One has 20 magnets on the inside cercumference of the bell an the other has 28. As long as the motor delivers it doesn't make much difference although I suppose the 28 pole motor might deliver power "more smoothly".

I hear that the number of pole is in direct proportion to torque and is in inverse proportion to rpm.

I am not sure. But I think the purpose of 20 poles is to approach to YS 170. So the recommended prop is APC 20 X 10.5. It means higher rpm than 28 poles. Both will have equivalent power.
