    Throttle Fluctuation

    Hi, I'm running 25" with a 88 max amp motor, 120 esc and two 3s 2200 mah 25c lipo batts. When i run the throttle the speed will fluctuate, sometimes turn on and off. [email protected]

      Check your CAPS on the ESC .... Have a look to see if the ends of the caps are rounded , cause they should be flat , this could cause your problem , just because your motor is rated 88 amps ,it could draw double that by over proping ....

            Caps

            If the shiny end of the cap is bulged out the cap is NG and needs to be replaced

                          Throttle Fluctuation

                          Would my receiver have anything to do with motor cutting in and out, the servo for the rudder is working fine.

                              Are you running the batteries in series or parallel....did you flip the hull and components get wet?
