level), we got about 240 deg F oil temp on
climb out. After we made our cowl mods, this same condition resulted in
220 deg F oil temp. See those 'engine compartment cooling' mods at;
http://terryseaver.home.comcast.net/N135TD_mods.htm
2) Be aware that the standard Rotax oil temp sender location is at the
coolest part of the oil system, right after the oil cooler. We added a
thermocouple at the inlet to the oil tank, and measured temps 50 deg F
higher in climb and 40 deg F higher in cruise, when compared to the
'standard' oil temp.
Regards,
Terry Seaver

The new Evans coolant is supposed to help that problem. Your temps are a
little high but then, it sounds hot down there. When I fly on 90 degree
days, I climb at 100K and that keeps it cooler. I have not yet put in the
Evans stuff but probably will later this summer.

I found that my 914 ran about 15 F. hotter with the Evans coolant.

Nothing beats water for cooling but Lockwood said it was better because it
does not boil in local areas of the heads as water does.

PUT IN THE EVANS COOLANT,HIGHER TEMPS BUT
NO CHANCE OF BOILING. I LIKE IT AND HAVE NOT HAD ANY COOLANT
BOIL OUT SINCE, AND YOUR OIL TEMPS SOUND A BIT HIGH.

Dean, My temps can readily reach 100C (212F) while taxying in hot weatherif
you have to hang about waiting for others to clear, and a climb to 3000' at
full wellycan put both oil & water up nearer 130C (266F). Once in cruise
they settle down to somewhere around 90C. Suggest changing to Centigrade -
sounds less alarming, and besides its progress! Regards, David Joyce, G-XSDJ
