I'm not 100% sure, but I think the Slate motors are either 2 or 2.5T. It's really hard to compare a standard 2 pole motor to one of our motors because the design of the motor is vastly different. Our green motors are mostly 1T motors with various lengths of stator to change the KV. If everything else was equal, going to a 4 pole from a 2 pole would half the KV of the motor, but stator and magnet design will change between the pole counts and will affect the KV quite a bit.
