Hey jsngnn22, I also have had two or three motors seize on my t28 and Corsair; they use the same motors. If you look closely, you'll notice a set screw in the front bearing mount. The mount is PLASTIC, NOTMETAL and it fatigues and cracks. If you tighten the set screw, you will see these cracks open up. Once these cracks have expanded, carefully fill with CA and back off the screw to mend the stress cracks. I've saved a few PK motors this way. On a few of my PK models, I upgraded the motors with Turnigy. Good luck!
