Different ESC response for the same input pwm

Hi ,

  I am having a problem setting my ESCs correct for my Quad.Although I calibrate all the ESCs for same pwm response .They do not respond in same fashion.Each motor rotates at different rpm even when i give same pwm to all of them.

 I am using this ESC

 I am clibrating it by keeping pwm high initally then connceting power to motor.I hear init beep then 2 beep i pull down the pwm(throttle).It gets armed and i can use it in that part.

    maybe the bearings on some motors are different/damaged, or the wiring or connectors have more resistance?
