Got the Sig 1/5 Scale Cub kit on Monday and have 1 1/2 wings completed (Today is Thu.). I can't say enough about the quality and engineering in this kit. This is my fourth sig kit and this one is the best yet. Really like the way they use a one-piece notched web (2 per wing). Self-aligns and spaces the ribs.. No more cutting and glueing the individual pieces of web in place...Hope it flys as well as it builds...Fred123[&:]
