Kelv,
>I take it you have the flaps hinged to the wing.
Yes
I did indeed use FL3 as the reference in positioning the flap laterally.
Only about 1/4" of flange needed to be cut off the outboard side of the flap
to center FL3 between the dual flap hinge plates. I had no problem lining up
any of the hinge arms. Most lined up with zero flexing. The inboard most
hinge arms may have had a very very slight flex. It was almost perfect. I
cannot remember which side of the w18's the hinge arms bolted up to, but
both wings were symetric at the root. While setting them up, I remembered
that some builders used S-curves. I was happy to see everything line up. I
would probably re-make the flap end, before s-curving the hinge arm (just my
opinion).
As you say, it intuitively appears at least, that they are not considerably
short for sure. Little shorter than your measurement though. Thanks for
those! Still hoping for a few more measurements to compare to..
Regards,
Greg

I take it you have the flaps hinged to the wing.
If your flaps were too short, you would have had problems aligning the flap
hinge arms with the wing hinge plates.
As the tip or outer flap arm FL3 mounts in the centre of the outboard flap
hinge plates W21, any discrepancy in the length of the flap is visible at
the flap root. The flap arm FL1 will be slightly out of line with the wing
root hinge plate W18.
I know some are slightly out, I have looked at many Europas during my build
and have seen the inboard flap hinge arm W19 bolted to both sides of the
inboard wing plate W18. I have also seen some W19 arms with a double bend
to achieve alignment.
If yours were reasonably lined up at the root hinge then the flaps are
likely to be ok in length.
