4.8v vs 6.0v servos!

[RC944]

silly question but why would i want to buy one rather than the other? if im not racing my car do i need to get a 6.0v one and are they better or are they just more powerful?

Most esc's output 6v into the reciver that then runs the servo. If it is a nirto car and you are using 4x AA batteries then you may need a 4.8v servo. Your best off with a 6v though.
