Yesterday was "wing" day. . . . I've decided that I like joining the wing panels prior to adding the leading and trailing edges. I believe I can line up the cores more accurately by being able to see the skins than having the leading and trailing edges in the way and any inaccuracy that may have crept in when attaching those pieces. Doxilla brings up a good point, next time I'll measure the shucks as well. The only down side is that now you are having to handle an entire wing instead of wing halves. . . .

The trailing edge on this kit is made up of two "standard size" pieces of balsa which must be custom shaped to match the wing. After thinking about how I was going to shape both of those pieces to fit the wing and also maintain accuracy, I caught sight of my hinge slotter. The hinges did an excellent job of both ensuring the ailerons were centered and held them in place while sanding. In the photos you will see that as usual, I took the long road and sanded between the several pieces of tape, then moved the tape to where I just sanded and repeated. Only at the end of the job did I figure out that I could have just taped the ends of the aileron and saved myself a bunch of hassle.

The wingtips were made out of substantially different densities of wood. . . almost 20 grams difference in weight. If you've ever had a plane that would always roll off to one side when pulling up to a loop, this could be why. That small difference in weight is multiplied by the G-forces of your pull-up - a 20 gram difference on the bench is 80 gram difference in a 4-G pullup. And then you also multiply that by the moment arm of that weight difference all the way out on the wing tip. So. . . out comes the Dremel w/routing attachment. By routing different amounts of wood, I was able to match their weights within 2 grams.

The fixed trailing edge was made of some pretty tough wood also. . . so I thought I may as well attempt to take off a finger tip while saving a couple grams. That's all I could get out of this operation and probably wouldn't do it again. .

Well, at least now it's beginning to look like a wing. . .

I've updated the weights to reflect the joined wing halves. . . still guestimating some of the engine components. . .
