Hi,

I had a chance for a few tests today.
I had my best results with:
- Flight Style: 7
- Cyclic Gain: 55%
- Elevator Filter: 4 (Still have elevator movement during normal forward flight if I use collective pitch)
- Cyclic feed Forward: 4 (starts feeling disconnected)

I also tested Cyclic Feed Forward of 3 but I don't like it.

During normal flight these settings seems to hide my problem, but during hover, it is still there.
Also reduced RPM around 1200 makes it more visible, I fly most of the time with 1450RPM.

Any idea what to check (settings or mechanic)?

I reduced Geometrie 6° tuning by value*0,75, is that too much?

Thanks
Guido

Hi,

I would like to bring the topic back to top.

I was able to solve my issue with the disconnected feeling on cyclic inputs.
I raised cyclic gain to 87%...
I still have the feeling it could be a little bit more but I'm concerned because of possible issues.

My new question is:
Is there any dependency between cyclic gain and 6deg/setup?
I'm still using (number at 6deg)*0,75
Should I increase this number to get a tighter feeling on cyclic or should I raise cyclic gain a bit more.

Thanks
Guido

Hi,

yes, there is dependence between Cyclic Gain and Geometry 6°. For this reason you might need to use higher Cyclic Gains.
Roughly it could mean that with 87% it is just around 65%. Until there is no visible oscillation (in aileron axis) then you can increase.
But actually higher Cyclic Gains could induce feeling that the stick response is delayed. But with higher gain the model should be more precise.

Hi,

thanks for your help.
I will test it and try to find my sweet spot.
