Here is the email I sent to medusa:

Hello Medusa Research,
I've installed one of your medusa 36-70-1600 motors in my 11 pound brushless truggy conversion on 6S lipo with a MMM. The shaft sheared off yesterday, about 3/16" into the can. Motor makes a very bad grinding noise when any throttle is applied, so I think one or both of the bearings have gone bad also. The windings look fine, and the motor does not smell strange. My drivetrain is free, and I was running on the street, so I doubt a rock locked my drivetrain. Attached are a couple pictures of the motor. I have about 4 hours of runtime on this motor and besides this failure, I have been very pleased with it. I bought the motor in early february from the RC-Monster store, and I am one of the forum members there, specifically I am BL_RV0 on the forums. This motor is still in its warranty, as I've only had it for 3 months.
Thanks for your time,
Ian Arnold
