Thought it would be an easy nite. So much for that. In trying to mount the leading edge ribs I found that my attachment scheme to mount the wing-tip was faulty. I then proceeded to tear the whole thing apart and start fresh. This was tricky as I had an entire wing structure balancing on a 2x4 stub while trying to do this.
You can see my final solution in picture 2 below.
I also started the leading edge ribs for the alternate wing, which you see in image 3 below. Altogether I made some good progress, although I can't say this part was fun.
