Arduino PWM vs. RC receiver PWM

I am interested in controlling my RC cars via my arduino. I hooked up my arduino to an oscilloscope to view the PWM signal. When I get the scope all dialed in, the scope shows me multiple instances of the same period on the screen. However, when I hook up the the RC receiver to the scope I only see one instance of the period on the screen. Why are they different in this manner?

Nevermind, I figured it out. RC equipment uses PPM not PWM. And the arduino servo library uses PPM, while analogWrite is PWM.

MODs please delete.

Well, no, RC equipment uses a form of PPM, but it is decoded by a 4017 or similar IC into a set of PWM outputs which drive the servos. The servos anticipate a pulse between 1 and 2 ms in width.

It doesn't work that way.
