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.

not being an aerodynamacist I would still strongly opt for going 'by the bo
ok' here !
I recall having to shave mine to achieve the nrs. For the weight lost I fil
led the previously filled holes and things were fine.
If you allow a relative shift f your deflections you'll end up with the sti
ck being off-center all the time in the lightest case and with a unpredicta
ble aeroplane in the worst case (if the offsets of both wings do not happen
to coincide).
So=2C 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=2C

Subject: Europa-List: Aileron deflections
I am currently rigging my glider wings=2C hopefully for the last time.
In the workshop I measured the aileron down deflection to be 20 degrees =2C
it is supposed to be 20 down and 23 1/2 up. Now I measure a maximum of 18
and 16 for down=2C and about 30 up.
My question is : is it really important to stick to the figures in the book
=2C 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 no
t having to shave them down.
Any ideas ?
Karl
