If I had to guess, it wouldn't be profitable in making repairs... mostly because people aren't going to be willing to pay a reasonable price for hourly work. I've got a CNC and there's only been 1 time where someone has taken me up on an offer for custom services. In this day and age, folks typically expect to pay the same price for a mass produced product and don't consider the level of work that goes into manual labor. Generally it will be more cost effective to replace than to repair.

Regardless, it may be worth contacting HobbyWing or Tekin and explaining that you have a competing brand of ESC that has gone bad and see if they are willing to offer you a discount to trade up your old ESC for one of their new ones... chances are this cost will more than likely be less than if you were to send it in for repairs ;)

I have sent hobbywing a message to see if they can help.

Hopefully they can.

If not still hoping someone out there can.

Thanks

If the HW thing doesn't work out, let me know.

So I was 2M qualified (soldering to NASA standards beneath a microscope) when I was a squid. I still do some repair work every now and then. If you do not have the part numbers of the obviously failed components then you will need a schematic. Most companies aren't handing those out. It also helps with troubleshooting.
Problems usually show themselves where they let the smoke out, but sometimes, it was just symptomatic of another problem or failed component.
I have my own PACE Station and ESD station set up. I can do some SMD stuff, but limited. About the only time I won't try to repair something is when it was waterproofed... getting through the conformal coating (usually epoxy) is waaay too time consuming.

Take some close up pics of what you have and I'll take a look... not going to promise anything though.

Jelly, doing SMD work was something i always wanted to try but damn does it look tough. Sadly most things arnt worth fixing know a day's unless you get it free and its something simple.

The reason you don't see people offering to repair esc's is because there really isn't any money in it. I also highly doubt any of the manufacturers would ever give out schematics to make it easier to trouble shoot them. With the cost of a lot of esc's these days you could easily exceed 50% of the cost of a new esc. I've fixed a few esc's for friends that had relatively simple and obvious problems but beyond that it's not worth it.

That's good. The US branch is working on damage control after experiences that several have had, including myself.
