just read the datasheet of the servo, make sure it uses standard servo PWM, and you should be ok when you modify it.

That would be "Pulse Width Modulation".

K. the pulse cycle of my servo is 20 + 2ms, positive pulse~2ms
size= 40.6*20*38.9 mm
Weight= 39.2g(1.37oz)
It rotates counter-clockwise

yep thats normal


center:
20ms lows
1.5ms highs

one direction:
20ms lows
2.0ms highs

other direction:
20ms lows
1.0 ms highs


this is pulse width modulation
