Also, just because a motor pulls more amps, does not mean it has more torque either. There are a lot of factors your not taking into account.

Actually that is my point. kv DOES determine kt. Kt is the torque per amp pulled, not just the torque. If two motors each pull x amps on y volts they will both have the same power if they have the same efficiency. That means kt multiplied by kv is a constant, ONE number for all brushless motors, because ultimately power = rpm x torque. So yes, for every kv value there is a kt value to get that number. The only thing that changes btw when a motor is inefficient is rpm. A motor that is 50% efficient at x amps and y volts will have 1/2 rpm as it does unloaded. Torque is uneffected by efficiency. If you disagree, I'd like to know your reasoning before you just tell me im wrong.
