Quark fried, blown capacitor...

[zeropointbug]

It's his Quark.... :030: :027:

Oh, let the walls of Rome fall just so AAngel can have his Quark work this time. :005:

I'm telling you now, install those caps on it! I am warning you...

[suicideneil]

£10 says it blows up on the first run....

Nah, give it a check over for any loose wires/connections, plug it in and give it some welly around a carpark. If its going to blow up then so be it, but if it doesnt, then your luck has taken a turn for the better.

[zeropointbug]

You're on, 10 sterling

You guys are killing me. LOL

I got it, wired up 6 caps, and rigged everything up. I dogged it out a bit and didn't have a thermal and the heat on the case/sink indicated that the thermal pad is working for now. All I need now is my Neu back.

[zeropointbug]

Soo, you missed one part of the story. How did it perform? Which motor, your 9XL? how many cells?

It's Smoooth huh? :027:

zpb, I ran it with the 9XL on 4S lipo. Geared 14/46, it displayed plenty of power. It wasn't as torquey as with the MM, but I was running the MM on high start power and the Quark on the soft torque setting.

It is smooth and I couldn't get it to cog beyond a slight stutter every once in a while. On the other hand, I can't get it to start off at a creep either. Not like I can with the MM.

I'm going to hold any judgments until I get the Neu motor back.

[zeropointbug]

Really? I could get my truck with a 7XL geared 18/51 and stock TQ-3 to creep along at a snails pace! I could literally see the revs on the motor shaft.

What radio are you using?

You know what you should try with the Quark:

LiPo high mode and dynamic torque setting, this makes it seem crazy powerful and responsive.

Easy now.... Let him run it for a day before he blows it up again.:005:

mah, he's got the caps on there, that should save his bacon :027: :027: :007:

I don't know... Aangel has a special talent. :007:

Yeah... so do I. :005:

Hey, everyone has to be good at something. I wouldn't say that I have a talent for breaking things. I'd say that I have a talent for finding the weak points in equipment.

I'm not going to mess with the torque setting. I like it the way it is. I'm over all of the break neck torque stuff. With the 100,000 diff fluid in it, it still wheelies on demand and you have to watch it in the dirt. As for the lipo setting, I programmed it for manual and set the cutoff to 3v per cell. Even though I did this, will setting the lipo to high do anything?

I'm running a Spektrum DX2.0 radio and I can't get the truck to creep. It just kind of starts off at a roll. If you can creep around with the 7XL, it may have something to do with the gearing. I'm sure that I'm running a larger pinion than you are with the 9XL, so for every revolution of the motor, my truck should cover more distance. I'm not saying that I dislike it, it was just an observation. I need to get it out on the track and see.

The last time I was out on the track, a few people commented that they liked the way that the MM ran better than the Quark. From what I've seen so far, I'm inclined to agree. After all of this, I may still wind up with a MM/Lehner combo after all. To each his own, I suppose. If Castle releases the "fix." I'll have a couple of controllers up for sale.

The funny thing is that I ran it for a few minutes. I took a temp on the case of the Quark and got around 115F. I took a temp on the top plastic cover of the Quark and got 130F. Go figure. It didn't thermal on me, so that's good.

I need to remount my esc. Right now, I have it on a plate that double as the center diff plate and the heat of the motor is sinking from the motor mount to the esc mount, so I don't know if the heat is coming from the esc, or the motor. I'll have to turn a couple of standoffs and mount the esc plate to the standoffs and bolt them into the existing engine holes and see what the temps are like.

If this Quark takes a dump, I think I might have to take a ride over to S&T and have a talk with those guys.

Oh, I forgot to mention, they did warranty it. It was a case of no news is good news. They sent me a whole new controller. I didn't even open it up. I didn't want to take a chance on anything. I just wired up the cap bank and added the connectors.

zpb, where are you with your Quark? Have you built the cap bank yet?

[zeropointbug]

No, I have not recieved the caps or the Quark. They sent out a new Quark w/ Pro-BEC free of charge AND without me having to send in my piece of charcoal...

My gearing was 18/51 single speed tranny, it went very slow... but like you said, it doesn't matter a whole lot because these things look much better moving at speed. :027: I did have narrow nuetral band on too though, maybe that helps low speed creep?

What you said about finding the weak spot in equipment...so true. Seeing as we are still far within the rated specs of the Quark, they should easily be able to handle it. (maxx's, revo's) I can't even imagine what would happen to it if we DID run it at 125A continuous?! :002:

I am thinking I will put some 5mm plugs on the Quark and tap the input leads there with the cap bank, and solder two wires into the plug? what do you think?

My only problem with mounting the cap bank was getting it close to the pcbs. I tried soldering connectors to the pcbs and then using these connectors as junctions for everything else, from the cap bank to the power leads. What I noticed was that the weight of the connectors on the pcbs made me nervous. I just removed a spot of wire insulation from the power leads and directly soldered the wires for the cap bank there. I then ran the power for the bec and fan from the leads on the cap bank. I'll see if I can post a pic of what I did.
