In this
poor video I am was trying to show the slipperential in action. You can hear the motor winding up as the spur spins and the slipperential slips before the tires start to spin.
The pads surface area will have a r/c weight limit where anything but a locked slipper would slip to much. But you don't look real heavy.
For on-road I think it would give more traction tunning ability to match road surfaces. Faster hole shots.
