    Frankenesc

    I had a fellow contact me from far away inquiring about my crazy esc in my rivercat. He wanted one like it for his rivercat he's building. Well he talked me into to fixing one up for him. I just wanted to show this thing, it turned out pretty nice and I'm getting better every time I do one. This one hasc (3) 1000uf 50v caps on the esc and then another 5 in a bank I made. Same as mine. Wires have been upgraded to 8ga. Then a nifty little pig tail added for a bec (I don't run the bec in these controllers on 6s and higher....bad for it I feel). Then I modified some 6.5mm castle bullets and soldered then directly to the posts. Coated everything with liquid electrical tape....and done...Check er out

      Nice Travis ,

      Isn't that a T-180 w/ a 4 port cooling block turned 90° so the caps don't interfere with the water lines ?. I've got 5-6 caps that I picked up from kintec, & I was thinking about making a bank for my 120a support esc that I picked up recently

          Does adding extra caps help with load handling ?

              Hi Chris, in a way, yes it does.
              I am not a esc/cap expert, but in a nutshell here's the way that I understand it. When you're running the cells power the caps and the caps power the ESC, but the cap bank is more for when you cut power and let off the throttle. It's my understanding that a boat drifting forward still under momentum cause's the prop to turn and this can cause power feedback that can damage a standard ESC without a cap bank on it. On a ESC with the cap bank the caps are able to absorb and dissipate the excess feedback and stop it from reaching the ESC & damaging it ...

                  They also help with the voltage sag, which causes the amps to jump up because the battery's can't supply the ESC fast enough.

                      It's a t180, but the cooling block is its normal position. When I changed the caps out on it, I did lay them down.

                          Correct. That's my purpose of having them
