The RST-135 uses a new type of gear called a strain wave gear. Due to the strong force provided by the strain wave gear and motor, a counterweight is not needed. The mount weights only 3.3kg (7.27lbs), but can carry a payload up to 13.5kg (29.76lbs). Rainbow Astro calls this breakthrough mount a Weightless Mount. The volume and weight of the mount is no longer a problem when travelling for astrophotography.
