I have both systems. The 4300 is not faster than a 27T stock, but has much more torque and corner "launch" in it. A good driver with a 4300 should always be able to beat the same driver with a 27T. Racing at The Den, I was pulling laps off that were .2-.3 sec faster than the next best guy, and my car wasn't set up for the track at all. As much as I'd like to say it was my driving, it wasn't!

Anyway, I'd try running a brushless with you guys anyway, except it doesn't sound like the club wants me any more...
