The wing fits in the saddle very nicely. I still need to install a couple hardwood blocks in the fuselage and drill the holes through the wing for the rear mounting bolts.

Since the 4*60 wing fits into the 4*60 fuse from the bottom, there is not a tapered trailing edge on the stock wing. Those of you that have built any of the 4* designs will know what I'm talking about. I will need to add some balsa blocks to the trailing edge of the wing and sand them to a taper in order to fill up the rest of the wing saddle in the fuse.

You can see a square hole on the right side of the wing. Since the wing was originally intended fro a 4*60, this hole was cut for aileron extensions. I'll patch it.

I have dremeled a new hole in the bottom of the wing for my extensions.

My friend hates sanding, so he fills with drywall mud and then sands that. Apparently it sands real easy. I HATE the stuff and think more time should be spent with a sanding block and some elbow grease. It doesn't take all that much effort to sand a balsa wing down 99% smooth and then use little tiny bits of filler here and there. I know I'm going to have a hard time getting monokote to stick to this part of the wing. I'll probably try some balsa rite over the drywall mud in hopes that it will make the covering stick easier. I could sand it all off, but there comes a point where you're into the wood and you're just going to weaken the structure trying to get all the drywall mud out of the low spots. Did I mention I hate drywall mud? [:@]

Anyway.........

I am still planning to drill through the trailing edge of this wing for my hold down bolts. The 4*60 wing has hard balsa blocks built inside to accept the bolts. I don't see any reason to add balsa blocks to the back of the wing, sand them to shape, and then drill my hold down bolts through there. Seams like it would be weaker since the 2 center ribs don't go all the way back. Who cares if the bolts are 3" from the tapered trailing edge of the wing? [:-]
