Sometimes your way is the better way!

The instructions say to first put the trailing edge on the plan, mark then notch it where the ribs are. Then pin the bottom spar onto the plan and glue on all the ribs. Then sand the ends of the ribs to the same length, glue on the TE, then do the same for the front of the ribs and glue on the leading edge (which isn't notched). This IMO is a recipe for disaster. When I took the left wing off the plan I found that some of the ribs weren't even touching the LE! I had to carefully cut the glue and redo them using thin balsa shims.

Here's how I did the right wing, (after learning that their way doesn't work!)...

First I marked the trailing edge where the ribs were and notched it. Then I did the same for the leading edge and pinned it, the TE and the spar (all three) to the plan and cut, trimmed, sanded and installed each rib individually, so they all fit perfectly in place. The results, need I say are much nicer. The wing went together a lot nicer too.
