Quark fried, blown capacitor...

I went ahead and bought the lot of 200 35v 330uF caps. The larger caps were just too large in my opinion. I think it's going to be easier to mount the shorter ones. I'm going to be laying my Quark down flat and not on it's side, so it should be pretty easy to mount two to four caps. I hope this helps with something.

If anyone needs some, I'd be willing. The downside is that the best way to ship these would be in a priority mail box and that's almost $5. The caps themselves cost me a whopping .17 each.

Hmmm, let us know when you get them in. I would be interested in getting 30 of them for ~$5, and $5 shipping.

Also, in the previous post, I meant PayPal account... not eBay account.

Aangel: Like I said before; if you are interested in selling some, let me know (PM). I'll buy up to 10-15 from you. $5 shipping + ~$3 isn't bad...

OK guys, I just got off of the phone with the guys at Quark. Get this, they told me that running the Quark Monster Pro in my Muggy conversion is going to be running the esc on the ragged edge. All of their testing is on around 9lb truggies, which is the max that they recommend. The guy that I spoke to did in fact say that the Monster Pro is a 1/10 scale esc, and any running in 1/8 scale conversions has been for testing purposes. It looks like I was doing all of that ragging on the MM controllers for nothing. What I needed was a lighter truck. That leaves me SOL with my Muggy.

He also told me that he definitely recommends the addition of more caps. His words were, "the more the merrier." They are just recommending the Novak high voltage caps because they are readily available. It appears that the caps will fry if over worked and it's pretty easy to do in an 1/8 scale conversion.

I was also told that the Quarks do better with four pole motors as opposed to two pole motors. The reason being that the four polers like the timing at which the Quark runs better than the two polers do. He also recommended the use of the 2.5D for 1/8 scale truck applications; and they are running maxamps 8Ah packs for their testing.

It looks like getting those caps was a good idea. I'm going to add as many as I can.

BTW, they are working on a new esc. Presumably the Plasma. He said that it is also a 1/10 scale esc, but they are taking measures to keep it cool. It's funny, because he also recommended the use of an RC Monster heatsink.

OK, just wanted to share the info.

OK, I don't want to clog up the thread with this cap crap. LOL.

I am going to keep a handful for myself. I'm going to add them to everything. I'll probably keep 50 or so, so that's 150 I'll let go. I'm going to do Priority mail because I have the boxes and they are free and will make it easy to pack them up, so if you want some, PM me with how many you want.

First come, first served.

I have to add, the guy at Quark was really forthcoming with the information. What was great is that he'd been there and done that, so he knew where I was coming from. I think that they are going to be a great company to deal with. I just hope that I don't blow up my Quark on the first day that I get it.

I think I would like 20 caps (if they're that cheap, why not).

Do you happen to know/remember the name of the guy you talked to at Quark?

[zeropointbug]

"the more the merrier" hmmm, sounds like Frank! :005:

Yes, that's exactly what they told me AAngel. But for us folk, we don't buy 'regular' old caps do we! :017: :027:

Maybe, just to let other ppl buy from you, I will take 20 caps then, instead of 30.

I wouldn't mind 10 or 15 of them either. That price sounds like a bargain to me. I have a few Quarks running and anything I can do to keep them running sounds like a good idea to me.

So you just solder these onto the battery wire right where it comes out from side of the quark? Anything else special that would need to be done?

OK, with Brian, jhautz, MetalMan, and zeropointbug, I have one more lot to get rid of. Please understand, I'm not in the cap selling business. LOL. I broke them up into lots of 30. That way, the shipping is about equal to the cost of the caps.

[MetalMan]

My payment for a lot of 30 is in :D. It should be interesting to see what a few of these can do to help a Mamba Max...

MM, I was just PMing jhautz about that. I just need to figure out where to put them. I wonder if adding four of these to the MM will allow us to run without a fan. I hate fans.

MM: Now, just because you add a couple caps doesn't mean you can run 10s and 200A! ;)

I'm probably going to add two of them right where the battery wires are soldered to the PCB.

That sure would be nice... But right now the brand new MM in my Revo is thermalling even with a fan. Granted, it is overgeared and I was running in grass with Badlands, with the 7XL and 5s2p A123.

I'm not that ambitious ;).

It's funny (not) but there seems to be a lot of variation from MM to MM with regard to what they can handle. Some will do 5S, some won't. I have one particular MM that I can run all day long on 4S with the 7XL in a truck and not have any problems with thermalling. It may not be a QC issue, but all MMs are definitely not created equal.

[jhautz]

where do you solder these caps? I was wondering if they could be put in near the plug end of the power wires, or do they need to be as close to the board as possible, or doesnt it matter?

I'm assuming positive lead to positive wire and negative to negative. That brings another question... How do you know which lead is positive? If I remember from way back in high school electronics class on capacitors the positive lead is a bit longer than the negative, or are they marked somehow?
