    Default Need help

    I'm running a hydro w a etti hv esc and a neu 1527 1.5y motor octura 450 prop on 10 cell and the boat revs out w no load but when I put it in the water for the first time today it can't Rev up.... If I hold the prop out of the water then pull full throttle and hold it, then drop the boat into the water it'll take off like a rocket and hold speed until I let off the throttle. Once that happens it can't Rev out again when the throttle is pulled again. I have tried changing the low voltage cut off from the 10 cell setting to disabled. I have tried changing the timing of the motor. I have tried changing the pwm settings. On the telemetry there is no large voltage spikes. Nothing seems to work. The batteries are brand new. Any ideas fellas?

    Did you set the throttle endpoints on the ESC? Which H&M Hydro?
