Spirit Pro, Chase 360, HV93i on tail. I have a fast tail shake during fast forward flight. I've decreased rudder gain to 35 and upped piro consistency to 170 and now it's toned down, but I can still hear it in idle 2 (bank 2). 35 sounds low on rudder gain, so can I just increase piro consistency higher or should I continue to drop rudder gain down? Other than that tail seems to be holding well and rescue works as advertised.

thanks in advance, Dan

The problem is caused mostly by:
- too high rudder delay (for your servo 0 may be fine)
- too high piro consistency (165-175 should be good range for your helicopter)
- too tight mechanics
