RE: servo voltage?
Servos and receivers are designed to operate on a voltage between 4.5 and 6.5 Volts. Normally, input voltage is around 5 Volts.
How do you get 5 Volts from a 12V battery? The Electronic Speed Control (ESC) has a Battery Eliminator Circuit (BEC) built in that regulates the 12V down to 5V for the receiver and servos. If you connected the 12V battery directly to the receiver, it would burn up.
So, the short answer is, "about 5 Volts to the receiver and servos."
Amps will depend on the size of the servo, the design of the servo, and the load being placed on it by the speed of the plane, the size of the control surface, and the flying style of the pilot.
