The next step of attaching the wing tips has a mild "pain in the backside" factor. Its really not that hard, its just a small area that has to be sheeted that happens to also have a bit of a curve to it. I started by cutting a piece of the sheeting roughly to size and then wetted it - I had a bottle of windex handy and I sprayed the sheeting with that. I worked it into the wood and coaxed it into the proper shape. Once satisfied with the fit, I CA'd it down onto the wingtip. This is one of those areas that I think CA really has an advantage over wood glues. This is a tough area to clamp, so the instant bonding qualities of the CA makes this much easier. As you can see from Picture1 and Picture2, the sheeting has been applied and is waiting to dry (remember its wet from the windex).

Once the sheeting dried, I took out my handy dandy Dremel. This is a great tool, by the way. I slapped on a cutting disk (remember to wear proper eye protection ) and made quick work of the "overhang" (picture4). I then replaced the cutoff wheel with a sanding drum and sanded the sheeting flush with the wingtip. 5 minutes of work tops ... Of course, I still have the final sanding to do, but it's much easier this way.

While the sheeting was drying, I attached the rear Wingtip Blocks (WTB) and clamped them down.

I looked ahead in the manual to see what I could do while all these pieces cured/dried. The next step was to sand/radius the trailing edge stock in the center of the wing. I started by marking the piece based on the plans (Picture5). Next I turned to my scroll saw to rough cut the piece (picture6). Once the piece was rough cut, I turned to my Dremel again and using the sanding drum I finished the shape (picture7). Again, using these tools greatly reduced my frustration levels - had I needed to do this by hand, it would have taken much much longer - and likely would have been to a lesser quality standard.

The top wing is now almost done. All that's left is to attach the trailing edge, shape the ailerons, and shape the wingtips...
