I built the Sig Citabria as my first kit and then built an LT40 to practice flying on. Yes, I definitely did it backwards! The Citabria is much harder to put together than the LT40 but was a blast to build. I found myself getting up at 3 am to sneak downstars to build! If I were to do it all again I would build the LT40, then something like a 4*40 or Somethin' Extra, and then the Citabria. The things I learned building other planes would have helped a bit on the Citabria. I'm looking forward to finally getting that bird in the air in the summer of 2006.
