Could we get rid of the 2-plate design please? I did not like having an extra surface to add thermal pads / thermal paste to, and it made setup pretty messy and annoying.
Of course, some ESCs like the maker X ones require such a design, but Stormcores, Trampas, unities don’t.
I thought the 2 plate design was awesome for ease of customization, like using the heatsink for a single ESC and a BMS, for example.
I totally get your frustrations with the mounting plate design. I am open to a design that gets rid of the mounting plate, in fact, I even ran a small batch of storm core Heatsinks with counterbored mounting holes for another vendor.
There is one main problem. Once you have even a few different hole patterns, the top surface looks like a mess, and you have giant cutouts in the fins. So as of now I’m leaning towards a similar mounting plate setup, unless this issue can be solved (without several variants).
Mounting plate was awesome and the custom made offset one you made for me was great. Don’t lose it. Heatsink hole centred on enclosure segment and esc offset inside the segment. Allowed 2 extra p groups to fit in that segment 
Maybe make it so that ESCs that require bolts from the bottom have the double mounting plate, but ESCs that can have bolts from the top (like stormcores) just have threads in the first plate, so that the middle plate isn’t required? 
Did you ever get your prize?
NOICE!
The storm core takes screws from the bottom (bottom of the ESC, top of heatsink), the unit itself is tapped. But, the spintend just has through-hole mounting points, so those screws would need to interface with tapped holes in the heatsink. Most ESCs have tapped holes on the bottom (stormcore, unity, etc…), so tapping the heatsink or mounting plate doesn’t help. Sorry, maybe I am not following what you are saying?
It was a process to get them there lol. I had the package returned twice
Also has 2 wings on the sides for bolts that come from the top, that’s what other heat sinks for it use.
they can also take screws from the top. Is the reason for not using them wanting to maximize clamping pressure in the middle of the SC’s heatsink?
Ah got it. When I was working on the mini, a few people mentioned that they would prefer using the four tapped holes (just more points of contact and more secure 
)
Yeah.
But, I am open to changing it if this isn’t a problem.
That’s also where you want to cool the thing (well okay, technically mosfets are a bit to the side, but still), so you want to put thermal paste / a pad there. Cutting holes for bolts isn’t that ideal.
Using thermal paste would solve that but I’d imagine some people would want to deal with the mess. Thermal paste also benefits from more pressure, so thermally I think middle holes will always be superior (although maybe not in a meaningful enough way to justify the potential nuisance of paste vs a pad)
I’m pretty sure the spintend housing does have some threaded holes, but mine is currently crammed into an enclosure. Even if it doesn’t, you could still screw upward into some nuts on the top of those holes.
Bolt and nylock nut through hole.
Epoxy nut in place. Wait 4 days.
Remove bolt. Enjoy new threaded hole.
Tap hole for helicoil.
Insert helicoil.
Enjoy new threaded hole.
Best part is, if you ever bugger the “thread”, replace the helicoil.
I don’t know about threaded holes on the unit, but since it has through-hole mounting points, the best option is to screw the ESC directly onto the plate (tapped holes in the plate).
they’ve arrived and have set em up on my 4wd build. On BNM1s.
