right --Lasonic TRC-920 said:Sand paper on sand paper super traction!
except ONE problemo --
when motions are allowed to ' slip ' a bit --that acts as a safety clutch -
but if we have solid 100% traction -
than something can break in the stall mode -
ie -- motor or batteries or wires overheat -
or set screws get stripped
or all kinds of shittte can happen
