I'm kicking off a build of a Sig Mid Star 40. I'll be building this plane for a new friend and I want him to be able to view the process. My first impressions of this kit are very good, everything is packaged in good order. The laser cutting and quality of wood is excellent. The plans come folded, which is a bit of a pain but a few minutes with an iron flattened them out pretty well.

The first order of business is to pin the main spar, rear trailing edge sheeting and rear sub-spar over the plan, we then begin gluing the laser cut "W2" ribs onto the spars and TE sheeting working from the wing tip in. I use a couple triangles to ensure the ribs are 90 degrees in relation to the building board. After all the "W2" ribs are in place, I use the included dihedral gauge to set the proper angle of the root "W1" rib. The remaining two "W1" ribs are then installed.

After all the ribs are glued down, I added the 1/4 inch trailing edge and re-pinned the TE to the board. The top rear TE sheeting is then added
