New traxxas castle mamba monster extreme? - RC-Monster Forums

BrianG · 11.30.2011, 06:45 PM

lol, well that ... pardon my French ... SUCKS.

Is Castle going to release the MMM to the general masses with the new FETs, or are those FETs only for the crippled MMM? Hopefully I can just pick up a newer MMM with the newer FETs and add my own cap bank on it and be good to go without the Traxxas police dictating how I should run something.

Sorry Pat, I'm not angry at you guys, I know it's a Traxxas thing...

The MMM is now shipping with the new BSC011 MOSFETs.

Cool, good to know. My wife has a Mac, and as much as I hate to even look at it, I might have to download the app just to unlock the ESC. Either that, or just sell it on ebay even if I lose out on the sale...

They look a bit alike, don't they??

Sweet. Now how would I know which ESC at my hobbyshop or anywhere else would have these new fets?

Well -- without opening it, you couldn't tell. We kinda sneaked this upgrade in without any fanfare.

We've been shipping with the new FETs for about two months. But there are still a lot of NTMFS4901 based MMM controllers out there.

How much difference between the old and new FET? Not as much as you might think, because the copper and capacitors in the MMM are the main limiting factors. The power handling difference between the old and new MMM MOSFETs is less than 5%. Add a capacitor pack (like on the Traxxas version) and the power handling goes up by about 15%.

The only thing I hate about adding caps is that stupid spark that startles me every time (even when I expect it). Is it still taboo to use a no-spark resistor on these ESCs?

We'll have a nice little fix for that in about a month. Watch the website!

NOW we're getting somewhere! It sucks replacing connectors every 10 runs from being pitted by the huge spark on every hookup. I've even toyed with adding smaller "sacrificial" connectors, but wasn't worth the effort.

I'll be watching.

I almost welded my plugs together on my Ebike and my 19 cap capacitor bank.

I've seen at Traxxas in the parking lot -- Viper ACR, Lamborghini Gallardo, Ferrari 430...

And at HPI -- Ferrari Enzo

My Nissan just doesn't compare.

Damn man. Traxxas and HPI are some ballers. Your Nissan is still a nice onroad monster though.

There are new people working at my local hobby shop and they won't let me open every ESC up, like the previous peeps did. I guess, I will have to wait a bit. What are cap values on the Castle cap bank?

Panasonic FM series, 220uF 50V, x 4

Call me stupid, but i dont understand how a pinion change cannot be done without unlocking it? Also can the traxxas radio and reciever just be changed out to bypass the lock?

Oh I would take your GT-R over anything European. Good choice Patrick!

No, you need the app ( and therefore traxxas radio equipment ) in order to unlock full speed potential- can't be done via a PC by itself.

BUT, it gives you a good excuse to buy an Iphone.

Of course you could always borrow one just to unlock it.

Go to the AT&T store, grab an iphone off the display, download the app, agree to the waiver, and unlock...

lol, no thanks. I have a personal "thing" against Apple (more or less about mediocre hardware for inflated price). My wife has a Mac because it's supposedly "easier to use" or whatever, but oddly enough she's always asking me to do some tinkering on it. And, she's actually running WinXP in VirtualBox because there are some things that *gasp* Mac can't do.
