About the weight: The whole thing should weigh 12 pounds. The box extrusion on the side is 2x1x.125". We're planning to use this because of our positive experience with it in the past. The stuff is strong, decently light, and shouldn't need replacement. The module rolls on 4 inch custom wheels.

About the reductions, it starts with the stock 14 tooth input gear, and the reductions follow: 14:60;19:60, directly to the center wheel. This gives us a low speed of 7 fps. We're debating adding a ball lock shifter into the tranny, which shouldn't add too much weight or space. However, we'd like to see the game design before we decide if a 2 speed is neccesary.
