Pics of the Hacker Sport ESC
 

Remember the topic that got confusing after a while regarding the Hacker car ESC's and Jeti's.

I went out and bought me a Hacker car sport. Received and opened it up today. I am surprise to see that there are 3 single sided power boards, whereas the mamba has 1 dual sided powerboard. The caps are rated at 50V@330uf. I counted a total of 54 fets(each layer having 18 fets). The heat is tranferred through some thin thermal tape between the boards. I have yet to run it and see how well it does.

Don't you mean the caps are rated at 50v and 330uf? Still looks like a monstrous ESC.

yea, I meant caps. Was kinda late when I posted it.

Thermal management looks ok, but not ideal. I can see the lower FET layer getting quite a bit higher in temps. IMO, the CC HV-110 method of heatsinking is probably the best example of effective thermal management in a multi-layered board I have seen yet.

BrianG, you are like the pee in the cheerios. Did you work in quality control somehwere? I am not dogging you, it reminds me of me. Plus we are both Brian G so it's all cool. Your posts just crack me up, even when they're not meant to.

lol "pee in the cheerios". Yeah, I guess that's me. :oops: Whenever I get something, I'm always trying to find ways to make it better/more efficient/etc.

In my last job (Ops Mgr for Lottery vendor), I had to do people management, project management, Software QA/troubleshooting (and some resulting development), and PR - so yes, I did some QA.

The toughest of them all, especially if you have a majority of women. I have always said that I would rather manage 100 men than 3 women. I have had women managers agree with that statement as well.

I could just sense the QA in their somewhere, as I have that in my background as well.

Done well, but fets quite old...

Similar design, common problems as BK-Electronics ESC's
- flaws of mass production and bad design reviews

What do you have in mind Artur? I have a Hacker Master Car Race that might need some of your magic.

I didn't have a mojority of women, but I did have a few, and you are right. There is a management saying: "You spend 90% of your time with 10% of your staff". Yup, that 90% went to the women most of the time.

I'm not trying to be sexist either. Hell, my boss is a woman and she does fine.

Mine needs the magic touch as well. Tested it out today and it warmed up pretty quick. And it's set on the 60A limit. I'll mess with some more and add 2 additional caps and see if that helps a bit.

I installed mine in my TC3 with the same gearing as I had with the HW controller and the Master Car Race also got hot quick. snellemin, since you have opened your already :lol:, would it be possible for you to get a part number on the MOSFET so I can find a nice match for it?

I'll take of the heatsink for you, after I find another piece of thermal foam at work. I just installed two 1000uf on the esc and it was a bit cooler then before.

That would be nice.

Same thing as with MambaMax.

I re-worked old, thermalled BK-Electronics ESC with copper plates in-between pcb's and now it works much cooler, plus caps and zener (I am thinking about an option to change zener on-the-fly based on battery voltage).

I can tune your ESC, but that would be after May,24.
