If I weren't backed up on projects as much as I am, I always wanted to build a Procter Jenny. That looks like a great challenge and done right looks like the real thing. However, between the Laser project, the B-25, P-51, Corsair, SIG Liberty Sport, as well as a few more that are just rolls of paper(hence the laser project) I don't think I would be able to get to it any time soon.
Then again if I win the lotto and can retire, Hire someone to do the house repairs, sell it, find a place with a nice be workshop and spend the rest of my time building and flying.
One can dream, right?
