Did you have the cover off and touch the internals or something? Assuming a monoblock design, 8,000w on even a 1ohm load requires around +/- 135vDC rails (270v total). That same power on 4ohms would require power rails around +/-260vDC (520v total). That can hurt!

Wow, over 1,000A on 12vDC battery power just for the 8kW amp! Must be one heck of a charging system! Makes my "old school" PPI 600w (sub) and 400w (mids/highs) system seem anemic by comparison. :smile:

Those look to be some high quality amps there. What brand? The PS section is larger than the actual amplifier section. Beefy transformers and capacitor bank...

I have no clue how the voltage stuff works LOL. The amplifiers can only accept 18 volts max. They are Class D amps around 85% efficiency. I haven't installed this amps yet. I was going to have them manufactured for me, but it seems that market for such powerful amps is not there anymore. The system that I installed and got electrocuted had 20 SLA batteries each putting out 1200CCA. Man the wire we used were 2/0GA.

I was assuming class AB (eff ~60%) in my battery current calculations, but that's still a LOT of current!

Any 12v amp over ~16w rms (and that is assuming BTL output) will require a switching power supply to boost that 12v to whatever the amp needs. BTW: BTL stands for Bridge tied Load. Anyway, let's say you have a 100W @ 4ohm mono amp. The output would need 20v rms. Convert that to peak voltage (28.3v), then add a few volts because transistors are not perfect switches (31v), multiply by two since signals go positive and negative. So, you'd need at least +31vDC and -31vDC rails, or 62vDC total. Hard to get 62vDC from 14.4vDC without a switcher. :wink: Aside from the switching PS and maybe extra output transistors for the low impedance loads for auto use, there really is no difference between a car and a home amp.

Powerful amps like that are difficult to make because of the current at 14v required, kinda like why we prefer HV setups. Plus, it's expensive. Plus, why? I mean; unless you're competing or running a mobile movie theater, why would you need that kind of power?

I was planning on competing just to showcase the product. Got tied up with my company and I'm now devoting 99% of my time to my daughter. The 99% was 100%, but she is in PA right now with her grandma so 99% it is LOL. The great thing is that she is showing signs of being a Savant.

I think I'm done waiting for a monster maxx :(

I am also really let down by castle, there over confidence will hurt them.

When despairation reaches the peaks, then....relief shall befall us..well, I hope that'll happen..:)

Al,

How are you? I was planning on moving to either Saudi Arabia or UAE, but I didn't get an answer from one of my client about a job in the UAE. I could still sell electronic components, but I would have to work 100% to really get established in either country. I was wondering if know how the school system is over there and if it might be the same in UAE? My daughter has Autism and I need to get this information before I make a decision. I'm from Brasil btw and I hate the cold weather here in New Jersey. I was looking at some houses around Dubai and they are amazing.

How are me?!!!

I thought I did interact with you befor!?!

Well, I'm fine. Thanks, for asking, hehe...

Dubai is PERFECT, but Saudi Arabia is great, too. I say Saudi Arabia comes in the second place after Dubai and..well...it needs some heavy reformations to make it as advanced as Dubai.
I think you need to find an international school for your girl, first.
As for the system, well, I really can't be of much help here...sorry, my friend..but as far as I can tell, you won't find it very different from the schools in the west...not as good, though..=(

Ok, I'll make some searches and see what I can find. Thanks Al.

I have been waiting for castle to produce the mmt control for 2 years, and if it's not ready by spring I will probibly never own one, I'll have the mgm's they will probibly be better anyway.

Right now the MGM is performing better then the MM and with some MGM's ESC offering a 200A+ controller, I gues CC will have trouble beating that.

The last thing I am going to buy is the ESC for my savage. I'm hoping this baby comes out before I'm ready to buy. After playing with a mamba max today, all i can is I want a monster mamba max in my savage.

Spoke with a CC rep. yesterday, shot the "stuff" with him for a while and asked about the MMM he said they're working feverishly and it should be out very very soon, even though the motor may not be ready yet they will still release the ESC. He stated that it's closer to coming out now than it's ever been. My guess is it'll be out by Christmas hopefully, I wouldn't put my money on it but hopefully this is some sort of indication that its coming.

HA HA, DITTO THAT!!!

I hope you're talking right.

Imagine that it is capable of 6s and plus with an incredible amp draw of 300+. Smooth operation, no thermalling and over heating. Program it via computer...what else would we ask for?

RELEASE DATE YA MORON!!!

I'm not flaming anybody here, just myself..:)

OMG that's hilarious!! :rofl:

That picture is too funny!! :lol: And I totally agree with it. I don't knwo what I would do if it is out by the holidays. :lol: I'd just be amazed.

I wouldn't buy it. Other ESC works great with what ever motor you throw at it and CC has made a fool of themselves with the software not being able to time correctly with motors 4 poles and higher.

It will have to be pretty amazing given how long its taken CC to get it built. That said, lutach is quite correct; only thing that puts me off the MGMs is the complicated programming ( I can tune a TV with my eyes closed, but those dont blow up if you get it wrong... usually ).
I'll wait and see what Traxxas & Novak have up their sleeves.

I find it easy to program my MGM, but it could be better. After you have it programmed tho it is just an amazing ESC.

I agree, my problem was that the motor shorted a phase. Its back with Mike to be sent back to MGM for repair

that is so fitting.

Not sure about what Traxxas and Novak will come up with. The VXL Emaxx will be another 14 cells, 4s setup. There is no way that Traxxas would do a 6s (2 3s in series) setup for the emaxx. It will most likely resemble the Novak HV, hopefully with a lower kv motor with a bigger rotor/can than the novak. My rustler vxl system ran way hot on 3s with stock gearing/tires, hope the traxxas emaxx system will be cooler running. Bob Novak has been running that kyosho buggy with a ctr slipper with A 48P spur and the hv system on 5s. I can see that buggy is for top speed only, can you imagine how long a 48p spur would last off road, or drag racing?!?!?!?! In any case Traxxas and Novak make stuff for the mainstream. We are not mainstream. Most here(myself included) consider a 2hp (peak) motor in a 1/8 buggy tame, and motor temps above 150f unacceptable. If a mainstream mfg brought out a 2hp system that ran under 150f it would cost a grand (or more) have about 100 sales,and I would probably pass out from shock:gasp:

I have a MMM in my CRT right now for some testing... but I can't say any more for now...

check back soon.

:lol:

GOTCHA!!!!

:na:


Just kidding... I only WISH I had one in my own two hands.... maybe someday, hee hee


Made ya look though!! :diablo:

Now that just wasn't right. After having blown up a Quark Monster Pro and a Compro 22418 in a week, I was excited for just a second there.

Dude, that's brutal. Pretty funny though. :rofl:

Cruel, cruel man. I agree that Traxxas & Novak make stuff for the mainstream, but for ease of setup/use I cant really fault the HvMaxx, it just needs to be more powerful, which the new system will be by all accounts.

Sorry guys, I didn't know the castle guy was pulling my leg. Kinda of disheartening to hear that my story is the same as many others, what in the world would take sooo long to produce an ESC, and even longer for a motor?

1. Too busy making escs for planes and boats to bother with car/truck stuff.

2. They didnt even make the motors (which makes it even worse), they just couldnt find someone to produce good enough motors in the quantity required.

I think the motor thing was just an excuse they came up with. If it was up to me, I would fire all the engineers that's doing programming and hire new ones. I have a ESC that uses the same brand of MPU and has no problem with motors that has 4 and 6 poles. Plus this little ESC has an option for A123 or the 3.6V batteries. This ESC was made by one engineer.

well, i would put money down in vegas that CC has learned a very valuable lesson to not let the cat out of the bag early anymore. most moderately big companies go through that lesson.

i'm sure we can all agree that when the MMM comes out, it'll be near-bulletproof.... after all, it'll have been tested for a long, long period of time! too bad they've lost so many sales to people who got tired of waiting and went with another esc.

It might not be bullet proof. As Patrick said in another forum he was going to just add a power board like what GriffinRU did, but it didn't work for Patrick LOL. So he said he wanted to start from scratch.

I still cant figure out why they didnt just pay (king) Arthur to design & build the MMM and save them the hassle....

Not to be cross here but I totally agree with this statement. There is nearly no proof that the product is being tested at all. I'd bet the delay is because it's been shelved. No work. No progress. The MMM is vaporware.

I think Castle could develop one if they wanted but I'm guessing it's never gotten past the Alpha development stage. Maybe they will turn their attention to it again...someday...

DM

testing and research makes no money, selling plane esc's does!

I have 6 mamba 25s and think teh world of them, but got tired of waiting. Now thats about together, I want to do andother and need another esc, so they're about to lose a 2nd sale.

Disappointing to say the least. When's novak's new HV supposed to be out?

DUDE, I was like :surprised::gasp:, then i was like :grrrrrr::cry:, now i am like:whip::slap: Just kidding
