Hi!Frans.
I get this problem. The very thin tufnol packing on the quick connect
surfaces unfortunately won't take a double layer. I stripped off the
original material mixed up some very thick redux and left both mating
surfaces quite "proud" of finished thickness(using new tufnol) then fitted
and pinned the wings into place allowing the redux to cure, ten parted it
all to give perfectly flush mating surfaces and tidied up the finished
product. You may still have a slight unwanted gap but I use a layer of self
stick tape which will need replacing every 6 months.
You must however wrap some "cling film" round each mating surface before
pushing the wings in place to ensure any excess redux which squeezes out
doesn't lock both surfaces together preventing the wings being parted. Once
cured and parted it is possible to clean and trim it all up.

Subject: Europa-List: Aileron play
When we built the PH-DIY the aileron system was tight. But after 91
hours of flying and repeated (de)rigging, everything settled in, and
some play developed at the quick connect system.
There is no play within the wing itself, nor in the airplane, but it
sounds like it really is at the mating surface of the two quick connect
surfaces and the surface shows some wear.
Does this sound normal?
With the wing root fairing in place it is a bit awkward to make
measurements and get a visual confirmation.
My plan is to add another tufnol sheet on the bellcrank surface to see
if that solves the problem. (There is no play on the bearings).
Other ideas are welcome of course.
Frans
