Newbie - HS-311 Servo 360 Continuous Rotation help

What would happen if I had the servo, instead of playing around with the potentiometer, all I did was cut the "stop" off the gear and put it back together again? That would open it for 360 rotation and I would still of been able to control it via sketches? Right or Wrong??

If you remove the stop, the servo will be 'stopped' by the potentiometer which will probably break. Or perhaps you will strip some gear.
You have not indicated the nature of your application. Perhaps a stepper motor is a better choice. You can also buy gear boxes that extend the range of hobby servos but they tend to be expensive. Check out stepper motors.
