Lego Belt Buggy

You can use the fan motor to drive wheels if you replace the fan with a small pulley. An additional stage of gearing will reduce the speed and increase the power.

Lego and K'Nex are ideal for this. We built the first one using K'Nex and it performed better than the Lego one shown.

Unfortunately, it was dismantled without being photographed.

The pulley was from Craftpacks, although Tech-supplies have them too (sources page).

Great fun, quite instructive and much cheaper than a Lego motor and battery box.
