You'll need your continuous rotation servos and some more #10 o-rings (two per hub) to complete this step.
Trim the servo horn down a bit so that it will fit inside the hub.
Make sure it's oriented correctly, and then hot-glue in place.
Screw the hub to the continuous rotation servo and hot-glue the servo into the footie.
Rise. Wash. Repeat for the other foot.
Ready to roll!
