Very disappointed
 

Ok, so after the programming. I ran the Quark 125b/1930 10t. It runs waaaay tooo hot, it reminds me of the hv maxx. run two min, stall, run two min, stall all because of this heat issues. I have a huge fan on this thing and even the motor wires are heating up. never had that prob with my 9920 even! I figure heat sinks would be ok, then a fan maybe two? My gearing is 12/51, that's pretty low already, i have too much torque as it is. anywho, just thought i would put that out there. IMO, this is not the best esc out there. sorry guys!:035:

Wow. Sorry to hear about your misfortune! I can't understand what the problem would be, especially since you added a heatsink and fans! Maybe you got a bum ESC?

I don't have the heat sink yet, but i have a 40mm fan! thing is huge! I think heat sinks would help, but i don't think for long!
How long can you run yours before it stalls or thermals? I mean, even my wires eventually get warm! Honestly, i think the esc is fine, it runs butter smooth, that part i like, this thing heats up like it's on stove! just like my Novak HV maxx used to do.

Mine only got to about 140ish. I didn't like that and now it sits at right around 125F. It never thermals. Of course, I haven't run it while it was 100F outside, so I'm sure that will make a difference.

Are you sure you don't have some binding or resistence in your truck? Sorry if it has been said before, but if nothing else helps, its in the truck, i have learned this the hard way before.

Since he was running fine with his 9920, I doubt it, but it's possible I suppose. Even so, that low gearing should compensate for all but bad drivetrain drag!

My drive train is great! My 10xl/9920 only got hot when i used my 20T pinion, my 18T pinion was great! But my drive train has no binding at all. I spent two weeks adjusting it over and over. When i did my UE diffs, i made sure! trust me a couple hundred dollars in diffs alone, and the the UE cvd's, all that, i made sure. with the quark, i checked a triple checked all my connections. if i doubted them, i redid them using 3 sets of deans! It's the controller, my motor is great! temps are real low, lower than my 10xl even!
BrainG - so you can run consistantly? i just bashed around lightly and it thermalled! I don't see how anyone can run Lipo with these at all!

I don't run Lipo (yet). Until I get some, I am running 14 cells on a 10XL. The Revo is quite light at around 9 pounds.

there it is. i run a emaxx on 16 cells 1930/10T, fast as hell with the 12T pinion, faster than my 10xl/9920. but my truck is about 11lbs tops, if that even. I don't get it though, my motor is cool as hell, my esc is hot enough to cook an egg on it!
Are you going to the bash?

That weight difference shouldn't mean that much - 11 pounds isn't that heavy. BTW: I'm running 40T spur/ 15T pinion with stock Revo tranny locked in 2nd. The weight I quoted was with a lipo pack I've been eyeing. With 14 GP cells, it's more like 10ish pounds.

According to Batfish's "Is my motor too hot" sticky, hot ESC, cool motor means overgeared, but you said you are undergeared if anything. That's odd. What are your battery temps like? If JUST the ESC gets that hot, there may be something wrong with it.

No, I can't make it to the bash. I'll just have to sit here and mope. It would've been cool to meet the people you talk to on here. There should be a picture thread where people can post pics of themselves. But I digress...

so is that how every one is running the quark...is on these really light trucks....so it seems like if you have a semi heavy truck, the quark will not work...that really sucks ...and I don't think he has any binding issues......I think the quark will not work with a emaxx very well...good choice on the motor though....glad you like it man.,...

To improve torque/acceleration and decrease temperatures, you'd go to lower gearing, but like brian said...your pretty low as is....

Maybe you could try a little higher?? It seems to low of gearing with the UE diffs. Seems like it should be like a 14T.

yeah, i'm runnin 12t/51t, my batts are way cool too. just my esc! i bought the 12020 though, i'm not going thru this again like i did with the HV Maxx. It's the whole reason i came here! My 9920/10xl has been very good! I love the motor Leroy sold me too. But i'm selling the Quark after two 1/2 runs on it. the bash is coming soon and i want to be ready. And it seems nothing is going to fix this heat issue with these. Anywho, i'm done with it, had it for 3 days! :mad:1:mad:1:mad:1:mad:1:mad:1:mad:1:mad:1:mad:1:m ad:1

Here's a stupid question. Are you using a ubec with the Quark? The Quark bec will overheat if it is used with 16 cells.

Is it the 120amp warrior you're getting? I think the warriors are great,well the 9920 is so i assume the 120 is aswell.My micro sucked big time though(so did Leroy's),still haven't had it repaired 'cause i just don't want it so i'm not going to spend more on it.
MGM and Schulze for me all the way.

I believe he followed the instructions and pulled the red wire from the servo plug on the end, and he was running a on/off switch on his UBEC, along with the on/off switch with the quark. I can understend how he is upset....he spent about a 1hr or so getting it to program right...then he runs it and it starts this on/off stuff after only 2 min. (thermaling)... he can drop 2 more teeth, but I don't think that will solve anything for him......and if he goes up then it more than likely will overheat more. I'm curious how you guys are running the quarks in the revo's......is it because they are a lighter vehicle. or what......I feel for ya man...

I've had 2 micro's....one 1895 from back in 2001...had it for 4 1/2 years...ran realiable as heck...no issues ever.....then poof....sent 123 amps on 12 cells thru the controller....sent it to BK..they replaced it with a 2095...and that's what I'm running now. I've had it for a year now and have had no issues to date also. And I've ran 16 cells on it with ease also....So since he's going to a 12020 he should be fine...I've also have the program plug and can help him tweek the controller..

Yes, i am using the ubec. Pulled the red wire too. I have a 9920, and i know many have had probs with them as well. But mine runs great! I have never had an issue unless I over geared it, say like putting a 20T pinion on there, But with the 18T, my controller doesn't get hot, motor runs a tad warm but that's it, runs great! And i have beat the piss out of it!

I ran that motor on a 7020 neweuser. It made the 7020 hot with that gearing on a 13 lb emaxx. I was running rd logic spikes to with ue diffs. Only ran 12 to 14 cells. If didn't run it to hard I could play until the batteries was dead. Make sure your screws are not to long.

Are you talking about the 10xl? Or the 1930/10t? I never ran the 1930 on the 9920. But i will be running the 1930 on the 12020, IMO, i think that'll be a good set up. with a 16T, I should be close to 40,000 RPM's on the 1930.

never owned a 10xl. I was talking about 1930.

I realized that now! LOL, I'm a slow reader! check your PM CHC!
Gustav - yes the 12020 120 amp....shouldn't be much different than the 9920.

Are the newer MGM's any good? Out of all the 1/8 scale ESC's that I've ever had the MGM cube design ran the coolest. It just had rough software, but by far has been the coolest running ESC. I'm finding that out after buying other controllers.

When they come back in stock these are the latest software version.They've been sent away for the update which should solve the slight problem they have with the throttle input while coasting,basically if you're coasting and you blip the throttle lightly they brake momentarily.Basically it tries to bring to motor down to the level of the low throttle imput.

If the update has solved this then they'll be a very smooth esc and in my opinion the best available.Mine is otherwise very smooth(with the drag brake off and the freewheel on)They are a very good quality unit,and mine has been robust.i had it to 200F(my fault-no ventilation and 3000 watts)and it shrugged it off.It reduced the rpm as it should and then after letting it cool it was good to go.

They have suffered from software niggles but these are getting/have been solved and you can send them in for free updates.The LVC is the best since it's manually set for cell count so you can trust it, and can be set to slow reduce rpm or hard cut off.

I think all things considered they're the best choice.The schulzes are butter smooth,incredibly so with a 19 series, but have no LVC(they have but it's too low) and customer service is non existant by all accounts.And the price.

I'm going to have my 16024 updated and i'll probably buy a second one aswell.
I'd jump on the updated ones when they come back in if you're after a new esc.

My Quark 125B runs fine.

If I run 18 cells with 10XL on my lightning (5.2KG rtr), it doesnt even heat up in the slightest.

Might be a problem with it.

That's a good thought,it would be worth having it checked out to see if it has a problem before you give up on it.

I don't think there's any esc that could run cool with the weather over here this week.100F!,thank God for aircon.

I was wondering if it is running on all the fets.
Don't worry gustav it is 100f here as well. the humidity is sucking to. 110 heat index.
I haven't got a chance to test mine out in the heat. On 90 degree day it got 120. I think it should get 130 on 100 day.

That's very cool considering the ambient temperature,what motor/batteries/truck is that with? Is it a really low amp setup?

Man, it must be 100f everywhere cause it's a least that hot here too! I'll pretty much only run my cars first thing in the morning or nothing. Even if the cars can stand it I can't!

Well, the Quark is going to Mike today! He said he would send it to the manfacturer as they are pretty good about those things. If it's ok, i still will consider selling it though...

Once you try it...You won't sell it.

I have tried it. It was smooth as butter, it was almost like it was sensored! But the temps were outrageous! Hoping Mike can do me good on this one! It's the only thing i have had issues with. But like i said, that's electronics! Mike said that Quark is very good about this stuff, so i'm crossing my fingers!

If it is messed up and the new one don't have heating issues.
Are you still going to sell it or keep it.
I like the quark. It is great like you said. I don't think I have got mine to cogg yet. May have to try harder.
