Hi ... we are in the r/c car business , many use toothed belts ( usually HTD
type.. strong for their weight ) .. anyway, tensioners are common, and a
couple of flanged ball bearings also common and do the job fine ; For
these bigger apps, consider a spring loaded arm, and stop by your local
hobby shop and check out the small shock absorbers ( coil overs available )
used on dune buggies ... that would stop harmonics from building up,
besides being " real cool" to show your buddies.
