next step

Now would be a very good time to brush some liquid electrical tape on that ESC.

It will be a two-components heat-conducting dielectrical compound. It will be a good cooling system. Some photos will be after work

That is a good idea.

Only photos. If you are has any questions, please ask they.

Ok I have one, what kind of epoxy did you use there? The grey colour? That turned out very well by the way.

It is not epoxy, it's compound. I don't know, how it named at the USA. I was buy it at the radio-electrical components shop. http://www.chipdip.ru/product/kptd-1-1t-5.5-100g/
As i write before, it's a two-components heat-conducting dielectrical compound.

Hi to all! Bad news, ESC was breaked at the first drive on the water.

Further opening showed burned mosfets, four pieces




I will try t replace it and pressurize ESC seconnd time :)

Very like this ESC, nice working, nice construction and nice price and nice wires. Let me some lucky at this hard work

Hi to all!
ESC repaired! Was replace 4 keys (1), 1 resistor 47 Om (2) and 1 chip (3). What is the reason of burning ESC i don't now. First drive will try next weekend.

[Chrisg81983]

There is a reason why you keep killing controllers within the first few runs. If you are totally cooking etti 220's you will most likely keep burning stuff.

If your video of the burnt etti is accurate, and the gallon of water I see in the boat was in there while u were running. I can pretty much guarantee that is what caused the etti to burn. It does not matter what the manufacturer says: about being waterproof. No electronic devices are waterproof at most they are water resistant / splash proof. Electronics and water just don't mix. There are also a few other things I see in the setup that could contribute to it but I would start with the water as being the culprit.

You are mistake. Boat is always dry at the water, it is completely tight . You are see the water In my video with Etti because i was stew the boat after explosion. I was sink it to stop the open fire. It can't be the reason of the burning ESC. You are right, electronics and water can be mixing.

With the flier i think it was defects at the mosfets or control plate (chip)

Was that a newer release esc? Quality control used to suck for them but I know it has been improving

I had a 450amp flier for a 1/5 truck, never worked from the day I got it, getting it repaired and converted to marine in the uk
