All my Medusas came with flat spots: 36-50-2200, 36-50-3300, 36-80-2000. And I got them all from Mike.

Thanks. My E-Sav won't be my last project so I needed to check out and join some other forums with good info and quality folks.

My 036-60-3100V2 Medusa did not arrive with a flat spot, purchased direct from the Medusa Website. I've had other recent dealings with them and have spoken to their reps on the phone so I'm happy with their customer service so far. I had heard it mentioned before that the motors have been found to come with flatspots in some cases and not in others.

To be safe check with the vendor you decide to purchase your motor from. Could be RC-Monster specifies flat spot for items they stock.
