Hey guys, I went to the new england heli crew's show in Mansfeild Mass a couple of weeks ago and the things I saw them do with these coppers was amazing. I would love to see a heli inverted cutting the grass at 10,000 f.p.s., plus a slowed down crash would be great to. The things they do with these helis is unreal. the stress on the blades and rotor head on some of the manuvers would be cool to see if you could film it. THANKS FOR THE GREAT SHOW AND KEEP IT UP!
