Odd that you would think that the Hobbywing system is slower than the Silvercan. It is the equivalent to the Blackcan in performance. If memory seves me correctly, the reason the Australians went to that system was not to run something "slower", but to achieve more uniform motor performance. The Sport Tuned motors were known for the variance in performance from motor. The other reason was to have a motor that was more reliable. Being quite "aged", perhaps Tony or Calvin or some of the other down under racers might enlighten us. I'd hate to rely on my information retention capabilities.

We TCS racers have another problem entirely and that is to find motors motors slow enough to meet the stringent rpm limits that have been imposed. Hate to disagree with you, Jim, but bodies do make a difference. And that is even at the slower speeds we are running. You're right about the Robinson pinion. They also have the advantage of not "stripping" the set screw like the Tamiya flourine coated pinions do and are about half the price.
