I am planning to use two HS-5745MG servos, that have been altered for continuous rotation, with 10 cm diameter wheels for a robot I'm building. I am trying to work through the tutorial, but I'm stuck with the rotational speed. The only specs I can find for the servo are:

Dimensions (mm): 29.0 x 59.0 x 52.0

Weight (grams): 161.0

Speed (sec): 0.18

Torque (Kg.cm): 15.00

Ball Raced: Yes

In the end I want to know how fast will my robot travel along the horizontal and what is the max. weight it can be? Any help/pointers much appreciated.
