You should consider what time it takes for a person to build a scratch built aircraft. I started a P.O.S. (Piece of S**t) composite aircraft, it took well over 3000 hours, I was getting pretty close to completion and developed a sensitivity to the Epoxy. Considering I wore glove 99% of the time I was surprised I developed a sensativity. Not only am I sensitive to Epoxy, I am also now sensitive to Latex Gloves. I would never recommend building from scratch, and not if you have a life.
