I put together an online PA-18 drawings viewer. I thought this would be a great and FREE resource for builders and restorers. When reading the drawings I was often frustrated to go find a drawing number on the Northland CD. Also I wanted a better search ability. You still need the Northland CD to get their updated (and excellent) "NL" drawings, but at least you can view all the stock drawings easier now.
Let me know what you think:
Works best with Internet Explorer. It works with Firefox but has some minor strange behavior (flicker). I recommend high speed internet users only. Dial-up will be painful. Also, I have a CD-ROM version that works the same.
