Hello p-51d !
I would assume to reduce the headgain or to set the new position headdamping a little bit up -
Or swashplate Integral is to high this must be tested...
I think the heli is not dolpheneing if so then elevator filter...
Best regards

Hi Matthes61
Thanks for your advice; I'll check and change the mentioned parameters accordingly...
What do you mean with dolpheneing ? ( moves like a dolphin ? )

Hello p-51d !
Your setting-file would be helpful as Tomas said -
Dolphening is the tendency of Up and down as an Dolphin moves - for example you make a looping and at the end of the looping you get in the straight flight an up and down as an Dolphin swims -
Best regards
