I am not saying do not use 1.0 to 2.0, just stay well in the limits to
be safe on a system like that.
If your travel adjustment is set to 100% on your TX your servo travel is
well within the 1.0 to 2.0, which will give you about +- 45 degrees from
center. If you set your travel adjustment to 150% then you get closer
1.0 and 2.0 (+-90 from center), but never over that. This is so that you
can use any servo with your TX/RX. Of course, I am speaking of a general
R/C system here.
Which brings me to another point. With what's available today in new
technology and the speed we get with Radio telementry systems, why are
we still stuck with the old PPM radio systems?
Two major advantages I can think of is one: you can use same
frequencies, just code your packets. Two: you can have two way
communications (feed back from your model).
