HK450 UPDATE:

found what I think to be the issue with the tail....

Well, Dave was right "BACK TO BASICS" First, Read the instructions! It turns out I had the Telebee gyro mounted incorrectly, (However, no where in the instructions does it mention correct orientation when installing the gyro.) The correct orientation for the Telebee Dual Rate Piezo Gyro is with the label facing left, right, front, or back; just as long as the label is not facing up towards the sky. Figures, I mounted it like my GY401 with the label facing up! I was concentrating so much on the programming that I missed an error during the initial build and installation of the electronics.

Here's some pics of my HK450 with the correct mounting of the gyro....
