I suppose I forgot to mention that my club, karz.ca, has chosen our replacement for silver cans. We've decdied to go with the new Orca Q Spark ESC and 17.5T combo. The motor is built like a Hobbywing, with a 380 sized rotor in a 540 sized can.

We had them spec'd to 2300kv, so they're dead on with a regular, non-mutant, non-cheatin' silver can. The torque is the hardest thing to get used to. It's instantaneous and the motor pulls hard to it's limit.

The reason we went with 17.5 rather than 13T has to do with our track. Running on a tighter, stickier carpet surface, with a RWD dominant field required that we slow it up a little. If we had a large outdoor track and lots of guys running FWD, the HW 13T would have likely been our top pick. It's a great system and the price is positively unbeatable. (Unless you're shopping for shanzhai!)
