Speaking as someone who flies the FM2, which I know is technically not on the list, any good BnZ'er can take on the perk farming turn birds as long as he stays fast and has an altitude advantage. The thing is, there are very few good BnZ'ers out there. I'm talking about those like 2cmex who are supernaturally good shots, or RuMaL, who know how to keep pressure on while retaining an e advantage. Some of these planes are so stable you can fly them staring out your rear view, and for me, the typical pony or Dora driver is just an occasional nuisance. My advice: do not take any plane you see for granted. I would not want to face B3Yk in a hurri, Jazzi in an F4F, or surfinn or Candoo in an FM2. These boys fly those birds for a reason and they are very, very good at what they do.
