# How to calculate the dependency of speed and weight of a servo? [closed]

Here is a digital servo: Servo

By using the information of details of that thing what is the way to calculate the dependency of the speed of the movement of the car if the load upon the servo is N kg (or gram)? For example I need to know what maximum weight that servo can handle with a maximum speed of M m/s.

If the motor has a constant power, you have the the relatively easy formula $v=P/F$ – Manishearth Mar 30 '12 at 6:15
It would be better if you researched the specs and listed them here first. Without knowing what is constant, we can't answer the question. – Manishearth Mar 30 '12 at 11:25
