Steve, do you feel that the 13.5 needs to be geared to its limits to keep up with a stock motor? It's certainly got significantly fewer turns than the 4300 which wasn't -that- far from a stock, especially in top end.
If it does need to be geared aggressively to perform like a stock, do you feel like it will have a shorter life than existing brushless motors, or is there something about this motor that makes it more durable?
Also, do you have any idea when it will be available to the public?
