hert:
Does anyone have any suggestions on how to release the heat from the servos if the have reached there limit on lift? Do I need resistors?Thanks in advance
Why do you have a fixation on "resistors" to solve every problem?
You have never shown a drawing of your project. If you want to lift a weight and hold it you need an industrial designed servo that is designed to dissipate the heat in the motor. OR you need to design a different moving and holding mechanism.
