Short can. So it is the YCS22-5000. It's a strong motor. I had the YS22-3000 (might be 3600, I blanked out). One other thing, I think the Hyperion inrunners are 4 pole motors and some places states as 2 pole, but if you look inside the ones that have the openings, you can see it's a slotted design and it cogs just like my Aveox 27 and my small Razor motor.
