The Budget Robotics servo and wheel sets combine an already-modified R/C servo motor with a rugged rubber, foam, or plastic wheel. The standard-size servo is rated at 56 oz-in (at 6 volts) and uses a Futaba spline hub. The servo has already been modified for continuous rotation (Click here for technical specifications for the servos we use), so there's nothing to disassemble or solder.
We provide the hub and hardware to attach the wheel to the servo. All you do is mount the wheel to the servo using the supplied hardware. (You can use our universal servo brackets for an easy mounting solution).
