Just so you all know (and don't blame me if its different for you) but I just lost control of my Twin Hammers and it landed upside down in water completely submerged and this ESC got NO water inside (yes I voided my warranty opening it up to check) which means the case on it site very tightly. I might just be very lucky but just sharing my experience. Also, what is the best firmware to run on it? can I choose ANY of them in the program or will some of them break it?

Very low quality, horrible esc - broke on the second day.

Just updated to latest firmware, massive improvement on the brakes. Car stops so much quicker. Definitely worth doing..

Can anyone tell me if I can easily make this waterproof..if so do I just use Black Jack roof bitumen?

Pull it apart (voiding warranty I guess) and apply either liquid electrical tape OR plastidip to all components. Might be hard with the heat sync but you need to make sure all the gaps between it and the board are completely filled (Dont cover the heat sync though)

Please help, I have put this into my h.king rattler and it will not turn the motor at all and the steering servo is slow to respond and jittery, ESC came with no instructions so Im not sure what to try next.

Another 5 star product from hobbyking. Good overall quality, very light and well made esc. Powerfull fan! Awesome value! I used the hobbywing software to make settings and usb adapter. Forget branded names. You don´t need branded names, I have 20 hobbyking combos at this time, they are keeping better and better. They are excellent!!

love this and the 60A x car esc's , we all know what they are but that should not detract from the fact that they are awesome , super adjustable from very quick to rather slow or anywhere in between, get the usb dongle or hobbywing LCD/turnigy LCD usb programme boxes and set up and change firmware on your pc, not waterproof sadly , no wonder they keep selling out .;-)

Nice Esc, i'm using it with my Xcar 10,5T Motor in 1/10 Touring Car with Hobbywing's V3_110930STOCK Firmware. After 5 minutes of race, Esc it's 35ºC and Motor it's 60ºC. It works very nice, run smooth and its small. Great Work HK! ;-)

For sure, a best bargain price for 120A Car ESC~ with well with Hobbywing firmware & 4 poles motor. Maybe, wire updated to 12AWG is required when the motor draws high amp!
