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 ?
Karl
