Ditto on the quality of parts fit, engineering, etc. Definitely study the build and pictures. I ended up using Sig also for the wing sheeting. The glue syringe is a very good way to control the placement and amount of glue. There are a few places in the construction where the expansion can create heartburn. Fortunately I avoided that! I'm quite pleased with the way mine came out. (PassPort wing and modified Spark stab).

The one piece of advice I would have is really post-construction related. Don't let your 18 pound cat walk on the wings...
