Do you need 360 degree rotation with position sensing/control (like a radar dish)? That will be hard to do using hobby/RC servos and motors.
If you need 360 degree rotation for wheels, then you don't want a servo, you want an ESC and a motor that matches. (There are "geared/brushed" motors and ESCs, and there are "brushless" motors and ESCs.)
And, yes, your link didn't work.
A RC transmitter sends some number of channels of control inputs to the receiver.
The receiver receives this control, and turns it into PWM signals, where the pulse width is 1.0 milliseconds for "smallest" and 2.0 milliseconds for "biggest."
An RC servo reads these pulses, and sets its position within its range of motion to match.
An ESC reads these pulses, and sets the speed of the controlled motor to match.
You also need a way to power the receiver and the motors. Typically, this is all tied together to a LiPo battery, although if the voltage needs of different parts are too different, you will also need a UBEC to convert the high voltage to lower voltage for the parts that need it.
