Servos can be modified to make them rotate 360.  I've done it for a 
number of GWS servos.  If the FS3003 uses plastic gears (and I think 
it does) then its pretty easy.  you will have to remove the "nub" 
that prevents rotation and disconnect the feed-back pot. google for 
servo modification - there are numerous pages on this topic.

PWM control of the servo typically is a 1-2 mS pulse within a 10 mS 
window.  A 1.5 mS pulse is neutral (no rotation), a 1.0 mS pulse is 
full speed one direction and 2.0 mS is full the other.  Proportional 
values for proportional speeds (i.e. 1.75 mS is half speed, approx).

PWM to make it rotate. i need some basic info bout it. can i rotate 
it back-and-forth? also, what should i do to make it rotate more than 
360 degree? thanks...
