I am new to the forum; but will watch with interest your build as I too am about to build a Higgins .
<p class="MsoNormal" style="margin: 0in 0in 0pt">The PT boat is at a scale of <st1:time hour="13" minute="20">1:20</st1:time> so therefore will be about 48” long and guessing at a finished hull weight of 2 lbs .I am hoping to get it up on a plane and a run time of 30 mins. Is this run time achievable and realistic?</p><p class="MsoNormal" style="margin: 0in 0in 0pt">I am considering Gaupner speed 600 or Astro marine 425 motors running on 12 volts each; with all 3 running forward and only the ctr<span style="mso-spacerun: yes"> </span>capably of reverse. Will these motors achieve my desires or will smaller motors work?</p><p class="MsoNormal" style="margin: 0in 0in 0pt">What would you recommend for batteries Gel cell or NimH cells? If NimH how should the pack be built to achieve the run time; 10 cells in series = 12 volts but how many in parallel to achieve run time?</p><p class="MsoNormal" style="margin: 0in 0in 0pt">Finally can you recommend a ESC that can handle the above? Will I require a ESC for ea motor?
Awaiting your thoughts</p>
