Default Another 3G Tail Wag Issue

OK Heli Gurus, I need help. I have a 3G on my 450 Sport and no matter what I do I cannot get rid of my constant tail wag - here is what I tried:
Made sure belt was plenty tight
Made sure t-pitch slider was smooth
Made sure no binding in t-servo pushrod
Gyro gain set on Aux2 with endpoints
Moved ball on servo arm both in and out
Set the gains all over the map.

This is running wiht a Futaba 9257.

Any bright ideas/suggestion would be much appreciated.

Thanks

3G? 3G uses gear channel not aux2, that's for 3GX.
You can also tighten the belt to much and cause escessive vibes.
With the tip of a driver the belt pushed to the centerline of the boom with moderate pressure is about the proper tension

Your welcome.
LOL, that's why I went to all TT. Got tired of checking and adjusting the belt everytime the temps changed.
