RE: What kit did you REALLY enjoy building?
I enjoy every kit I build but the one I got the most enjoyment out of was my Maratuka/Royal Bearcat (believe it or not). It challenged my building skills, made me think about structure and assembly. Did I mention it made me think?
Of the lesser hard builds, I would have to agree with an earlier post and say the Sig Smith Miniplane...that was fun, too.
