Time to build the wings for this powered glider. The wingspan of the RB-57F is 122ft 5inches and it is a spectacular sight to see it fly. I remember watching them fly in and out of Kirtland AFB as a kid.. They appear to be hanging in the sky just barely moving along, and the engines were fairly quiet which added to the glider illusion.
At 1:48 it has a 30" wingspan, which makes it the largest papermodel I've ever built. Where will I display it? Not to worry, I'll find someplace.
Each wing is made of 5 large pieces on 2 1/2 pages.
The wingtips were made of a fiberglass or similar material and were fairly light colored in appearance. I've printed the tips on white bond paper and added the de-icer boot, which was only visible on these tips. It was was cut out and treated like a decal. I also added the red/green Navigation lights, green one is just visible in this image.
Cut out tip with pre-glue treatment on edges
After curling leading edge only, glue is applied and clipped at the trailing edge to dry. This wing has a very flat airfoil shape so be careful not to add too much curve towards the trailing edge.
The cutout piece of the starboard mid-section. Notice the small flight control tab that I added on the trailing edge, directly back from the "US" lettering on the wing.

Now, on to attaching to the fuselage.
