Comments: The specified pulse range for this servo is wrong.
I have used hundreds of S03 and any type that I have used has always had the standard 1000us to 2000us pulse range with extended range of about 500us to 2500us.
I have never managed to strip the gears on an S03 and some have been working in robots since 1998.darwin
