you buy a used motor from me... come on here post your wonderful setup then when you run the motor over what its max rpm is and after you run it for more then 30 seconds in your paypal claim you want your money back......

you ran 1 run you had the carrier fail that would cause an abrupt shock on it and damage the bearings in the motor. i should not be responsible for you not running the motor within its specs. i ra the motor on 5s without any issues.
