I finished getting the last of the white plastic covering off of the rear spar. I spent some time going over the plans for the forward wing ribs and was able to locate the pre made gussets that Sonex provided with the kit. I was a little confused about if I needed to make gusset stock pieces -08 and -09 off of section SNX-W15. Later I realized that these were made for section SNX-W16 and were provided also.
