Ebb,
Actually I did make some videos of my self steering system, which feature studio narration and background music, I cannot post those on-line for various reasons. I have used two of them in some for the classes that I teach. I could potentially share one or more of those videos with you in a Zoom session.
However I built a web page devoted to the subject. The URL for that page is: http://www.solopublications.com/sailariq.htm
The photos are small to preserve band width, but the narrative explains how to build such a system. If you would like, I can send larger versions of some of the photos to you by e-mail.
Back to rudders, I understand your point. I merely wished to say thatI have not felt a need to alter the original location and/or design of tiller.
My motor is clamped on the riser (motor mount) in the lazarette, but the handle does not protrude forward through the small front hatch aft of the tiller post. By the way, I installed a permanent louvered vent in that hatch to promote air flow in the engine compartment. You can see the bottom edge of that vent in the photo that I posted earlier on this thread. Instead, the motor handle protrudes upward and slightly forward of the large to lazarette hatch. It does not interfere with the traveler or with the tiller in that position. If I choose to do so, I can close the hatch to rest open the end of the motor handle, but I usually don't. Of course I cannot close the hatch fully with the motor running. After I shut the motor down, I just fold the handle back and then close the hatch.
