and my second question is actually relevant to this forum... where do you get idlers... and any ideas on mounting them?

If you can vary the gear ratio provided in the Kit of Parts by replacing either of the sprockets. To go faster, use a smaller sprocket on your wheel and leave that on the Toughbox output unchanged -- or similarly, use a larger output sprocket on the Toughbox.
Keep in mind when sourcing sprockets that the Toughbox output is a 1/2" diameter, keyed shaft. It's very difficult to find COTS sprockets that have a 1/2" bore and keyway. You may have better luck buying #35 sprockets from
www.andymark.biz or
www.ifirobotics.com, as those contain a bolt pattern that will mate directly with the Kit of Parts wheels.
Idlers can be made in a variety of ways. Search these forums for "idlers" or "chain idlers" or similar and you'll find lots of information.
