Well it still does it, more frequent now than before. The tail let go after about 5 min. into the first flight, then held for a about 1 min before it let loose again. After spending a lot of time on the set up process, I'm beginning to think that it is either a bad gyro or servo, or a mechanical problem. I've looked over the tail assembly pretty closely, and can't find anything that looks cracked or broken.
