    i guess now i am choosing between SV27 and UL-1 now coz i just dont think RIO EP is fast enough for me unfortunately...

    i have one other question: can anyone recommend a good rescue boat since i dont have a good boat retrieval system...
    My vote goes to the SV27.. you will have alot of fun with this boat and it will get some good speeds with a different prop and good lipo packs
    It's still one of my favorite boats to just go bash with..
    .NAMBA20...Caterpillar UL-1, P-Spec OM29, P-Mono DF33, P-Spec JAE, Aussie 33" Hydro-LSH, Sprintcat CC2028 on 8s, PT SS45 Q Hydro, PS295 UL-1 power, OSE Brothers Outlaw QMono 4-sale, Rio 51z CC2028 on 8s

        Add a lipo shield., move the batteries forward. http://kintecracing.com/Supervee_27_upgrades.html

          thanks man!

          do you use the exactly one with your SV27? did ur boat ever get stalled because it ran out of juice?

          i found this (for 2s lipos) on the internet, they should work right? but does that mean i gotta attach 2 of them since SV27 uses 2 batteries?

          also, how do you connect the white connector to the read/black wires?



          man, i am getting my boat today and i am leaning towards SV27 than UL-1...

            I would lean towards the one i sent you the link for on kintec that already has the deans installed. That way you can take it out and put it in whenever you want. No you dont need two. If you get the one with the deans it has two connections. You plug the esc into the lipo shield and your batts into the esc. Give me a sec I'll take a pic. If you get the one you have listed you have to solder into the esc, not a big deal.

              do you use the same one yourself?

              by the look of the pic, i have to say those battery wires look very THIN, is that gonna be a problem?...

                Nope, I haven't had a single problem yet. I honestly never run my batts until the warning kicks in. I time my runs.

                  Pic 1 is the esc plugging into the lipo shield
                  Pic 2 is the batt connections from the esc plugging into the lipo shield connections then you just connect your batt to the lipo shield

                    how much time do you think i can get out of TWO 2s 28C 6000mah lipos with sv27 with conservative throttle (stock setup)?

                      If your running "conservative" watch your temps. Running half throttle really heats things up and the esc doesn't really like it that much. In terms of run time: http://www.offshoreelectrics.com/conversion.htm

                        thanks, its a useful tool.

                        28C 6000mah only gives me 12 mins of run time.... was expecting more than that...

                        its just when i play rc, i do stop quite often, i dont normally run it for like 20 mins full throttle until the battery dies.

                            i dont quite understand for my rc trucks, a set of batteries can last me almost 1 hr if i play conservatively.

                            boats are different?

                              Boats are power hungry. The constant friction/drag caused by water takes it toll on batteries and esc. You have to have a good "C" rating on your batts. I use 25C & 30C and I'm about to buy some 40C's. Because of this run time suffers.

                                Alot depends on what prop you use..
                                bigger props pull more amps, possibly 70-75amps with a CF48 like I use
