Spirit System

Hi all!

My TRex 500 DFC has a problem with the tail. It twitches regardless of the gyroscope settings. At low RPM (60-70%) there is almost no twitching, but if the speed increases (85%), the twitching becomes constant, making it uncomfortable to fly. I changed different parts of the heli to remove the vibrations, but the tail still twitches. This does not depend on the wind or flying style.

Now on my Spectrud DX8 the gyros setting is 30% and the tail still twitches. I think that this is a software problem, because if right before the flight you change the gyro settings in the transmitter by literally 1% in any direction, the vibrations become less. But on the next flight everything repeats itself.

Help me figure out how to fix this problem pls.

Hello,

please share your settings file here.
I can check it and help then.

What is your tail servo and governor used?

On tail I use standard for 500DFC servo Align DS525M. I am attaching the settings file.
Governor by stock ESC Align RCE-BL70G 70A.

I also had this problem and it does not depend on spirit.
The problem is the esc, try deactivating the governor of the esc and see if the problem at the tail disappears
