        How do those batteries all fit? Have you run any 2X2S packs?

          They all fit fine
          the 65c are tight but slide in and out with out removing anything
          2s packs dont give me the amp draw or run time I need with the 2000kv and 2200kv motors
          The did ok on the stock set up but i would do nothing less than 30c even with stock if you want them
          to last at all

                Here is a clips of a mystic pnp I sat up for a friend this summer. in this clip Stock motor, prather 220 prop and a HK 180 esc.
                First 45-90c and then from 1,30 min 65-130c. Boring clip but one can hear the increase in rpm with the higher C ratin packs.

                    How in the heck do u fit 4s packs in there?? I just looked and don't see how I could fit them in there with stock trays? Did u take ur trays out and put the batteries in the bottom of boat? If I put 2 2s packs on top of each other are they equal size of 4s??

                      Nahh, 2x 2s stacked and a 4s pack can differ in size. I had som zippy 4000mAh 4S1P 45C once, and they were a tight fit without modding the tray's. I use 4400 and 5000 2s pack's
