Ya, the ballistic's are pretty good motors after the rotor de laminates and you put sleeve retainer on it to fix it. I had 2 de laminate because novak hardley put any glue on it. Permatex sleeve retainer works like a champ for ever, good to over 500F. Same stuff they use to sleeve engine blocks. Easy fix! Im not sure what novak used but it didn't hold up on two of the motors I had and they never temped over 150f. This guy at the track had a brand new one de laminate and I told him I could fix it in less than 10 min and he didn't believe me so I did and that was a year ago and he's still running it.
