I am hoping to get it up on a plane and a run time of 30 mins. Is this run time achievable and realistic?</font></p><p class="MsoNormal" style="margin: 0in 0in 0pt"><font size="3" face="Times New Roman">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?</font></p><p class="MsoNormal" style="margin: 0in 0in 0pt"><font size="3" face="Times New Roman">What would you recommend for batteries Gel cell or NimH cells? If NimH how should the pack be built; 10 cells in series = 12 volts but how many in parallel to achieve run time?</font></p><p class="MsoNormal" style="margin: 0in 0in 0pt"><font size="3" face="Times New Roman">Finally can you recommend a ESC that can handle the above?
