Not to kill anybodies buzz but when you start to mod it, with the money it costs you can get a better bird. I have two K2's and use E-sky servos and motors, Hobbywing ESC, AR6100 Rx's and Telebee gyros to keep'em cheap.
Rather than dump a lot of money into an E-sky my next bird will be an HDX or Align 450; they come with good frames and high quality aluminum components out of the box. The math just seems to lead me there. MHO
I do agree with you on the math but a lot of people get emotionally attached to a particular heli and spend tons on them... for instance, a $600 blade cx2 I will never understand.
I would like to see the weight savings between the carbon fiber frames and the stock frame because I have a fuselage on my king2 and would like to extend my flight times.
