Hello everyone, i'm an electronic newbie.

I want to buy a transmitter and receiver specifically for operating servos. I have a 7.2v battery.

I'm a little confuse about ESC. Do I need ESC for operating just servos motor?

Thanks!

No you do not.

All you need is the battery to operate the receiver and the plugged in servos.

Typically a 4.8 volts or 6.0 volts typically referred to by these voltages.

The battery should have enough capacity to supply the needed current without dropping in voltage below the minimum voltage required by the servos.
That is around 3.8 volts for most servos and 3.4 volts for most receivers.

Some fellows may have different knowledge.

ESC is, in the RC world, the acronym for Electronic Speed Control. An ESC is typically used to control an Electric motor. Typically, an ESC also includes a Battery Eliminator Circuit (BEC), which allows you to use one battery for both the receiver and the electric motor.

If your RC vehicle is powered by an Internal Combustion engine, like one using Methanol, Gasoline, or Jet-A fuel, you will probably not be using an ESC. If you are powering your RC vehicle with an Electric motor, you will probably be using an ESC. If you receiver and servos are drawing more than 5a, you will probably need an external BEC or you can use a separate battery to power the receiver.

Thank you for the lead Busch,

I found it's probably best to use an external BEC.
