How much are you willing to pay for New Quark Monster ESC if they make one.
 

I visited Quark to get my ESC and UBEC repaired today.
They looked a little tired, I asked them some questions about ESCs.
My first question was if they saw Mamba Monster Maxx, and if did, what they thought of it. But they seemed not to be too interested in it. But the answer was yes. And my last question to them was if they are thinking about making a Super ultra HV ESC for electric monster truck. The answer was they haven't thought of it yet, but they knew monster trucks are a big thing in the USA. And they said they will seriously think about it if customers want it. So I told them that since sky-technology is a company that sells a lot overseas, they should be aware of the fact that Mamba Monster Maxx is coming out next month, and they will lose a lot of customers. So I told the guy that Quark had better come out with a super HV monter ESC that is more reliable and capable and as cheap as Mamba to compete in the US and the world.
Anyway, the service was great. The customer service person that I talked to was very kind. I want to help them out by gathering some information. So please write your opinion. And please some functions and technologies that you want to see in it.

So how much are you willing to pay for a Quark ESC that exceeds MGM and MMM's capabilities?

Sounds like there's not much of a chance that they'll make an HV ESC. And if they're not really interested, how good could it be. Their stuff is over-hyped and over-priced.

The Quarks' pricing is a bit inflated for what you get IMO. They do have butter smooth controllers though and they run pretty much any type of motor. I also like the way the startup algorithm works vs the MM. But for more than twice the price as a MM, I dunno...

Brian, have you tried the NEW firmware for the Mamba Max yet?

It's really a different controller now IMO.

id pay $300-$350.... :yes: i personally love quarks. had a 65 in my rustler on 3s and a 80 in a oooold emaxx on 5s. it worked great, vitrually no heat issues in the maxx and was flat out cold in the rustler. motors were a 8s in the rustler and a 10xl in the emaxx.

Not yet. I know they made changes for the Neu motors, but wouldn't think they would change the starting algorithm... I'll have to check it out.

For a quark ESC only, that is comparable to the MMM, I would pay $220-$260

Because the MMM is going to be around $300 for the ESC and Motor.

I believe they have changed the starting algorithm. I tried it before with a 12 pole outrunner setup. All it wanted to do was cog, and act confused on directional control, before it thermally shut down.

Now I'm running my E maxx using an AXI 2926/8 12 turn outrunner. I do have a fan on the MM and a CC BEC being fed by 4S Lipo, 5000mah 20C.

I can't make it thermal, the ESC runs cool. I can't MAKE it cog either. It has great low speed driveability. Even on the very first step of the throttle at the controller.

I pulled a Monster Pro 125 amp to give this a try. I think I'll just leave the MM in there. :yes:

It is every bit as smooth now, perhaps even a little bit better.

If you have one laying around, try it and see.

I treat all firmware updates just like PC BIOS updates: Unless there is an added feature I want or fixes something I specifically have an issue with, I don't generally change.

None of my MM's were having issues, so I never thought to change it. I guess I now have an excuse to do so. :smile:

Hey BrianG, the firmware is for real. even with stock castle motors you can see and feel a difference. Like Sike said, its like another esc altogether

sorry about castle comment on a Quark thread, but backing up sike.

On the topic of a SHV quark, that'd be intresting. But my experience, is 5s is too much for racing. Bashing however, I'd get one

Isn't that 100% dependent on motor KV ? If the motor KV is low enough to get into a good motor RPM range with 5s or 6s, then you are MUCH more efficient than similar speeds on a 4s setup.

I'm not sure If i'd be interested in an HV quark or not. My experience with the 125b's has been less than favorable. My MM is just about as nice a performer, at 1/2 the size, and 1/2 the cost. I love my smaller quarks, but the 125b is just a disappointment to me. I suppose you guys could try it out first, and if it beats out the MGM and MMM then I might give it a shot, lol.


J.

I think that Quark has potential to make a very nice esc. The 125B just missed the mark with the heat issues due to an improper case design. Other than that the issues with it were minor IMO and it was an all around good performing esc. As a matter of fact, if the updated version of their escs are as good as the 125B, but with the heat problem addressed I would be very happy to buy it for similar prices as I paid for my 125Bs.

I have the MM with updated software and yes it is a WORLD of difference from the old MM software, but I still dont think its as smooth and controlable as the Quarks. Both on the thottle control and the braking I think my quark is still superior to my MM.

Now to this point I havent found a need to a Super HV ESC, but I can see it comming. I think if anyone could make one that performed fairly well for less than $300 and supported it it would be a good seller.

That's true, but My 1700kv 1515/2.5 blows the tires off on my track on 5s. I know KV determines speed, it also determines torque and power. The higher the overall power and efficiency, the motor likely there will be at least traction problems, broken parts at most

I don't think the 1515 2.5D on 5s is too much for the track. With the gearing I usually use (46/12) it has less top end than almost all the other 4s truggies I race against. Even when I did some practice laps on 6s with it and 46/13 gearing it was very fast, but still controllable. And how much you spin the wheels just depends on how you drive.

I will by Quark, just because it is different for around half the price of 125B, because IC's now days are getting cheaper and they already good for CE and RoHS.

As for design flaws, I can pass them couple thoughts if they contact. But in general I am not happy with pcb layout they have, from heat transfer stand point. Enclosure (case) can be improved but pcb is the culprit. Also, make it water proof, so simple with silicon wires...

When I first saw the 125B, I was a little freaked out as the positive and negative power wires came out ot the same place. When it burned and I opened the case to see what had gone wrong, you could see that the problem might have started there. I like ESC that places the power wires at the corners. Like the ones I'm having made and the one Artur made. If my controllers gets done soon, it will be the first of it's kind just for cars. That would be too funny considering that the big players all have HV, but they are for aircraft. I have no clue why we haven't seen a HV controller for cars yet. To me all this companies are too greedy and only thinking about what the returns might be. Off topic: A lot of people are pissed of at a few Asian companies for pricing the products right (In my opinion). You can buy hard cased 3200mAh 7.4v lipo for $34.99 (used to be $49 which still is cheap). They use the same concept I use and when my controllers gets done, I will also use the same concept.

Hi, I saw the video footage of your daughter. She is lovely, and you must be very proud of her.

I think you have a lot of things to say about Quark Monster Pro 125B. Can I ask you to be more specific about the strengths and weaknesses about that particular ESC? I personally agree with you on that ESC having the + and - power wires coming out of the same place. And I think Quark should have made the case differently, so that it gets cooled more easily. Please let share your thoughts with me. Thank you ^^:yipi:

The price is too much. So how much do you think it should be? And what improvements you want to see in it?

Hi, Griffin.
I think you are right on the price of 125B going down in the future. Even though I didn't hear a clear answer to my question from Sky-Tech, I think that they have been affected by Mamba Monster Maxx when I heard they said "yes, we have seen it." The company didn't have a lot of workers in the office when I visited the company. Maybe, it was due to some people going on leave after a long business trips. (They had been gone for almost 2 weeks for participating in a trade show and racing events) So the guy I talked to seemed to know a lot about the company's future plan. Anyway, if you take a look at the SSB-mk3 (mk1 and mk2) the case design is much better. And when I called them today to ask about my SSB-mk2 being fixed, the guy said that they have changed the CPU and did other upgrades for my ESC for free. If you let me know about your thoughts on possible upgrades to Monster 125B, I will let them know about it.

Thank you. ^^

Thank you. She is my life.

I'm trying to have a HV controller made. The engineer was going to do a 200A capable of 14S lipos, but he used sample boards that did not handle the AMPs. So I asked him to do a 60A, 80A and 100A. I like HV (12-14S) as it helps keep the temps down. I've talked other companies about this and they make it sound impossible to do. I'm not an angineer, but I know it's possible as I have a Schulze 40.160 (14S lipos), Actonic120 (12S lipos) controller that has car mode. The problem is that most companies want to make things smaller and smaller, but then they say hardware is not compatible. Kontronik did a fantastic job with the Jazz 55-10-32 as it has a car mode. It is small and freakish powerfull. I only hoped Kontronik would make the Power Jazz that way as well. There are very good MOSFETs out there and they need to focus more attention on them. I like the MOSFET found in my HW and I know Cyclone will have a controller with the same MOSFET. The SHV from Castle also uses them. Most people should realize that with HV you won't need 200A. You can still use 4S, 6S, 8S or 10S lipos if you want. You will be able to go out and buy a smaller capacity pack at a great price. The way some controllers are built though, you can still have a controller put out 200 or more AMPs for the bursts. Keep in mind, in order to get power from a 6S set up you will need more AMPs (22.2V x 200A=4440 assuming your batteries can put out that much AMPs), with 10S set up (37V x 120A=4440 now a good 5000mAh pack will do that), with a 12S set up (44.4V x 100A=4440 that's better) and with 14S set up (51.8V x 85.71A=4440). Now 4440W is a lot of watts. Most people are happy with 1400 to a little over 2000 watts and if you devide 2000W/44.4V you will need 45A to get it and 2000W/22.2 will bring that number up to 90A. Kontronik, Schulze and Actronic are the only companies with good HV (real HV not 22.2 volts) car ESC. I apologize for the long post, but I like HV :lol:.

Edit: Also, a lower Kv motor tends to make more torque then a higher Kv motor does and one advantage of a electric motor is, powr from torque.

I wouldn't pay anything more then the price of a mamba monster. It's just silly to pay anything more for the same electronics and packaging

I agree with you Lutach. Current market wants everything smaller, faster, more powerfull and better. Powerfull and smaller don't go well together.

Amen! I would MUCH rather have a larger ESC that runs cooler than an itty-bitty one that is thermally challenged...

Double Amen to that. If Ron and I can stuff a Schulze in our 1/8 scale trucks, anything manufacturers make will fit. You guys, I'm apoligizing again as I forgot to mention MGM and BK to the HV companies that makes a car controller.

I am using the 125b in my RC8 and I really like it. So far, no major heat problems yet, but it does get warmer than I would like after about 15-20 minutes on a track. I would buy that new ESC if it doesn't have heat problems.

Personally, I rather pay for performance. I would gladly pay a couple hundred bucks for an ESC that works flawlessly. Let me repeat... FLAWLESS. In fact, I wouldn't think twice about dropping 400-500 bucks for an esc that I know will never have heat problems, will never cog, will never have ghost in the machine problems like full braking while the car is in neutral and any other problem these manufacturers can't seem to figure out.

My only hope is that the rumored MMM will solve all these issues. I have a lot of confidence in them given that we can pretty reliably use the standard MM without too many issues, so I would hope they can make a purpose built ESC for 1/8's that doesn't have any issues.

I would add that customer service and support for me is worth at least 50% of the asking price. ONLY from what i hear about MGM (lots of help from Mike but then back to Europe), Schulze (fire and limited warrantee) and Quark (thermalling, mod hacks and ok support) has left me waiting a year for the MM.

I've burnt 3MM in the mean time (paying for 2 as they were in 8th conversions on 4s) but each time turnaround and service was great.

I am looking to buy another HV controller as a back up to my HV-110 but at this point don't know what else to get other then a HV110 again. I wish the MMM would have been an HV model, that would have eliminated my confusion. At this point I think I'm going to order the TURNIGY Sentilon 100A and 1 of the Himodel 200A controllers which both together is still cheaper then 1 HV CC controller. The Himodel says it will handle up to only 7S though, but I will try it anyhow. I just recieved my 2nd Neu motor for my E-maxx, I think this motor is more suited for high speed runs since its only 1860KV's. The 1521 1.5D should lay down some big power and only has a 95amp draw. I had a 1527 1D and the amp draw was WAY to high (200A). Just hope one of these ESC's will handle it.

what exaclty is a 'super hv esc'? :angel:
lets say it would be able to deal with 200A constant and whatever burst and up to 8-10s lipos... good heatsink bolt on.. or watercooling ready ... i guess i would easily pay up to 400$. :whistle:

Fried Quark Monster Pro 125B
 

So do you think that the positive and negative shorted this out?It does seem to have started at the power wire end.This almost toasted my truck.I am very bummed to be out 275 bucks and no reply from quark.I have run the same Neu 1515/1.5D/F 14.8v in my MM holemod.I had to almost rip the top off my Losi 8t to yank the ESC out when it fried.The power terminals melted off the ESC.

That is a familiar site :lol:.

So what are the chances Quark will replace my burnt crispy esc.

They are very good about it normally, no questions asked most of the time. I think there is a phone number on their website somewhere...

Quark sent me a new 125b monster pro free of charge.:party:thats great customer service thanks quark
