Well, KV is one of your most important things to look at when you look for a a motor. KV is simply the x number of rpms per volt. So if your running 6 cells, thats 6x1.2=7.2. 7.2xkv=how many rpms the motors gonna spin. You want to keep it around 35 to 40k so it stays fairly cool and most efficient. There are also other things to look at like the size of it obviously, but you also have to get a ESC to match the amps that the motor can pull. Those were Sensored systems, I would recommend sensorless over sensored anyday. The Novak sensored however are measured by turns and Novak doesn't list the kv anymore.
