Right concept, wrong numbers. Servos want to see a pulse about once every

the way in the other. I don't have the exact values here at the office but
those are pretty close and will certainly get the servo to move somewhere in
their proper range. I just bought a Futaba S-138 and it had the pulse widths
printed on the packaging.
