lol no i got my answer the whole meltdown solder disjoint caps or w/e lol. that confusedme!!

CC is 200, but me personally would never bring my electronics to that level if at all possible. I pretty much like to keep my stuff around 150 or less if I can...

Lol, yeah, I'm sure BP's melting point post was "tongue in cheek"...

Funny stuff indeed! All well taken of course!

I still think everyone missed the joke in his post... I'm sure he knows 200 won't melt alum. Imagine an esc becoming arc welder... a dead short. That's what he meant I think.
glad someone caught that :027:

Here is a visual....:036: still waiting for the thermal..

totally my fault though, running 1/4 to 1/2 throttle testing other parts....which is a no no. Wouldnt have happened full throttle. Dont think many controllers would have survived it.

Perhaps I'm missing something, but why would that be a no-no?

Wow, that's the first MM I've seen that burnt. What could you be doing at 1/4 to 1/2 throttle to cause that - shorting the outputs? You know, you're not supposed to weld with ESCs. :dft012:

I don't suppose the heatsink is loose enough to come off now is it? I would love to know the part number of those FETs...

partial throttle always creates more heat/inefficiency than full throttle. The esc's like to be run full throttle. Same as in full scale electric vehicles, you try to keep the cars in 1st gear so they are full throttle at cruising speed for best results. They are most efficient at high RPM, which makes them less efficient at lower RPM...less efficient = heat.

nah no shorts (well..i am sure there was some shorting eventually). It was quite a fire show, had the body glowing white till it was unplugged.

that's crazy!

I bet that the smells good!
