Thanks for the tip. I swapped out the tail boom and tail motor assembly, and that did the trick.

I kind of suprised the motor went that quick, I didn't think I had that many hours on it. I also had to swap out the main motor to. Out of nowhere it just would generate enough lift to take off. I swapped batteries thinking it was something wrong with the battery, and it did the same thing. I swapped out the main motor, and with a new tail and main motor, she's flying like a champ.

I hope they continue to offer parts for the MSR since they discontinued it. It seems like I am always replacing parts on it.
