Hi, i have the Spirit since last Year, this is for me the best Solution, works great.
I just have a question, my Logo is shaking @1600 rpm, can i go down with my cycle sens to 20, now i am @30.
@ 1950 cycle sens is 60 no problem, @ 1400 @ 30, with no problem.
But i think the Head damping of the Logo 690 V2 is to Hard, for this rpm.

Hi I have Logo 600. And it also shake at some RPM. I changed dumperers to medium which lower RPM when shake occurs outside my usage range. Or try increase or decrease problematic RPM about 50-100 it can also help

You can also verify if the Geometry 6° value is configured precisely.
If it is too high, it could induce oscillations.
But decreasing Cyclic Gain is usually not solution of this - usually if there are aileron oscillations, it is caused by head dampeners.
But as TomasN described, changing RPM just little bit up or down (out of resonance) can fix it completely so that even with high Cyclic Gain there will be no oscillation.
