No, the usual control range is from a positive-going pulse of about 0.9 to 2 milliseconds length. (The repetition rate is usually in the range of 7 to 20 milliseconds, but that doesn't determine servo or throttle position.) The so-called neutral point is different for different manufacturers and radios. It's usually around 1.2 to 1.5 milliseconds.

That's for old-school equipment, not the latest, proprietary "high-rate" stuff.
