motors. Fine Mesh Grears. Wait what year is it again? 2085?

pair of gears of a different size in order to gear up or down.

There is one real simple way to eliminate backlash: Use LEGO's 'small-link chain' with their normal gears as sprockets. I paid CAN$7.00 for 135 links from Pitsco-Dacta's Canadian vendor. There is absolutely NO backlash. Mind you, the gearing problem (...) (23 years ago, 5-Apr-01, to lugnet.robotics, lugnet.technic)
