My comment was like George's. A lot of us have been there---a plane on the building board, but our heads spinning on new projects.
Lets face it. When we start, we smack things into terra firma, and 99.9999999% of the time terra firma wins!

So my original comment, is that if you have a Twister on the building bench, finish it! Build it even stock It is a great flyer as designed. Don't worry about the Fancher mod's---yes someone like Ted Fancher can notice the difference, but I
guarantee you won't---at least at this stage.
If you want to fly something right now--hey it is summer already!, it is easiest to "arf". Overall the cheapest and easiest Arf's available are the Brodak Arfs, although I can recommend some other near ARF's (just not marketed that way) like the Ukey and one of Phil's Corehouse planes. A Brodak Super Clown and a LA 25 will go a long way to get you back to flying round and round. As a note, I have the Ukey, the TF Nobler and Flite Streak (needs a LA25 at most), the Brodak Super CLown, the Brodak P40, Sig Primary Force---all have been great flyers for me. If you want to use your ST46, a Brodak Cardinal or Pathfinder can't go wrong---although they may be more than you can handle(realistically) for now.
I love the look of the Sig Chipmunk, but my kit is pretty heavy, so I really would wait a little until you are ready to build and fly it right. In the right hands, the Super Chippy is a pretty good flyer ---at least how I have seen it here in the midwest--(John Paris, Jim Krueger, and some of the Milwaukee guys). I will get around to mine ....some time. It is just too pretty not too!
