I have only dry tested it and I like how it works but have yet to test its performance in the water. I am also using a gauge in the sub that shows the position of the motor as I have this same set up on my sailboat and it really works well. I can't find the video of the steering one but I am using the same principle to open and close the flood valve for the VBT which I have attached.</div><div>Hope this helps</div><div>Rick</div></div><br clear="none"><div><div id="gmail-m_-5634573380858907754ydpf11f389cyiv1879600528yqt28216"><div dir="ltr">On Fri, Jul 9, 2021 at 3:36 AM Jon Wallace via Personal_Submersibles <<a shape="rect" href="mailto:personal_submersibles@psubs.org" rel="noreferrer noopener" target="_blank">personal_submersibles@psubs.org</a>> wrote:<br clear="none"></div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:"new times",serif;font-size:16px"><div></div>
<div dir="ltr">I've thought about that as well but haven't got there yet. A simple potentiometer connected to the rudder would be enough to give feedback regarding its position if I can come up with a way of waterproofing it. I recall Alan trying to deal with this years ago and not sure if he did find a solution or not. In terms of returning to center position, just not there yet. If anyone has suggestions, I'm open.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Jon</div><div dir="ltr"><br clear="none"></div><div><br clear="none"></div>

<div dir="ltr">Nice work Jon; well documented and helpful. I have found that to make fly by wire work for control surfaces, you need a position sensor and/or have the ability for the control surface to return to a neutral position through the joystick sending out a centralized position signal. What are you planning to use on your boat for rudder feedback?</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Thanks for this excellent contribution to site.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Cliff </div><div><br clear="none"></div>
