        How do you mean a 'hot' set up... When I ran it without cooling for 3 mins without planing going flat out at points trying to get it to plane my gps logged 60 amps with the 1.8 3 blades temps on esc 28degres motors about same..

        Will run tomorrow night and report back.. Where's my hatchtape?!?! Might need it if i get over the plane
        just a little obervation.
        if your boat is not on plane and you flat out, your props are cavetating and you dont have much resistanse on the motors witch again dont give you much amp draw.

                  i think his motors arent getting their proper kv's. Its not possible the motor is reaching 35.000k and the boat isnt able to plane with the props he is using.
                  maybe your need to setup your esc. Some timing?

                    I believe 6SHydro is right about the packs wired up wrong. Liam take a pic of your Y-Harness that is used to join both your 3S packs into a 6S. You are running a hot setup at 35,000kv/rpm and you cannot get on plane, is mind boggling indeed.

                    This is what your harness should look like. http://www.offshoreelectrics.com/pro...arness&cat=136

                      Check post #35 looks to be okay to me. In a twin those motors are not too hot. I'm with Randy. Your COG should be at 27-30% of your hull lenght. Measure from the back of your sponson to the front and calculate from there.

                            If you ever find some extra money, ship the boat to me, and i'll check it for you.
                            All your hardware/motors/escs/lipo's are good quality, so this baby MUST be able to become a
                            fast boat.
                            I bet it's only a little thing that went wrong ( esc settings / c.o.g/ or something like that )

                            btw : what did you use to secure the flexcables in the propshafts ?

                              I wouldn't sell it. You will lose a lot on what is probably an easy fix.

                                i used loctite its the one mhz sells for propshafts, gerwin this might be a possibility...

                                what annoys me is i went for mid-high range parts and people with feiago 8xl's are doing better than me
