Anyone use Kershaw Designs 550 Crawler Motors?

[mazdaprotege4]

I have a Clodbuster with M&L Chassis (that is currently setup for Titan 550 motors) but I am looking for something a little different because the Titans are just too fast (at least I can use them in my Twin Detonator). I was looking at Lathe motors, but I don't really want to spend $40 plus shipping for something I am not sure will fit the bill. I have found these Kershaw Designs motors on eBay (2 for $24 shipped)

Does anyone use them? If so what do you think of them and what do you think it compares to in terms of other crawler motors (does it perform like a 35t, 45t, 55t, ect)

Thanks for all the help!

Looks and sounds similar to this http://holmeshobbies.com/product.php?productid=38&cat=17&page=1
Seems a little slow at 460kv.

Those are stupid slow. 450 RPM/volt is like a 75 or 80 turn motor, your rig might do all of 2 or 3 MPH.

Thanks for the info, I guess I will have to spend a little extra $$ to get a 35 or 45t motor.
