You mean like something soft? Perhaps a little cardboard and bubblewrap? I have plenty of that hanging around hehehe!Woz wrote: They are a straight swap for the plastic gears.
Remember to break them in before you fit them, the gears are cast and can be as rough as hell.
Also it's a good idea to puck some packking between the bottom of the tank and the first motor and between the two motors. The gear boxes are made out of thin metal and sometimes the top motor can flex out and it'll no longer mesh with the first cog.
