Cool it. LOL they are just shafts. The longer the better! I bet girls will choose the motors with the longer shafts. It is their instincts. kidding. Dun kill me for me.
Oh yeah!!! nothing wrong with the shafts.. and nothing wrong with the motors either.. but when you spend that kind of money, it's about quality/workmanship. Know what I mean, first a shaft, then a bushing, then what next?...
