Turnigy Marine 120A Brushless Boat ESC

Turnigy Marine 120A Brushless Boat ESC

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.

I'm in the EU, and there used to be a 'product is available in warehouse near you' on this product-page.. Now it has been removed I see.. Regretable how fewer and fewer products wind up in the EU warehouse..

Possible to stock in european warehouse?

I bought 2 of them and found that they don't directly switch from forward to reverse driving. To switch from forward to reverse, you have to go to reverse (motor will only stop but not turn reverse), then to neutral, and then to reverse again.

How can I achieve that the ESC switches from forward to reverse directly? Is there a firmware update? Do I need a flash adapter, where can I buy that?

program brake [none] #1 try that...

The ESC doesn't allow to program "brake [none]".

These ESCs are used in boats that have FLEX SHAFTS. They Use a Double Click method for reverse to keep you from damaging the Flex cable when you slam it to Reverse. All Boat ESC should be this way.

That may be true, but even just a brake can severely damage a flex-shaft.. I can't really see a reall application for a brake in a marine ESC.

Can I use it on my Spartan as a replacement?

This ESC working perfectly with 2s lipo battery. It starts very fast, no lag. It have main programing abilities, a lot of types of timing. Very powerful 3A 6v BEC. It is the best ESC which I have. I recommend it for everyone.

I forgot to say that it is waterproof and it have amazing water cooling system which is very low weight. And it haves very huge capacitors which helps to start faster.

The version HC is shipping now has aluminium watercooling tubes, and smaller capacitors: 390 piko Farads 35V.

All wires are 12AWG.

This ESC is great. I highly recommend as a replacement for the SV27 ESC. Makes the motor 10 times smoother at low throttles.

These have great performance, and actually put out more power than they are rated for. Mine is running a 580L sized motor in a 32" mono boat hull. Even after it was fully submerged i let it dry out and it work flawlessly.

Very highly recomended
