Then buy a servo ( thing that operates</div><div>the aileron on a RC plane) & attach that on to the spindle of the potentiometer.</div><div>The servo is plugged in to a channel on the RC receiver ( RC receiver needs 5 Volts),</div><div>now when you operate the joy stick on your RC transmitter instead of moving</div><div>the aileron up & down it turns the potentiometer one way or the other, controlling</div><div>forward & back & speed. </div><div>You could have a switch incorporated to change from radio control to manual.</div><div>I am not sure how the radio signals would work inside a metal hull, maybe buy</div><div>a RC to & try it out first! ( good excuse)</div><div>A lot of modern motor controllers have a RC signal port. Jon was looking at a motor</div><div>controller that had that facility, not sure if he bought it.</div><div>Other than that, there is a lot happening in the robotics World with radio controlled </div><div>battle bots etc; they are controlling a number of motors off RC. There may be</div><div>videos or advice on how to do it on their forums; however a lot of their controllers</div><div>aren't capable of the voltage & amperage we use.</div><div>Cheers Alan</div><div><br></div><div><br></div><div><br></div><div><br><br><div>Sent from my iPad</div></div><div><br>On 25/06/2017, at 12:10 AM, hank pronk via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="color:#000; background-color:#fff; font-family:Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:13px"><div id="yui_3_16_0_ym19_1_1498305810363_3193">Hi All,</div><div id="yui_3_16_0_ym19_1_1498305810363_3193">Gamma has this stupid multi wire cable that goes from the electric panel to the hand control box.
