TURNIGY marine ESC's are built with USA IR mosFET's for long run times and less heat.
Boat esc's have a different requirement to air or car esc's. Their need for sustained high-amp draw makes plane esc's unsuitable and car esc's with large amp spike capability, unnecessary.
Thats why TURNIGY marine esc's are designed purely for boats, and coated in anti-static then water resistant laquer to prevent shorting should the esc get wet. They can handle sustained high amp/volt loads and handle heat better than a car or plane esc.
What makes this ESC better than others?
-Well designed MCU, with efficient code makes for faster sync and accurate timing.
-Fast clock cycle MCU combined with efficient code means 100,000rpm cpu cycle*
-Efficient FET's reduce heat and deliver sustained switching at high amp/voltage.
-Well designed PCB (6 layer) and circuit diagram handles high-amp without burnout.
-Large motor comptability. Smooth starts, linear throttle curve.
-Active water cooled heatsink that actually works.
