Turnigy Marine 120A Brushless Boat ESC

Turnigy Marine 120A Brushless Boat ESC

TURNIGY marine ESCs are built with USA IR mosFETs for long run times and less heat.
Boat escs have a different requirement to air or car escs. Their need for sustained high-amp draw makes plane escs unsuitable and car escs with large amp spike capability, unnecessary.
Thats why TURNIGY marine escs 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 FETs 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 have bought this esc for my boat and yesterday following the manual I calibrated the throttle range holding the trigger to full power and then connecting the boat Lipo to the esc. When I checked the esc I saw that I had to change the throttle channel to reverse because my prop was rotating backwards. After that the brake was working backward. I tried to calibrate the esc again as I did the first time but it wasn't possible. Does anyone knows if I calibrate this esc once how could I do it again?

Could i run this in a glider/sailplane or must it be water-cooled?

Hello alll* I am wondering if the Turnigy nano-tech 2700mah 3S 65~130C Lipo Pack will be ok to use with this ESC?

Do you need a program card to use this speed controller ? and if I do what program card do I need ?
 Dirk 8 points
You are able to program the ESC without a program card - under files you will find instructions.

not recommendedfor 6s... prefer 180a

i have seen this esc used on 6s with no problem. just have to watch current spikes. as with any system

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
