You need a steady stream of appropriate pulses to move and to hold a 
position. If you expect rated torque specs, you must meet the pulse rate 
specs as well. The nominal operating range is 1ms to 2ms with 1.5ms the 
center. All servos are not equal. Repeatable centering is a big issue with 
high end RC airplane folks.

Subject: [OT] R/C servos control


> Hi guys
> On the R/C servos when you stop at a certain position do you rely on the

> If it is the later do you guys have any info on it that you could share.
