Wing, part 1

Before setting out to build this plane I decided to make some changes and adapt it to the 4-channel plane I want. It is going to be equipped with an electric motor rather than a glow-plug 0.049 engine, and I have some modifications planned for the fuselage. The wings will be equipped with ailerons to make it a true 4-channel model. The original kit had an optional add-on aerobatic aileron-wing with a semi-symmetric profile and no dihedral.

The wing I decided to build will have a ~3 degree dihedral and wing-length ailerons. To accommodate the ailerons I made some minor changes to the trailing edge seen in the picture, and printed a rib template from PLA on my 3D printer. The trailing edge spar I used is actually 1/4"x3/8" and not a 1/4"x 3/4" as in the picture.

I cut each rib using the template, which was my first mistake. It takes too long, and if you're not careful to check each one they may not match. A better method would be to "sandwich" rough-cut ribs between two templates and sand all the ribs together.

After a few hours of painstakingly cutting the ribs out of a 1/6" sheet, I dry-fitted the wing parts before gluing them together.
