I could buy a 200kv motor and still use 1000W High Power Dc 48V 20.8A supply na dget benefits. I suppose somewhere down the line there is a torque trade-off but thats set aside at the moment.
The general rule of thumb I've always seen is lower the KV the higher the torque. Do you have a size of out runner your looking at? the physical size?
I really think your going to have a hard time finding a outrunner that can do 15k RPM's with no gearbox. You might look into a inrunner style, but your loosing out on the torque advantage.
