MMM Specs?
 

Hi, i've try a search on the MMM Castle Homepage (and on this forum) but i was not able to view the MMM specs about Ampere (continuos and pike) and Bec.
I've seen a phrase like this: "continuos=more than you can handle", but that is not information, that is an advertise joke. Funny but not serious.
Moreover there is not the BEC specification (How many volt and Ampere?).

This has come up a few times, check out Patricks responses:

Looky there :D

good point, but thats a little useless in that its no good for comparing to other manufacturers apparently inflated specs (I have no idea how to test this kind of claim, I admit I trust what patrick has to say though)

Thanks for the links; i've read both of them.
However i'm a potential buyer and in my stupidity i buy for comparison and if i read: "continuous=more than you can handle" i can't take it seriously.

In my little little opinion, If Patrick 's goal is to be more serious than other competitors the result is the opposite.

I don't think its meant to be a joke, I've never heard of a Mamba Monster dying due to overcurrent, or even thermalling or running hot for that matter. There have been a few that burnt up, but I suspect those failures were due to component defects, as the ones I've seen were in pretty tame setups.

edit: OK I just read about one thermalling, still, it was setup to put out a lot more power than is controllable :)

Well it's better than the Novak ESCs that say they can handle 540 Amps per phase - which like PDC said - is just BS.

I ran a Novak setup in a 1/10 on-road electric for a while and it would suck down a TrackPower 2S 4900 gold bar lipo pack in 5 minutes (~12C avg) and I would generally get at least one thermal along the way even with the fan on it.

I have only been able to thermal a MM (not even a MMM) one time when I had a temporary setup in a 1/8 buggy with a Hacker 8L (~3000 kv) on 4S. It was just too small a motor for the application.

I actually think it's a shame that Caste and pdc are put in this predicament, ya know.... They have a choice of putting an over rating on there product to be able to mass market it, put a real world rating on it and risk joining the ranks of MGM and others in a niche market with lower sales, or just saying beat the cr@p out of it and will fix it if you break it.

I think Castle should use this whole overrating products thing in their marketing. They could provide a real-world rating, and then a rating using the methods other companies use. Yeah, it would be tongue-in-cheek.

Or, rate it using real-world specs, but also specify the number and part number of the FETs used. Most people will have no idea what it means, but the people that do will look them up and find out how good they are. After a while, ESCs built with 36 x D4RRT5 FETs will be known as the creme of the crop. (Yes, that's a fictitious part number.) Kinda like how CD players used to state how they use "Burr-Brown D/A converters". Not many know what the heck that means, but all the good stuff used them, so it must be good. :smile:

Or they could use a rating system like AMD CPUs used to (still do maybe, I havent been into that scene for a while). How 1.83Ghz AthlonXP would be marketed as a '2500+' to compete with intel, back when all anyone cared about was the megahurtage :P

I'm such a freakin geek (and willing to admit it :tongue:) my brain just shifted from RC to A/V and started purring thinking about the single bit burr-brown da converters.

Kinda like how when mp3s just came out the Frauhoffer (sp?) MP3 codec was supposed to be one of the best quality codec for encoding MP3s.

Sorry - just digressed big time there - but I totally agree that if you market something big "Now NEW and IMPROVED with high-tech MA987 FETs" (or whatever) people don't even know what your talking about but will just buy into the hype.

Kind of like in the movie Idiocracy "Its got electrolytes!" "What do they do?" "I don't know but it's what plants want"

Well, that would work too, but I was thinking more along the lines of if CC specified details about the FETs used, it would become the standard by which other ESCs are judged. If the average "Joe Sixpack" saw a CC 100A ESC with 36 X MA987s, and then a no-name ESC with 18 X MA987s rated for the same 100A, Joe could assume right there that the no-name brand is not going to do as well. Not so much an absolute knowledge of the device specs, but the relative differences between ESCs.

Well if you look at the resistance of the fets, at least you can compare to other escs.

e.g. The Mamba Monster is .0003 ohms, and them Mamba Max is also .0003 ohms (doesn't have that spec on the site anymore but that's what I remembered it to be)

The novak hv maxx is .0013 ohms and the GTB is is .0004 ohms.

Can't go by the rdson value alone though. That's like saying just the number of cyclinders determines what engine is the best.
