I've had this motor for over a year now.. And I'm ashamed to say I have not replaced the rear bearing in it until now.. I have one order.. Front, rear, & a new ring actually. Good thing I pulled it apart to inspect too.. Rear bearing has 3 fractures clean thru on the inner race... Couple balls had flat spots on them. Not sure tho.. I could get a few more flights outta this bearing. Lol

Got your moneys worth there:) LOL looks like a lack of maintenance that caused the failure:)

They go out depending on amount of flights.. I should have swapped it out 6mths ago.. I honestly didn't know I should have.. This was my 1st year on nitro... Lesson learned!

You should be changing them at the end of every flying season for good measure. Regardless if they need it or not. Its one of things you dont want to have break during a flight.
