Quark fried, blown capacitor... - Page 37 - RC-Monster Forums

lol, just stay out of the throttle as much and it'll be controllable. :) That kind of power is addicting though. I'd rather have it and just turn it down than to want it but not have it.

Just because I have an itchy trigger, and my finger just HAPPENS to be 'happy'.... :005:

That's true, I am getting better at the throttle part of things. But now when relatives or friends want to drive it, I can say 'yes', with the EPA on my radio... turn it to 35% and they are good, then watch you at 100%. :027:

My 7XL, with my eagletree, I am recording CONSISTANTLY over 130 amps, so yes I expecting the 1512 should be below 100 amp spikes. I just can't believe the amount of heat the Quark is able (why?!) to dissipate!

JHautz, have you tested out 6s lipo with the cap mod Quark yet?

Brian, I don't know what MGM did. All they said was that there wasn't anything wrong with the controller. That was a couple of weeks ago. I still haven't gotten it back. I suppose I could shoot them an email and see.

ZPB, the 1512 should pull less current than the 7XL, so don't freak out about the thermalling yet. Wait until you get the Neu in and see what happens. I think that the 3D will be a very good motor. If it does turn out to be too much, then pull a cell off of the pack. You will also be able to gear down a bit too. The Neus are supposed to be able to handle that without over heating.

Aangel; the problem with the MGM dragbrake happened with my 24160 too, i thought i was crazy and had a programming screwed up. Read the manual, i found it rather confusing to read the description, there are some contradictions in it.. like if you don't want dragbrake you don't put the option to off. something like that

suicideneil · 06.17.2007, 04:44 PM

I think thats were the newer models will be better, with the same programming ease of the MM- they have that new pc interface software.
Ah, the joys of the HvMaxx, no programming problems, because there are no programming options as such!

Serum, I tried every possible combination that I could think of. Drag brake on/off with the freewheel on/off. I could not get the Compro to freewheel.

According to MGM, they tested my Compro "extensively" and they couldn't find anything wrong with it. It looks like I'm going to be eating this one. I didn't even get the opportunity to blow it up the right way, by playing with it.

BTW, did you get your caps? I sent them a long while ago.

ZPB, my quark gets hot too. I've given up on taking temps. I've gotten to a point where the case is reading around 135F, but the area around the motor leads are always 165F or so. I haven't had any thermals, but on the other hand, I've been afraid to run the Quark really hard.

When I was having trouble with the prior units, Frank was always sure to point out that the feigao motors are really inefficient, as though he was inferring that the motor had something to do with the esc going up in smoke. I'm waiting for my Neu to get back (it's been two weeks today since I sent it off) before I really give it a workout.

To be honest, if the Lehners become available again, I'll grab me a couple of 1940s and then my Quark, Neu, and Compro are going up for sale.

I've had it with all of his crap. At least the MMs do way more than they are supposed to and I've heard very few complaints about the Lehners. I'm just having a hard time deciding between the non hi amp and the hi amp versions.

Did you try increasing your neutral range? It seamed to help mine a little but it didnt solve the problem just masked it.

06.18.2007, 08:23 PM

Yes, I did do that, but all that does is make the neutral range easier to hit. It doesn't make the freewheeling work. Besides, it still leaves the possibility of not letting off of the throttle enough to hit the neutal range.

It shouldn't be this way with a $200+ esc.

What can I say, I'm just bitter. LOL

I dont blame you, I wreck enough on my own I dont need any help from my brake happy ESC. :031:
They must have had brake issues during R&D and released it anyway.

Seems like the more expensive the controller the more problems they have, eh AAngel... :005:

06.18.2007, 11:57 PM

zpb, it sure seems that way. There is still more stuff to try though. Castle is taking its time with the MMM, but I think that it will be good when it does come out and the Tekin controllers should be interesting.

There has also been talk concerning the Kontronik motors and Mega is releasing motors for rc cars too. The future is either looking brighter or the money pitt is about to get larger.

plumslow · 06.19.2007, 08:57 PM

I have a question, many people on the forum say that they want to run 5S to get longer run time. I was looking at the batteries and cell counts. I was thinking of them as watts = V times A and a 4S 8000 mah battery and a 3S 11000 mah battery has about the same watts and both batteries would weigh about the same so where is the advantage of a higher voltage battery by using more cells. They both have the same amount of energy on tap. You would need a hotter motor for the lower voltage. What is the real advantage of the more cell packs please enlighten me.

Speaking of other motors, Great Planes (Tower hobbies brand), has a few that look decent. They look like the fiegao's but have a screwed endbell.

Hmm, they are rather intersting. The long can model is good, but only 1280kv- I wonder if they have a larger range somewhere else.:024: *begins searching...*
Edit: found their site.... no joy. Only the one xl can motor, but lots of other smaller ones.
