custom Quark case design

[nieles]

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

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

[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.

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.

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

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.

[Maxxman]

Don't worry about the extra room for any caps.
I just wondered and was also a little confused about the design.
Anyway if i wanted to add some it is still possible.

[zeropointbug]

Well I highly recommend adding more caps, and S&T does as well.

Mike replied back, he recommends simplifying it more... like no rounded edges, make edga chamfer instead. And the bottom where the fins meet the motor mounts had to be changed.

I'll update once refined some more.

[Maxxman]

it doesn't really matter much,

but i may add some as many people around here, including S&T as you mentioned as well as others, say that it is better to add some if you can.

the capaciters in the Quark are 330uf low esr caps aren't they.

Also in some ways having squared corners would be better than rounded as you would have more material, therefore theoretically a larger surface area and machining costs a bit lower.

[snellemin]

How much would this cost? Really nice case designs.

[zeropointbug]

Thanks. :dft009:
I have not got a price back yet for it, from Mike. Although I am not done designing it, and MIGHT make it flat bottom so it can be used with his Monster esc mount. We will see.
