Gert,

You have a number of push pull rods, depending on where you fix it, the 
backlash,free play, slop, spil,slr (dansk ;-) ) can be in the remaining 
connections btw trailing edge and fixed point, including the aileron 
hinge itself.  If you can put a finger f.ex. on the joint btw aileron 
and pushrod and wiggle the bits youll be able to feel the play if there 
is any.
Continue doing that on all connections until you have eliminated all 
play within reason....

Alex, kit 529-
Wings to be closed, rudder and ribs to fit, engine and instruments to 
buy and fit...paint and upholstery........and then all the little things 
on the wishlist!
(Glider quality finish, magnetic fuel level indication, lots of clever 
and light glass in the panel, an emergency pop out ram air generator and 
a rubber band aileron trim..I will probably have to wait a few years for 
the Stirling engine to be available so the 912S and VP prop is going to 
drive it in the beginning )
