The XR311 chassis is Tamiya's first offroad chassis. The four wheels all have independent dual a-arms suspended by plastic torsion bars. The motor is mounted in the rear in a closed gearbox where one gear could be swapped for other sizes to acheive different speeds. The big weakness with this chassis is the plastic torsion bars which very often broke.
