Servos

We are provided 2 servos in the Kit of Parts.
Does anyone know if there are any restrictions to the amount of additional servos, restricted types of servos?
And also if it would count to the cost of Electronics?

I am just asking since I could not find the servos listed in the Restricted Additional Parts List and the two servos that are given are listed under control systems and not electrical.

Thanks,
Mike
