Almost all servos now on the market are three wire types using a
positive and negative (+5volts & Ground) and signal wires.
The servo will respond to a Positive on pulse between .9 and 1.9 msec
in duration. The off time is usually not critical as long as its around
2.5 msec or so. The signal will look something like this:
+5 Volt ___ ___
0 Volt ________| |_______| |_________
I hope this
I hope this diagram shows up all right!
The servo will normally center at about 1.5 msec for Futaba and J.R.
and 1.4 msec for older Kraft radios. (Kraft Sport Series centered at
1.9 msec). How many of you remember Kraft radios?
Hope this helps.
