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
