I have noticed since I started in RC flying last year that I can't seem to throw away anything. Now I know that there are a lot of things I should save. Like the left over balsa sheets after the parts removed. It makes a good place to cut out other pieces that I might need. However, I find myself saving even very small pieces of balsa, thinking that Oh I can find a use for that one some day. Has anyone establised any personal guiedlines or is it save until you can build something?...or simply don't ever let it go.
