Thanks for the canopy instructions Don!

OK, back to the build!

After reviewing the plans, it was easy to see that the Banshee wing is not very difficult to build. But not so easy to build it straight. Only 3 ribs have tabs on them, and the 3/16" square T/E is not supported anywhere on the back of the ribs. Also, the dihedral angle is sanded into the root ribs, which leaves a lot of room for error.

I figured that it would be easier to angle the root ribs instead of sanding them, so the first thing to do was to figure out the angle of the root ribs so there would be 7/8" dihedral at each tip. What I did was to prop up the spar at the tip and then tack glue the root rib into place. Next I laid the spar flat on my workbench, and using an angle gauge that I bought at a home improvement store, I measured the angle of the root ribs, which came in at 3 degrees.
