mamba max
 
i was wondering if the mamba max could handle a bigmaxximum since it can handle the neu motors and there 4 pole too and do u guy yhink it can handle 24 cells with the ubec ?? thnax

squeeforever 09.17.2006 07:12 PM

Uh...I think double the voltage is a obvious no-no...As well as the fact that a Big Maxximum can't handle 24 cells...And not to mention, a Neu 1515 would be more powerful...

Gundam-Guy 09.17.2006 08:08 PM

im looking to run 24 cell what would u recomend?

squeeforever 09.17.2006 08:10 PM

The MGM 24/160 with a Neu 1515...

Gundam-Guy 09.18.2006 03:32 PM

is the bigmaxximum really weaker than the neu 1515??

Serum 09.18.2006 03:38 PM

I don't have got too high hopes on the bigmaxximum.

Please, can you tell me where you read about the 24 cells on the mamba-maxx?

neweuser 09.18.2006 03:38 PM

Not so much more powerful isn't what squee is saying. But the fact that the motor can't handle 24 cells at all.

Serum 09.18.2006 03:41 PM

I think the bigmaxx will survive 24 cells.

Gundam-Guy 09.18.2006 03:41 PM

in that case do u think it will work with a mamba max on 18 cellswith a ubec
?

Serum 09.18.2006 03:43 PM

No, the mamba maxx is rated for 4S lipo maxx.

neweuser 09.18.2006 03:47 PM

Just out of curiousity Serum, how long do you think the bigmaxx would survive? Seems like a lot of volts to be pushing....

Serum 09.18.2006 04:04 PM

No, why?

it's got a 2200 kv, a high efficiency and a built in fan. (and a HUGE one) that motor is build tough.

It will be a hot setup, but there is a difference between 'can't handle it' and 'usable for insane speedruns'

on 16 cells, and geared for about 75mph-80mph (overgeared?) the motor didn't got real hot..

And mine had a small fan, compared to the bigmaxxes i have seen elsewhere.

here you can see how well it's build.

neweuser 09.18.2006 04:21 PM

Ah yes. That looks strangly familiar! LOl, i see what you are saying now. you now killed my curiosity.

You know, I was just looking at those pics and realized just how nice that cooling design is. The integrated fan in the rear blowing across those fins. The fan airflow redirector also acts as a fan guard. The fins, being angled, makes sure that the air more effectively cools it. IMO, way better than a simple heatsink, or rigging some type of biscuit fan over the motor.

squeeforever 09.18.2006 05:29 PM

I just think 24 cells is a bit much...Isn't it rated for 18 cells?

Serum 09.18.2006 05:31 PM

Yeah, it is rated for 18. but 24 is doable for insane speedruns..

Brian; i've seen pictures of another bigmaxximum (black anodized) which had a way bigger fan. Twice or three times as deep with much larger fins.

Gundam-Guy 09.18.2006 05:53 PM

insane u say mahahahaha lol j/k im looking for a cheap esc for the bigmaxximum i have a Future 18.97 and a maxximum but i dont want to tear it out of my buggy. any one gaot any ideas

cemetery gates 09.18.2006 06:02 PM

i know that the BK's don't react well with 4 pole motors, so a quark 125b is probably your best bet..............

Gundam-Guy 09.18.2006 06:24 PM

hmm whould the mamba work with the maxximum? if i have to ill take the future out the buggy

captain harlock 09.18.2006 06:29 PM

One of our friends ran 6 lipo cells with his 12.97 and 9 lipo cells with the 18.97and they did not blow up. I think you can easily use 24 cells with your controller and motor.

squeeforever 09.18.2006 08:46 PM

Captain, that isn't wise at ALL...I woul say put the Mamba on the buggy with 4S and the Maxximum and get a Big Maxximum for the 18.97 if you really want a BIg Maxx...

BrianG 09.18.2006 10:02 PM

I wouldn't do that either. For one thing, the caps on there are only rated 25v. Manufacturers tend to spec in a safety zone, but at 24 cells (~29v), that is really pushing it! At the very least, its life will be shortened.

I know the MM is relatively inexpensive and it's tempting to use it where otherwise you'd have to use a costly ESC, but there are limits.

captain harlock 09.19.2006 06:47 AM

No, I meant that for the Schulze controllers.
And besides, we're bashers- I'm the soft type- where I dont push my escs and motors so hard.

I actually said what I said for our friend to use his 18.97 with the BigMaxx and feed it with the 28.8 volts he's planning to use.

I do have plans to run 8s through my 18.149 controller and see if it can survive the extra voltage.

Mike did told me once that he had overcelled some of his Schulze controllers without any declining or blowing up.

Gundam-Guy 09.19.2006 02:40 PM

so the mamba will work fine with my Maxximum on 12 cells right?

aqwut 09.19.2006 05:45 PM

hey.. if it works for your 18.149.. let me know man... cuz I just sent my 18.129 back for warranty again.. (3rd time)

I would think so... with good batteries and proper gearing. I would run a ubec just to be safe with a big motor setup.

captain harlock 09.19.2006 11:13 PM

Okay, Aqwut. I'll tell you once I try it.

Gundam-Guy 10.07.2006 10:24 PM

what is the wattage on the 1515
