Quark fried, blown capacitor...

OK, here are some pics of my current setup. It isn't real pretty. I just wanted to keep it simple. I don't like the fact that the fan is so high on the chassis. I'm going to do what I said in my last post, but drop it as much as I can. I'm not so much worried about the COG, as I am about landing on my lid and messing up my fan. LOL.

Anyway....








BTW, that's a 1/4" thick piece of aluminum between the cap bank and the Quark. It is bolted to the 1/8" aluminum plate that is serving as the center bulk top plate. I added the fan because it was just sitting there and it wasn't much to pop an extra couple of 3mm holes to mount it.

Careful with that ferite core that sits on the power leads..

Serum, can you elaborate? What should I be taking care not to do?

Oh, are you talking about it possibly shorting out on the motor leads? If so, I'm going to go ahead and put a piece of shrink wrap on it. Thanks for bringing that to my attention. I hadn't even thought about it.

That looks stellar man, I love what you are doing with these cap banks! I should have got you to make me one when you shipped it out. :027:

If I can't find anything to make a solid bank like that, I might just use shrink wrap, with that many caps, they shouldn't get hot.

IMO, I don't think that fan is doing anything on there, it might be better if you take it off and let air flow cool it, it might just be hindering it?

Anyways, I was looking at my burnt quark, and confirmed that the leads on the caps were vaporized.... some how? Check it out, I don't know if you can see it or not very well.

Yep, I see that alright. I fell hungry looking at that.... toast for lunch I reckon. There must have been one hell of a surge/short/whatever for the leads to melt down like that.

As for the cap-bank AAngel, neat is only a word. You wouldnt know there were any on there if you hadnt said, just a mysterious block piggybacked to the esc. Nice work.

that cap bank looks great. That fan is too big for my taste, but it's neat how how u attached it. I would of used a couple of smaller fans instead, but looking at your setup, it seems that you don't even need the fan.

Ignore my post Aangel; i didn't looked close enough, just make sure the wires don't touch eachother.. (with your rep, you know..) for guys like you they invented plasti-dip..

[zeropointbug]

Yeah, unless they were both bad caps and they shorted internally, which blew the leads from the massive currents they would have got from the battery.

Wait, I just thought of this... I could use my extra Quark case and make that into a cap bank! :027: What do you think?

AAngel dipped in plasti-dip, lol

Looks almost like both caps developed an internal short. :032:

Yeah, if wires are vaporized that sure sounds like an internal short..

I thought you had cut them off, but if this is how they looked, i think you really pissed them off..

OK guys, I'm going to start crying if you don't stop picking on me. LOL.

I think that the old quark case would make a stellar cap bank. It'll look really cool. As for the blown caps, they (S&T) did tell me that they had a run of bad caps. On my last Quark, it was the caps that went first.

Asfor the fan, like I said, it was there and I already that mount clamped in the drill press, so I made a provision for it. It moves a lot of air. I'm going to try running it on the track with the fan. If it doesn't get broken, I'll keep it. If it does, I'll take it off. It may not directly affect the cooling of the esc, but it does keep the air under the body moving around.

BTW, have either of you guys gotten your caps yet? I checked and they were mailed out on May 30.

Quark case as a cap bank- sounds sweet. If you didnt fill it with thermal epoxy goo completely you could also stash a ubec in there to get it out the way.
