It's a cool chopper, yeah I' e always liked that sound too, and man it sure does make em!Thanks a lot! My 600 is pretty much in "stock" form with the exception of the upgraded "black" umbrella gears and main gear. Other than that, it's stock motor, stock esc, stock servo's....nothing really "special" about this helicopter but it is definitely a beast and I love it. My wife likes the blade farts so I try to do that as much as I can for her.
