Lastly, 2ms is 180 deg on the servo and full forward on the motor controller. The varying width of the pulse is where the "Modulation" in PWM comes from. By modulating the pulse width, you control the speed of the motor or position of the servo.

So something like this does have to oscilate right? Its not like i send it a 2ms pulse and it just runs full throttle until i tell it otherwise, as soon as i stop giving this 2ms pulse every so often it stops running?
