Although we didn't use mulitple motors or multi-speed, we used the same basic design shown in the pic of pillow blocks, chains/sprockets and a CIM motor for each side. Fairly simple design and no real machining or gear boxes to design. The design was to deliver 13.7 fps and actual was 12.9fps, so we hit about 96% of rated speed.
This year we may build our first gear box and use dual drive motors. I am sure we will not attempt (or need) more than 2 speeds unless we end up with a game in 2005 that really demands it.

I would also recommend the Team 716 2003 single speed as we (and 980) used it this year with much success. It is a little bit more complex than a pillow block, sprocket, and chain setup but it is more efficient, smaller, and lighter. |
