Hello Wild and gl with your dream I myself I have a dream plane too, the B-25 Mitchell. I was getting ready to purchase it and realized after reading an article in Backyard Flyer(March 2007)
www.backyardflyer.com that I was no where near ready to attack that project. On page 32 - 36 (Kit Building Basics) it shows you the basics and some great tips. The magazine suggested if you have never built a plane this Miss Stick Jr. was a good plane to get your feet wet. The kit is only $24 and comes with the plans and wood. It looks like for about another $50 -$75 you can do the guts of the plane.

Good luck Wild
