@Johnbeere posted:It's going to be necessary to gear up between the motor and worm somehow - if you don't, the locomotive will be incredibly slow. I actually used a worm drive in my Lego B6, with a gear ratio of 4.8:1, it's very slow. The setup you have above is 24:1, about 5 times slower than my B6. Here's a Lego gear ratio calculator, the closer you get to about 1:1 the better: http://gears.sariel.pl/
I didn't realize how slow the lego motors turn. What a pain! I was doing some math today, and gearing up any of the lego motors to go an appreciable speed is going to be challenging. The only thing that works in my favor is the diameter of the drive wheels.
It looks like I will need to change from technic lift arms to technic bricks get enough length. Getting power to at least one axle without the speed loss incurred with a worm gear is going to complicated.
