Unstoppable tail wag

I have a clone 450, spectrum tx and receiver. I'm using a spectrum h3020 digital tail servo, my gyro is a Gy48v. The odd part is it flew great I tried to put this frame in a fiberglass body and it was to heavy so I went back to the regular frame, now it has a bad tail wag in avcs mode, so replaced the gyro thinking it went bad. Well even with the new gyro ( which is different kind from what I had) it still does the tail wag all setting are correct and have not changed since it flew good. Any idea what will make his happen this?

Try decrease the gyro sensitivity (gain)

Might need to be re-tuned , so play with the gain ..
Also check the controls for any binding ..
Rotor speed ? has it gone up ? sometimes if you increase rotor speed it increases the sensitivity of the gyro as the tail rotor has more authority . And there probably is a few other things , but if you haven't changed anything

Well with the digital servo being used it say's to set it at zero, although I did try that and it made no deffrance. And the head speed is the same. Could I have a bad tail servo

Look for a missing or worn down tooth on a gear.

Found it, two parts the shaft that holds the tail rotor was dry and not allowing the steering Mechanism to slide freely. So I lubed it up. And the other part was the nut that holds down the metal pice that holds the tail rotor blade was loose. So I was about to sling a blade off! Guess the old girl was trying to tell me something was wrong
