I come back to you regarding my configuration:
Align Trex 450 dfc        
esc Yge 35lvt

Brain 2
I am using the external governor mode.
The helicopter is working fine but I cannot adjust the gyro gain from my Spektrum DX6 G3 remote, I tried 0-100% and the tail continues to oscillate ...
What is weird is that if I unplug the RPM sensor plug on the brain 2, the tail does not oscillate anymore and is perfect !!
I can't find the cause??
thank you in advance

As we had already explained in the other post, it is not possible to use the ESC governor and the Brain2 governor at the same time, otherwise due to the inevitable different response times of the two governors the two governors will conflict with each other and generate oscillations.
These RPM oscillations can be seen, verified and evaluated from the RPM charts of the Flight Logs. Until now, however, no Flight Log file has ever been sent to us for analysis.
Disconnecting the RPM sensor from the controller removes the feedback to the Brain2 governor which then stops working and leaves the ESC governor active. It is better in these cases to deactivate the Brain2 governor by removing the checkboxes "Use governor" in the Wizard panel 13, or deactivate the ESC governor.
Without a flight log file in which the tail swings occur together with the configuration file used during that flight log and the event file, we are not able to do the problem analysis and give further information.
