Designed specifically to provide a solid, hassle-free performance, Shark programmable brushless marine ESCs offer high quality components programmed with ZTW’s mature software at a price that’ll have you reaching for your bank card. Now sporting super-fast 32-bit processing power, each controller is water-cooled, waterproof and packs a built-in switch-mode BEC. But that's not all. Featuring over temperature protection, a high-throttle safety function (that prevents the ESC from arming the motor if the throttle stick is not fully closed) and two running modes, there really isn’t a better alternative for those who seek an affordable fit 'n' forget solution.
 
 Features
 Features
·       Adopting new generation craft on the MOSFET, low heat generation, withstand large current instantly, and high reliability.
·       Super smooth start up and accurate throttle linearity makes the ESC suitable for all kinds of RC boat models.
·       Adopting 32-bit microprocessor affords greater processing power and faster input signals.
·       100% waterproof.
·       Water-cooling system ensures ultra-efficient heat dissipation.
·       Light and compact.
·       Multiple protections: start-up, over-heat, low-voltage cut off, signal loss, phase loss.
·       Power arming protection (prevents the motor from accidentally running when switched on).
·       Auto throttle shut down in signal loss situation.
·       Supports high RPM motors and compatible with most motors in the market.
·       Adjustable SBEC 5V/6V output voltage provides more powerful power to the servo. 
·       Programmable via phone app or LCD program card.
·       Two running modes – forward / reverse and forwards only.
