Just when I thought I had the wings done, I got the wingtips installed with internal antennas and wiring, and realized that Van's had sent the W-1016 R and L ribs mislabelled. (I checked the labels multiple times to make sure they matched the wings. Unfortunately, with the ribs installed, the angled flanges are bending the wrong direction and the wingtip contours do not line up with the ailerons.)

So if anybody is at the stage of mounting wingtips, be sure to double check this. The convex angled flange needs to go on the bottom surface of the wingtip, and the concave angle flange on the top. Not looking forward to drilling out the 38 rivets through fiberglas, dismounting the wingtips and redoing this with replacement parts. Yuk.

Are you sure they were mis-labeled, or were they just put in upside-down?

There are 2 takes to how you can mount them. Some people mount
them flanges facing away from the tip, so they can easily squeeze
the rivets. The Van's plans way (and the way I did them) is to
mount them with the flanges facing into the tips. That gives a
flush, smooth tip-to-aileron fit, with no added gap. No big
problem either way, but it's more asthetic if the flanges are
per-plans. I can see how someone would get turned around
installing the ribs, but if you test fit them per plans before
you drill, and mate them to the wings, it should go OK.
I hope I'm clear in explaining about the flange direction though,
because again, it can be done either way...but that may be
one of the things that turned you around.

Pretty sure they were either mislabelled, or Vans changed the plans, since the set of plans I have show on Page 24-3 a picture (Figure 3) that pretty clearly shows the flanges facing toward the ailerons (ie., the same way the aileron flanges face, so that the two together, as viewed from the rear would look like _[ ]_ (gotta love those ascii graphics)).

Anyway, its all riveted together so it's going to be a set of replacement parts either way.
