^^^^I'm willing to bet those 2 polers have twice the kv(rpm/v) as any 4 poler available.

What was stated above about frequencies may be correct, but it still comes down to kv and voltage as to how fast a motor will spin.(but not how quickly)

The "max frequency" thing has me wondering. Do we ever "max out" the pulses from an esc? Maybe BrianG or Pdelcast can answer that one. Regardless, a 2 pole would be twice as fast as a 4 pole, but at operating frequency that would be milliseconds.

So, in conclusion, maybe "on paper" per the "max frequency" theory a 2 pole would spin quicker, but in the real world human reaction is slower than the advantage so it's a wash.

Maybe snellemin's experience in the real world of r/c drag racing says it all, but the kv's would need to be the same to make an a/b comparison.

Hopefully someone with answers will chime in.
