2014 Winter Build = 13 foot Vought SB2U Vindicator
#57
I the bigger designs I use 1/4" Birch ply, smaller one 1/8" Birch ply. With Liteply in between. If the tubes are long there may be alternating Liteply and balsa rig. I figure that if you secure the ends properly then the middle should not take to much strain!

OK, I have the basic wing pretty much done, I put it all together and overall a very nice fit. Personaly, I just dislike wing tubes, but pretty much a necessity on a wing this big. I just need to close up a couple spots on the left top outer panel and center section and sheet the bottom of the right outer panel. Then I will toss the wing aside and start the fuse,so I can fit the wing to the fuse. I will come back later and build the wingtips and flaps and ailerons. Here are a couple of shots of the wing put together:

I see what looks like flanges on the forward part of the rudder, is there a web under there forming a "I" beam? I use the in my designs ans put legs on the webs to facilitate forming a jig for the wing, and H stab.

I have now started the fuselage. I am laying up the right side of the fuse box here. I had to do some thinking on this fuse due to the design and build technique. I strayed from the planes on teh foward potion of the fuse box. Instead of 3/8 square truss structure here, the forward part of the fuse box is made from 3/8 play and I cut in large lightening holes. It saved me just over 2 pounds. This piece makes up the motor box and runs back to Former F-5. I tied the 3/8 square stringers to this piece as well, and made the truss structure from 3/8 square poplar. You can see the gusseting I added. I will let tis epoxy dry overnight and come back tomorrow and start the left side box.
