SeaKing 180 ESC...extra cooling.

[ScarabChris]

I was running my 54 Fountain today and had one ESC shut down from overheat. Upon looking at this ESC I feel the cooling sucks on them. Just a tube that runs through. Then you have this huge opening, I know this is for air cooling.

But why not fill the cavity with water running through.

This is what I did and I will see how it works tomorrow.

I simply cut some small pieces of stainless steel, drilled and tapped for the hose nipple. Then roughed the back of the plate and the ends of the opening on the ESC and used JB Weld to fix the plates in place. It holds pressure very well and I have to imagine with water flowing through there it has to cool better.

The last picture shows the new water routing. In the bottom of the new closed in chamber, out the top then through the original useless ports.

Opinions???

Sweet Job!

Thats pretty cool.............im wondering though if your ESC is getting hot and shutting down from running the 1p setup. Your batts may be overtaxed, thus taxing the ESC's and causing shutdown. 2p may fix this, especially now with the extra cooling. Your boat has plenty of room for 2p.

But it's only one esc not both getting hot?

Yeah I was thinking this as well, but I just don't know enough about this LiPo thing. I posted these questions on my 54" Fountain build thread in boat building.

I'll try with 1P tomorrow first and see what happens, if it still gets hot then I'll go with the 2P setup and see.

I'm just wondering why only one was shutting down. Does the timing have something to do with it? I know for sure that one motor spools up slightly before the other.

Plus the motors and batteries were super cool.

What is considered an acceptable temp for these ESC? The one shutting down was at 151 degrees and the other was at like 125.

The hotter ESC may be working harder........taking more of the load, as you have stated one spools up quicker. They are two completely different systems and will not work exactly the same.

If your batteries are cool, your 1p setup is fine..
but it does sound like your escs are not running the same timing?

I don't know what the timing is set at on the ESCs. This is an area that I just don't understand.

If the timing is set different between the ESC's will this cause one to do more work?

Did you pull the original nipples off and check the holes in them? Many need to be cleaned up and/or reamed. Could be that it was not getting good water flow.

ESC's are brand new, boat has been in the water twice and water blows out the ESC discharge pretty hard.

yes

Can someone give me a brief explanation of what the timing is for? The ESC directions don't say much.

there is alot of info on here as far as timing goes... do a quick search, but the leopards you have are a Y wind motor I believe, and again I believe if I am correct they like high timing...... those turnigy/seaking 180's are easy to program, follow instructions and reprogram to high timing on each before you go to crazy.... I would bet this is your problem........

In looking at the Leopard website it looks like the 5692 1340 Kv is a "D" wind motor. Did a search here and I have seen the recommendation that these D wind motors should have 0 to 5 degrees timing?

Any thoughts?

Shows I don't own any 5692's.... Lol, chris then definately set both esc's to low timing.... Very easy to do on turnigy 180's...

I believe the default timing is 15* and could be the cause of your problems.
