RE: IMAC near Detroit
There are 4-5 guys that fly IMAC at Pontiac (PMAC), most fly Basic or Sportsman, I fly Advanced. I think next year there will be a few more interested in giving IMAC a try, so I'll be working with all of them as well.
As for aircraft I have been flying TBM (Dalton Aviation) 42% Extra 260, in my opinion one of the top two or three IMAC airframes. As for Edge's they can be bit more of a challenge for sequence flying as compared to a Extra or Yak, but if an Edge (generally great for 3D) is what you want, go for it. Currently the Extra 260 and Yak 54 / 55 tend to be considered the top of both worlds, sequence and 3D. You might want to check out AeroWorks new 35% Extra 260 ARF. They are available directly from AeroWorks and Troy Built Models.
