I have experienced very small P and D values, can this be?

Hi,

in the last few days I have flown the VFF P and D gain values for the swashplate on my Logo600SE according to the tuning instructions. I use Futabe BLS451 servos on the swashplate.

At the D value 0.002 the helicopter oscillated. I then set this to 0.0008 for safety, because I thought I could already see slight oscillations at 0.001.

With the P value 0.04 the heli has already oscillated. I have now entered the value with 0.02.

Can it be that a heli already starts to oscillate at these small P and D values?

Heri,
These values are very normal for heli’s. That is why they are hard to tune.

@bnsgeyer Hello Bill,
thank you for your answer. So I know that this could be normal.
That reassures me.
