Hi all,
I just wrote up a ‘How to Modify a Spring RC SM-S4505B Servo For Continuous Rotation’
The servo that available at GHI store
http://www.ghielectronics.com/catalog/product/160
It’s really easy, took me about less than ten minutes, and nothing to solder or add into!
Hoping that this would be a good tip for someone else that want to build a robot using the Servo instead of Motor.
Here is the link to the Wiki page.

And the video!
