Hello IV builders,

Sue and I are having a bit of trouble with our flap tracks. Seems that the 
kit came with 3/16 holes in the aluminum track and larger than 1/4 inch 
holes in the fiberglass track mounting brackets attached to the aft spar. 
The difficulty there is that are NO 2 holes (let alone all three) that align 
in any of the 4 brackets. It looks like the aluminum tracks were drilled 
first and then they guessed at where to go through the glass bracket. When 
the holes didn't line up, they just made them bigger until the bolts would 
go through. If  I install AN3 bolts, I can move the aft end of the track 
more than half an inch!!!

My thoughts are to ask for new undirlled tracks, flox up the existing holes 
in the brackets and through drill new holes in both. This would, of course, 
require complete realignment of the flap tracks but the factory alignment 
was such that the flaps would move only with significant pressure and lots 
of binding anyway.

I really love these "fast build" features. Only takes 3 or 4 times as long 
as doing it yourself from scratch.

Any ideas?
