@Conscripted: K after sending the signal to center, what do u mean adjust the potentiometer? do u mean twist it left and right?
If that is the case, then i guess, when u twist the pot, at a particular angle the servo will stop moving. Is that correct? Well I'm totally confused.
@VegaObscura: Yeah, people told me the HS-425BB was the easiest servo to modify, that's why i got it. I remember to have seen somewhere that the HS-311 is rated 3/10 for difficulty but the HS-425BB is rated just 1/10.
Thnx for ur help guys.
