Quark fried, blown capacitor...

jhautz, I tried both of my Spektrum radios and the MGM wouldn't program for freewheel.

I was surprised when MGM said that there was nothing wrong with my Compro. The radio is the only thing that I have to look to now. When I get the Compro back, I'll just have to try it again. If it doesn't work, I'll just dump it. Maybe I'll just send it to you to see if you can get it working. LOL

I'm just kind of hesitant to have you confirm that I am, indeed, an idiot.

That is truelly bizarre. Have you thought about trying that adaptor thing which is used to operate a plane/heli esc via pistol grip radio? Pixstick or something it was called... Also, have a good fiddle with the epa setting etc (I'll refrain from making a joke about playing with your knobs.... ah, too late).

Hey, I LIKE playing with my knobs.

Anyway, I did try turning the throttle epa up to 125%. Perhaps I should try turning it down. I don't know. All I do know is that I've been waiting for around a couple of months just to have MGM send me back what I sent them in the first place.

I had the same problem with my mgm it was like the drag brake was always on. I never figured out anything that fixed it.

Whenever I program a radio to a new ESC, I always make sure EPAs are set to 100% (no more, no less) on both the forward and reverse directions (they are seperate settings on a Spektrum). Also, set the trim to centered.

Brian, that's the same thing that I do. With the MGM, I went as far as to reset my Tx to factory default settings on everything, to make sure that I didn't miss anything. Still no go.

Do you know if MGM actually tried to run it in a vehicle, or did they simply use some type of diagnostic equipment?

I don't know about this, I managed a run in today, boy this 7XL is a handful. I forgot how powerful it is, I am wondering if the 1512/2Y would have been a better bet than that 3D? Mike said it's in Wednesday, but it's not too late just to use a different motor as he said.

I now want 7XL power or LESS, not MORE! No matter the terrain, I can wheelie at any speed! It's just too much.

My Quark thermaled today too. :mad:1 :019:

[BrianG]

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.

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.

Yeah my Quark seems to be running cooler with my 1515 2.5d compared to my 7xl so far, but the weathers not as hot here any more and I haven't gotten to use it properly at racing yet, but I still think it would be hotter with the 7xl.

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?

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]

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.
