Recently I asked how to mod a servo to use as a gear motor. I have since figured this out. With out soldering or taking apart the PC board in the servo casing. I made a 15 Minute video on how to convert a Futaba S3004 servo to work as a drive motor for any of you small robot enthusists.
Ok now you don't need to e-mail me just click the link to see Video.
