Some news from the project....
I finished installing my prototype and did some first sea trials.
First some pics

I did an all in one box, to be mounted outside. Actuator is an older raymarine ST4000.
Using no rudder feedback
My exp so far.
Sometimes it works like a charm as seen in the little video, but it is not stable.
- Sometimes the pilot starts to leave course and does nothing or much to less correction to go back to desired heading
- Course keeping is not tight enough, correction starts mainly after after ten deg off
- The compass direction is not always correct, cali seems to be fine, but after setting the offset the course differs about 20 - 30 deg when moving to another direction.
- Making changes in the desired heading when the AP is engaged does nothing. No reaction at all, even if I change 50 deg port p or stb
- When engaging the AP does move the control arm about 5cm and does not compensate this back
I tried to play with gains a lot, mainly D, P and DD , but a total satisfaction is not reached yet.
Any suggestions regarding above problem would be helpful.
Thanks and Ahoi
