Dave,
I had a similar problem with my XS tri and solved it by countersinking the
arm & substituting countersunk head bolts (with the head towards the spar)
for the normal hex head ones. (procedure and bolts approved and supplied by
Europa). Gives me an extra 3/16th's clearance which seems fine. I used a
spot of Redux under the heads when installing as it is not easy to hold the
c/s bolts to stop them turning when tightening them up.

Subject: Spar vs Ailerons
Hi all,
So I made a great step today. I have drilled and installed the bushings in
my
glider wings and actually was able to install them with the 1/2 inch bolts.
They are sitting at 2.3 and 2.4 degrees dihedral without the bushings being
bonded in for the last time. That is the good news.
The bad news is that with the wings in place and the spars as far forward as
possible, the aileron controls are hitting the spar on the starboard side
and
are unable too move. The bolts that hold the control links are hitting the
spar. I can see one possibility. I have the bolts that hold the rod ends
with
the head toward the tank and the nut toward the spar. I see in the drawing
that is not correct. I was trying to have maximum clearance with the tank.
If
I turn those around, the controls might clear the spar. If that solves it,
there is very little distance between the aileron control arms and the spar.
That brings my question:
