Does anyone have a plant Transfer Function for a Hobby Servo Motor? In other words, does anyone know how to mathematically model a hobby servo motor?

There are examples on how to model a DC motor for use as a Servo motor, but I will like to model my hobby servo motor. The hobby servo motor does contain a DC motor inside the casing but for angular control it works differently. In the hobby servo motor, as the shaft of the DC motor rotates, it turns the gears connected to the horn. The angle made by the horn is the angle we are interested in. Where as in the DC servo motor the angle made by the shaft is the angle we are interested.
Here is the mathematical model for the DC Servo Motor Mathematical Model Derivation for DC servo motor
