I have built numerous Sig Kits and found them to be some of the best available! I do agree with the previous posts that SIG kits are builders kits. The box is full of quality raw materials and a good set of plans. The hardware is always very good and very rarely has to be substituted. I learned to BUILD in the late 60's early 70's and I prefer a kit that I can BUILD and not ASSEMBLE!
You know the kind, one that you actually create sawdust with!!!
One that you actually have to use skills that took time to acquire though practice and determination. A finished product that YOU built because you have mastered the art of model building and know how to create a sound airframe and an aircraft that flys well. Not a step by step jig saw puzzle.
