- pulse is 1ms (full left) to 2 ms (full right). 1.5ms pulse is centered.
- pulse rate is typically 50 hz (ie, 50 pulses/sec)
- overpulsing can heat up analog servos
- QUESTION: it seems digital servos don't have to be refreshed. Do analog servos always have to be refreshed? I tried sending a single pulse, and an HX-900 analog servo seemed to hold its position. Perhaps I was doing something wrong?
