The only thing I know about thermal dynamics is > surface area 
I’m not exposing to air for her. I am at the point where I’m riding hard enough that I’m overheating with internal heatsinks. Going external on 12s build and then likely 4wd HV on bigger board.

Tim’s the one that did it, its worked solid for a long time now.
When you get a chance, could you take a pic please? I’m going to start building my protitpo this weekend.
Muchas gracias
pls dont cut the enclosure
It will probably be a while before I open it up. I’m putting a new battery in it soon, 12s5p, but it still needs a lot of work.
I’ll see if I can find a pic in my photos.
I looked everywhere I can think to look and didn’t find any pics of the inside if the enclosure. I’ll try this weekend, if I have time.
thanks. :). I was gonna ask the same.
This is a picture of the two focboxes mounted to aluminum plate in stock prototipo DSS50+ built by lacroix.
I ordered the pads. then realized you said you prefer a thermal tape. I think it’ll be good though afaict my focboxes are bolted to the aluminum plate.
I like the tape because it’s cheap and you get full coverage. The pads are just as good. My preference is of zero value 
.
No prob, whenever you can. Thanks
Between the Focbox and the plate the best thing is thermal paste, far superior heat transfer compared to any pad or tape
my reading tonight has led me to think that too. I think I may try that route instead.
OTOH the thermal pad that connects the FETS to the case has a much smaller area and is already limited by being a thermal pad. so I’m guessing the case to plate interface can keep up even with a much lower thermal conduction rate. hmm.
It’s hard to say, while they are is smaller, the FETs are hotter than the case, so the rate of thermal transfer between it and the case, even through a thermal pad can be higher resistance, can be higher, and also the cooler you can keep the case, the more heat goes from the FETs to it
Ok, before making changes and doing the thermal interface focbox->plate experimentI wanted to gather some data.
I initially planed to do this on proto#2 but it’s having it’s own issues now with a DRV fault. after previously having blown the FETS on the other focbox.
So, Let me do these tests with proto#1 (10s5p 20700b 20T/62T 155mm tire diameter )
this is my thermal test run ESCs temps shows 77 and 88. 84m climb over about 2km distance. a bit steeper at the end.
it’s interesting the two temps were that different. perhaps I should replace the internal thermal pad before doing the ESC -> aluminum plate experiment.
Hmm. that temp difference correlates with a motor and battery current difference between the two ESCs.
wonder what that is and how it would muck up my experiments. 
so weird… swap ESCs and see if this follows the ESC…
somehow I missed this. I’m not hitting 80c on the bench.
just hitting 80c fairly easy on a hill. or carving hard.
hmm.
Presumably swap motors first step. that’s easiest.
Then swap receiver and CAN setup next…
