We are going to have some fun. Artur will make that thing a beast.

The search is over... well, if you concider 6s high voltage anyway.

I was checking those out a couple days ago. The 120A unit looks pretty promising. I wonder what they have in the way of reverse.

Just received the ESC...

Well it is not as good looking as known brands, but if you guys like the way it works than we can tweak it quite easy.

Kinda odd looking with TO-220 fets, I think we can replace these fets with better ones with smaller footprint. What you think, Lutach?

And I am still waiting for the second unit to arrive from ebay.

NICE

AAh, better fets. Griffin is gonna work his magic.

I like the way mine works. I just don't like how hot it gets with a 7T 380c brushless 2s A123. With the 12T hacker it runs cool with 3s A123.

If you have some superTO-220 FETs to use go for it or go completely wild with some iso's 400A plus MOSFETs. Some of those have monstours specs. If I had 1% of your skill Artur, I would do what you did with the nice looking powerboard you made. I like the DPAK MOSFETs and some ESC that uses them doen't seem to have any heat issues at all. Do your magic and keep us posted please.

I hope you guys find something soon as I need something more then 14S now :whistle:

I see that it has a car mode on the prog card, but it does not say anything about that in the description. Any other info would be nice...

To me it looks alot like a BK 120.

The car and boat mode is not active yet. Scorpion is still working on the car software and when it comes out it should be nice. I hope they the ABS (Anti-lock braking system) that I mentioned and an option for A123 type cells 2V cut-off.

I will wait with you :lol:. I know the SHV will be coming out and I will get one when and if my 1/8 scale F1 gets here.

You people do realize that 14s is starting to get into the shock hazard range right? 14s is ~60v. With my fingers, I can feel the "signal" from my 600w car amp at full tilt and that's around 50v. Of course, AC is a bit different, but pretty soon, we're gonna need a qualified electrician to certify our setups! :lol:

Yeah, but I need more power to push my MMT and new XLB project even faster. Only way to do it is more voltage.

You need 60v to push a 1/8 MT? Dare I ask what motor you are using for this?....

This is awesome though. My controllers will be able to go up to 15S, but 14S seems to be on the safe side :yes:. I've been shocked a few times and one more time wouldn't hurt :lol:.

There are plenty of choices out there.

Yes its the XTM MMT and the XLB which is the 1/7th buggy. Both are huge and have almost 17" wheelbases. I have 1521's, 1527's and motors in between. Shooting for 100mph with the buggy once its done. The truck I'm shooting for 80mph....already have some results with it on 8S and 10S which I will get the video up soon and the GPS reading :wink:
. So far 78.6 on the GPS and 78mph on the bushnell radar. Heading out to the airport to do the runs again next weekend and get some good footage.

Sheer bonkers... ness. I wish you luck though, speed is more of a challenge than almost anything else in the RC world.

Keeping them on the ground is the challenge...:lol:

I thought one of you guys might be interested in this.

I have to many of them already...hehe.

How they can claim 120A with the same number of FET (and part numbers) as Novak HV-MAXX, maybe with slightly better cooling? Which can barely handle 30A continuously without overheating.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
<o:p></o:p>
Sure we can make it better, and I think you right, Lutach, for smaller footprint D2pak-7 would be great choice. But I will do that if there would be demand, otherwise I do not need one for myself.<o:p></o:p>
<o:p></o:p>
I will mod this one with irf2204 and with better soldering and cooling and we will see how it does.

Keep us posted on how it does. The irf2204 is a nice mosfet for sure. Did you make your board work with the MM brain? I have an idea of a new ESC. It will use 120 MOSFETs total (40 per phase) and the power boards will have a small foot print, the only problem that I'm having is putting the idea into a drawing to show you how it should look. I have the Eagle program, but I have no clue how to use it :lol:.

I will,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
Haven't had a time, yet, for complete solution. And I am happy with last gen. power boards anyways, and as for high voltage MM ESC need to be studied a little bit more. While you in process of delivering high voltage version anyways, right? :)<o:p></o:p>
120 is allot, and you meant 20 per phase, H-bridge requires 2 fet's per phase. Just make sure that pcb traces can handle this...<o:p></o:p>
As for Eagle you can start from tutorial, or from examples. But at the beginners level I would recommend ExpressPCB, very simple.<o:p></o:p>
Also you can just make it in paint shop and I can do the rest or somebody else...<o:p></o:p>
Meaning we can start layout/project and you can finish/learn.<o:p></o:p>

hey Artur, have you started formulating a guess as to how much (if at all) we may be able to push the upcoming MMM? I'm just guessing that the fets used to get 25volt ability will have some overhead...

The guys that is doing my controllers told me they would be done this month, but I will only believe him when they are here. The controller I have in mind will use a total of 120 MOSFETs, so it will be total 40 per power board 20 FETs on each side. You are right on this one 20 per phase. The FETs that I'm basing this controller on comes in 30V and 60V, so a HV version can be made. I'll try to cook up a very detailed drawing to see if it'll make sense. To me it does, but to someone else it might not. I also have a crazy idea for the traces to handle all the power, but I'm not 100% sure it can be done. I'll find a way to get a drawing and best explanation out to you as soon as I can.

Let's see what it can do in stock version and then chop fan off and add 25% :)
- based on how good was their last gen. MM pcb
I hate to say, but connectors on ESC are bad idea, remember MGM..., maybe that was only on pre-production units?
For given moment why not to mold all three wires together, like a ribbon cable, you can even twist it and make it more compact...Lets patent that:diablo:

I think Patrick of CC said the esc-only model of the MMM will come with 10guage wires hard-wired to the PCB, with bullets on the ends to the motor. I prefer the sound of that really to the bullet connectors on the PCB...

Interesting link...

Up to 15S!!! and 200A

Too bad they can't keep their word. Do you know how when they took the picture of the one with the yellow shrink wrap on it? After I sent them the MOSFETs to make my 200A controller and before that they only had the one showing the components. Plus they should take the 200A out of there as they only have crappy sample boards and they can't handle the AMPs. Funny how Suppo made it seem they were the first to come out with a 200A 15S controller. They said they can't even sell 200 units, I wonder why. I told him I can get enough MOSFETs to make 1000 units, but I didn't get an answer yet. All he said he'll do is the 100A, 80A and 60A for me and not the 200A. Here is the link for my controller http://www.rc-monster.com/forum/showthread.php?t=7651.

Someone was pulling some Amps...
 

Which ESC is that based off of??

120a modellfun

Ahh that's not a bad looking ESC in stock form. I was thinking about trying one on my basher. It does have a car brake yes?? Also will it handle 4 pole motors?

Yes it does have brakes. My 5yr old was using it with a 8T feigao and was clocked at 37mph doing his speedruns with the frankenrusto. I put back his 12T little hacker as the esc runs way cooler. The ESC has a delay between a stop to going again.

Is that the brain board for the 120A car controller? I thought they were supposed to be red and the mosfet drivers were not IR brand. If they changed it that will be good as the IR has better replacement.

That is what I've got from Jammin...
I haven't opened yet freshly arrived unit from China...

That is the brain board from you 120A right? If it is it might be better then the red one I got which has a mosfet driver that seems to be impossible to find specs on.

Yes, it is from 120A ESC.

I'm still waiting for some stuff to come in (Some crazy powerful MOSFET) before I send you what I have here. All I know is that my Jazz 40 is going to rock after it's done. I hope I can get all the stuff soon.
