  Well, you really have a mechanical problem - not an electronic one.
  
  A smaller drive gear and a bigger secondary.
  But I think we know it is not really possible to change the gears in a servos case.
  
  You might be able to counter balance what you are doing with a properly placed spring or a pulley and weight system.
  
  If you wanted to go to an electronic solution, you would have to apply more power to the motor [noparse][[/noparse]that means more volts or more amps]. More volts might burn up the motor and you certainly would have to modify the control circuit. More amps would require that you rewind the armiture coils inside the motor.
  
  Easiest thing to do is just buy a better servo motor that can push harder.

  nice solutions...and the best and preferable solution that i'm 'really' afford to do is to make a counter balance...kramer, how i can put the spring to my arm? or pulley mayb?

  Increase the voltage to the servo, but do not go above the maximum rated voltage. Make sure you can supply sufficient current for the servo as well - check the stall current consumption. If you are working the servo that hard, I would use a different servo. Just don't let the magic smoke out - if you do, you won't be able to get it back in, and the servo won't work...

  Kramer, the counter balance does a good job...thank you
