I too have a question about of Mechanum wheels. What is the best gear ratio (GR) to use to prevent your motor controllers from getting too hot? The CIMple Box has a GR of only ~4.8:1. Last year we used the tough box and chains and had a GR of ~13:1. At that GR we had absolutely no problems, but we really think that speed is going to be more important than it was last year. However, we still want the maneuverability of the Mechanums. Any suggestions on a safe GR that will be considerably faster than what we had last year?
