custom Quark case design

[zeropointbug]

Here is a pic of what it more would like assembled (with stock plastic covers of course).

cool but what about an version without the slots for cooling but solid aluminum

this will make the case significant cheaper
or only slots on the under side is also enough for me

Mine is 84mm long.....the heatsink, you dirty minded people.

That design is looking pretty good, if it has a flat bottom then it would be good for mounting to the chassis of a 1/8th, but then if it had fins on the bottom and mounting holes on the end there would be one less thing for an e-maxx driver to buy. Personally I have the RC-Monster heatsink already, and I have a 1/8th that I will want to put the Quark in soon, so I like the flat bottomed version with screw holes underneath.

[zeropointbug]

Geez, I was hearing that ppl would rather have integral heatsink on bottom? You will still be able to mount the bottom on anything, it is flat heatsink, no problem there.

I will see how much a heatsink bottom will cost, and one with flat bottom.

thanks Patrick

hey i have got to say that it looks great.
would be interseted in getting one if the price was right.

Would you rather have integral heatsink on bottom w/ mount screw holes on each end of case?

I like an integral design.

[zeropointbug]

Yeah, me too. I think it's best keeping to one design, and integral is my middle name.

This is what an R/C MT esc should be with this heatsink, the Quark... even if S&T made the top set of FET's coupled to the chassis, that would be worlds better.

CAD program says the outside surface area is roughly 300cm2. That should do the trick. :017:

So maxxman, nieles, ssspconcepts, patrick, A4DTM, jhautz are you guys seriously interested in getting one for yourselves?

Again, the design is not to specs, I don't have my Quark back yet from S&T, so it's going to have to wait for it to get here.

Does anyone happen to know a free thermal simulator program that I could use on this case?

[Maxxman]

sorry,
no idea's about the thermal simulator program, but if the price isn't sky high i may get one, as they look sick!

there was going to be some room for some extra capaciters wasn't there.
You say that the outside surface area is around 300cm2 but i was wondering what the surface area was on the original one.

Thanks.

[zeropointbug]

The more ppl we can get, the cheaper it will be per unit. Mike still hasn't replied back yet though.

The stock Quark case is roughly ~60cm2, but also the thermal coupling between FET's and case is very poor. So this one has 5 times the surface area plus superb heat transfer from top and bottom FET's. I can bet under normal MT conditions the FET's will only get 10 degrees (maybe less) warmer than ambient temp, but just a guess.

Oh, there is no way I can make room for extra caps on this, it would simply be too large. Caps are going to have to be added to power leads externally.

[Maxxman]

try e-mailing him again

i e-mailed him some time last week maybe thursday and got no reply.
So i sent it to him yesterday and he came back today. he also told me that he was having,
"a few struggles with the site lately(wacky computer/web stuff that I am largely unfamiliar with) – I apologize for delays in response relating to this."

i am still wondering if therewill be any room for extra caps.

zero, sorry, I'll send you my files when I get home tonight. I'm still playing w/ the design some, here's where I'm at now.


I don't have time to mess w/ it right now, but do you know if COSMOS will do thermal simulation?

[zeropointbug]

That's alright, you don't need to send them. I think the design I am at now is pretty good, I'm trying to keep in mind CNC work, keeping the actual bit/flute in mind. Keeping it relatively simple

I really, really like your design, but the top cover will add a lot more cost to it... :030:

BTW, what are you using to render your parts? Is it built into your CAD?

[zeropointbug]

What mount is that it is on?

haha np, sorry for the late reply. I'm not planning on getting a new case for my quark, as it's already 1/2 blown lol.. I'm just waiting for it to die, then I'll go Teken or CC. I just enjoy modeling, and I figure I can use stuff like this in a portfolio. I've designed alot of stuff that I'll never get made, simply because it'd be way to expensive for me. Here's a perfect example of a project that I really enjoyed designing, but would cost me an arm and both legs to get made: http://www.rc-monster.com/forum/showthread.php?t=1421

I'm using PhotoWorks to render, which is built into SolidWorks. I've got quite a few other renderers, like Maxwell Renderer, with a plugin for SW, so you still render in SW, but it uses the Maxwell engine. as well as Brazil R/S, V-Ray, and Electric Rain, but those, I need to export the part, and import it into 3DSMax, and depending on the renderer, I need to use different versions of 3DSMax.. so I havn't played with them yet. Maxwell works in SW, but my machine's not up to snuff for high quality renders, so it tends to crash SW on me..

The motor mount is from my XR8 project. Here's that thread: http://www.rc-monster.com/forum/showthread.php?t=3489

[zeropointbug]

Cool, I like the chassis design.

Yeah, I guess you can't even get your Quark board out of your case right now! :eek: Too bad.

maxxxman: There will be no room for extra caps inside the case.
