Karl,
not being an aerodynamacist I would still strongly opt for going 'by the
book' here !
I recall having to shave mine to achieve the nrs. For the weight lost I
filled the previously filled holes and things were fine.
If you allow a relative shift f your deflections you'll end up with the
stick being off-center all the time in the lightest case and with a
unpredictable aeroplane in the worst case (if the offsets of both wings
do not happen to coincide).
So, go shaving ! I am sure you had worse jobs 'a do. And I remember that
feeling on fair-weather days that one could be in the air a little
earlier at the price of less attention to detail. But refrain. She will
pay it all back to you.
be well,
Thomas

Subject: Europa-List: Aileron deflections
I am currently rigging my glider wings, hopefully for the last time.
In the workshop I measured the aileron down deflection to be 20
degrees , it is supposed to be 20 down and 23 1/2 up. Now I measure a
maximum of 18 and 16 for down, and about 30 up.
My question is : is it really important to stick to the figures in the
book, or is it the sumtotal of up plus down when making a turn. These
dreaded lead weights are the reason for the down restriction and I would
prefer not having to shave them down.
Any ideas ?

Hi,
I have a metal fuselage cradle that is constructed to the Europa factory design.
I'm going to be doing some proper fuselage work soon and I don't think this
cradle will be sturdy enough. If nothing else it wants modifying to prevent
it damaging the lower moulding.
I've been looking at the 'Chuck Popenhoe knock down' cradle and it seems to be
simple, study and effective and so I think I need to make one of those.
Before I make one, has anyone got one lying around in their workshop that they
don't need anymore? I'm in the Midlands in the UK but can travel to pick it up.
Regards,
Phil

| Subject: | Re: Flap extension |
The "definitive" discussion on flap setting is in the No. 7 Factory
Newsletter, March 1994 (excerpt attached here).
One (or two ) of the taildragger conversions (which use the tri gear
electrically driven means of flap activation) have flap settings up to
(I am told) 40 degrees.
It is reported that 30 to 35 degrees gives a useful increase in drag to
enable steeper approaches.
Collective aerodynamic wisdom suggests that about 30 degrees is the
general limit of any benefit for simple Fowler flaps.
Do any tri gear pilots have a view on the best flap setting for the
shortest possible take off distance? And the optimum setting to take off
AND clear a, say, 50' obstacle (i.e. best compromise for the safest
departure).

It is my recollection that in the early stages of development of the
Europa (when almost any degree of flap could have been designed in) it
was found that anything more than 25degrees increased drag but did not
increase lift. In other words more flap could give you a steeper
approach, but would not reduce the stalling speed.

I get 65 liters total, 7 liters reserve.
It seems there is significant variability here....

Hi Jean-Paul & others
I measured mine last year and I seemed be able to get a little more in after
4 years of "bulging and sagging" of the tank. I came us with 19.1 US Gallons
which is 72 liters in total.

| Subject: | Aileron deflections |
Thomas=2C
You are absolutely right. I was just looking for a quick fix. As it turned
out=2C only one wing was really affected and easily fixed by grinding away
a little from the mass balance boxes=2C plus some pushrod adjustments on bo
th wings.
The glider ailerons are a really close fit in a very narrow closeout. Maybe
it's just me=2C but the clearances on the short wings were much easier to
work with.
best regards=2C Karl
