AFAIK, servo motors won't turn more than 360 degrees.

you can make this turn 360 degrees. ang tawag dito ay servo continous rotaion... kailangan mo lang imod ang servo na available sa market which is usually 180 degrees ang rotation...

sa mod ang kailangan mo lang naman tanggalin ay ang Internal Stop Mechanism ng servo

kung ayaw mo ng mag mod eh di bumili ka ng modified servo sa Parallax... ang E-gizmo may parallax products na, so malamang meron na sila nitong continous rotation servo

The potentiometer also needs to be removed. But this would not be technically a servo motor anymore.  It will just become an "ordinary" DC motor with reduction gears.

Servos need the feed back via the potentiometer for accurate positioning. Removing the potentiometer and the plastic stopper is just using the DC motor, the motor driver and the gears inside.

Bro, nalilito ako    , servo runs on three wires only[which is still valid on mod servos], DC motors reverse rotation through H-Bridges[which mod servo doesnt]..

Even if you remove the internal stop this is still a servo ... and servo mod doesnt mean removing the potentiometer completely...right? you have to connect back the potentiometer...

  No, the potentiometer should be removed because the pot shaft is rotated with the motor. And the pot will not turn full 360.  This is replaced by two resistors of half value of the pot connected.  It is simulating a half-turned potentiometer. 

The H-bridge is internal.  It will work like a normal DC motor after modification.  But the control is still servo-like less than 1.50ms pulse will stop the motor less than that will reverse and more than 1.50 ms will turn forward.  But this does not use the pot feedback so its internal servo circuit is useless.

I think they call it still servo because it is a modified from a servo motor.  But its use is just like a normal DC motor and still utilizing its parts.
