Karl,
The roll rate on the MG is a bit disappointing to me as a short wing
flier so I go for the maximum. In the event you need it during a wake
turbulence recovery or near miss, it's imperative to have full
authority.
Most always I build my weights out of foam and glue them on the leading
edge to get the throw I need plus a little for filler and glass. Then I
make the weight arms final.
Only if you build the wing perfectly do the existing weights work. So
far my batting average is 50%.
As for the fix. Die grind the things down to get the down you need.
Reglass over the top.
Now drill a hole in the foam area behind the weight and add more lead.
I mold some round slugs a half inch diameter and just slide them in to a
floxed hole and touch up the hole with flox and filler.
The up limit is most probably the filler on the top of the aileron.
Sand the wing skin back until you get to the point where the build in
stop on the aileron is the limit again.
Doesn't take long. And by now the touchup is a breeze. Just another
day in the shop.

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
