Quark fried, blown capacitor...

It seems that some MMs fare better with the Neu motors than others do. I haven't heard from the guys at S&T. They got my Quark last Wednesday, but haven't heard anything from them; and I sent my Compro back to the Czech Rep a few weeks ago, but I'm not holding my breath on that either.

If I get a Neu, I'm going to have to run it on a MM. I have one particular MM that seems to out perform all of the others. It handles 5S like a charm and seems to tolerate more gearing than the other four that I have. I'm hoping that this particular unit will treat me right.

That sucks that you have two controllers go on you like that. I am itching to get mine back, BL power is ADDDDIIICCCTIVE! :018:

I am going on a trip for a couple days AAngel, let me know how much the shipping was? :dft009:

I know about brushless being addictive. I see my MM/9XL setup as being mild. I call it a "track setup." I was out at the track today and everyone kept talking about how fast it is. They just have no idea.

I was tempted to drop the 5S pack in it, but thought better of it. I'm already meeting with a tad bit of resistance from those who just might be intimidated. I hate to say it, but there are some who buy the edge with super fast engines, rather than practice. If they knew that all I had to do to keep up with a faster crowd was to change battery packs, I don't know what they'd say.

I really do love my brushless. I can't wait to get on my CRT .5 project. I'm going to run it in 1/10 scale electric truck class. They can't say anything about that, for now. I'm sure that when they see that little truck handling turns and taking jumps like an 1/8 scale truggy, some will find a reason to complain. Then on the other hand, I may just get a bunch of questions on how they could build their own. That's what I'd prefer.

Are they going to let you run 4 wheel drive in electric truck class? My local hobby shop wouldn't let me run my HPI MT2 conversion in the electric truck class because it is 4 wheel drive. They would if I took out front driveshaft, but that would suck. I really think 4 wheel drive is a must with brushless!

That seems silly, having a truck class and not being able to use 4wd. Aren't trucks ment to be 4wd?.....

1:1 Stadium trucks race in 4wd and 2wd classes.

[suicideneil]

Bah, far too many classes for my liking- just chuck 'em all in an arena, & whoevers still moving at the end is the winner. Oh wait thats robotwars.... in rc racing are stadium trucks 2 or 4wd, or both? If bdebde wasnt allowed a BL 4wd in a 2wd race, fair enough. But if it was because he was running 4wd BL and that might give him an advantage over the 4wd nitros- thats unfair.

[bdebde]

All 1/10th stadium trucks used for racing are 2 wheel drive, even nitro.

[suicideneil]

Ah, I see. I take it the HPI MT2 isnt a staduim truck as such then... that would be why they wanted you to take front drive shaft out, to level the playng field. Bah....

Cartwheels- got my caps today, they do look very good quality so should hopefully do some good. Im assuming guys that using the low esr 330uf 25v jobbies will be fine in conjunction with the big 2700uf cap that is standard on the HVMaxx? If you dont here from me again you'll know it didnt go well....

I run in a small club. They'll likely let me run at least the first couple of races, until I get used to it. They won't say anything until I start winning.

Does anyone know what the usual running temp is for a Quark Monster Pro?

[zeropointbug]

BrianG, have you recieved your caps yet? Let us know how they work for you?! :027:

[BrianG]

Yeah, I received them about a week ago, but haven't had a chance to see what I can do with them. I'm in the middle of redoing the Jato layout to use lipos and so it has more weight in the rear. Maybe I'll throw a couple of caps on that, even though it ran fine before...

[suicideneil]

Well, I got my caps from Cartwheels and decided to add 4 to the HvMaxx. I could have added more, but 4 is a nice number, and I want to leave some for future projects, when I get a Quark/MMM/Velineon4/5s??? even. I was planning on running it today but the weather was a gainst me, typical. Next week hopefully I will get the chance to see if it made any difference- I had it up on the shoe box and gave it a quick test = everything works like it should so I didnt blow it up at least.



I used some regular epoxy to keep the caps together & insulate the exposed leads, then wrapped some electrical tape around the bases of the caps to be certain. Removed the fan from the esc but left its plastic grey mount, which the cap assembly got ziptied to. Also shortend the cap power wires by an inch or so- very neat I reckon....

OK, I was running my Quark yesterday and I got the same symtoms as ZPB. No torque. I opened the case and the internal caps were puffed. Since I did the "mod" I'm going to have to remove the slab from the case and try to replace the internal caps. I may also take this opportunity to "extend" the case to allow for more caps and possibly put 5.5mm sockets on the pcb so that I can remove the power leads should I need to...or is adding the sockets a bad idea?

Oh, will the blown internal caps cause the esc to act the way it is, or did I blow something else. I was trying to get my quark to work without thermalling, so I was running without the "cap bank." I was running it easy. 4S, 14/46 on a 9XL and taking it easy around the track.

I've gotta say, I haven't been impresses with the Monster Pro at all.
