Hi Mike, I too had one (stbd) bellcrank too close to the spar to allow the
lateral pushrod enough room even after enlarging the rib hole toward the
spar. So I made a plate out of alum and that fixed it. The plate was cut
just a mm or so larger than the footprint of the bellcrank base, drilled
some lightening holes after the stud holes. The thickness I used still left
three threads showing on studs. I called Jim Thursby and he said thats
fine, hes even used just washers on the studs. I have not gotten to fitting
flaps yet
Hang in there, Kevin Klinefelter

I've had a bad day.
I'm finding it increasingly difficult to assemble the wing components
accurately. The bellcrank end of the aileron push rod is far too close to
the spar- I have had to grind off a layer of glass previously added to the
spar in this area. Would I be better off fitting a plate behind the
bellcrank fitting to increase the rod clearance? The factory fitted root end
W18 has only 3/4" showing below the wing instead of the reccommended 1" and
is also fitted away from the inside of the flap closeout. With the flap T/E
lined up with the aileron T/E and the template fitted to the root end I have
about 1/2" clearance outbd flap L/E to closeout and 1/4" at the root end. I
then have an overlap hinge plate to W18 of about 1/2" at the mid and root
hinge points, this despite my correct positioning of the flap hinge arms to
the flap and the other W18's(I've checked) Should I accept this missmatch
and put it down to poor factory tolerences or attempt to close up the flap
L/E to closeout gap to the book figure of 3-5mm and then grind off the T/E
of the aileron to line up with the flap?
Maybe I am expecting too much from this kit. It seems that I have to
guess ahead all the time, trying to anticipate errors and possible fixes -
mostly I'm caught out.
Do I hear grunts and sighs of aggreement out there? Have all you chaps
been through this many times? What else can I expect to meet problemwise
with the wing assembly?
