RE: Twin-Air 45 build thread
OK, now that I know I can post pics, next are the wings. The first step is to edge-glue balsa sheets together and then cut them to size. This plane uses a lot of sheeting and it looks like the engine nacelles are glued directly to the sheeting on the wing. I used the masking tape and white glue method to join them all, then sanded them flat.
The sheeting for the bottom of the wing is joined together on the plans, then the lower spar is glued to the sheeting, and the ribs are glued in place over the top. I was surprised to see that the spars are balsa instead of hardwood. But I guess with all the sheeting hardwood is probably not needed.
A hardwood landing gear support is glued down between two hardwood ribs with a balsa rib located in-between. BTW the instructions tell you to do this AFTER gluing the ribs down (not sure how) but I did it as one assembly. Additional hardwood reinforcment is added to the hardwood ribs, and a hardwood retaining block is added to keep the landing gear from rotating.
The instructions have a picture with an optional hardwood support glued onto the balsa rib, but then the text says that this piece is not included. I am not sure how I will reinforce this assembly yet.
The trailing edge strip is glued on next, and then sheer webs are added at the front edge of the trailing edge sheeting. As you can see in the pics this is as far as I have gotten so far.
