Mamba Monster fires.
 

Hey guy's,

I just received a disturbing call from my hobby shop mate, www.rcgarage.com , asking if I'd heard of any MMM's catching fire.

Has anyone heard of this happening??

We're thinking that it's possible with stupid people, running stupidly powerful &/or crap motors, crap batteries &/or incorrect gearing.
Any thoughts?

BTW, I ran mine today in my CRT with Neu & a maxxamps 14.8 6000mAh & it was a rocket, think I have to tone it down alot, so, those nitro's have half a chance at keeping up!!

Also, is the internal BEC adjustable to increase the output to 6V? If so, how?

Check out this topic about increasing the output on the BEC http://www.rc-monster.com/forum/showthread.php?t=11957

Thanks for that DB.

Hey, where in Aust are you?

Its certainly possible to incinerate one if you do something bad. You can do it to any controller. I have had a few controllers go up on me in the past, but not a MMM yet. I did read somewhere about one going up, but it sounds like they had a severe battery wire short that caused the problem. I wouldnt think there is any more problem with the MMM than any other controller on the market.

The only real problem I see with the Monster versus other controllers, is that the price point and relative ease of setup has potentially put a very powerful controller into the hands of morons who will not set it up properly.

I can't tell you how many threads I have already seen on the traxxas boards alone trying to use the monster with crap setups and then arguing ensues when you don't agree with them. People see to think there is some cheap way to get into brushless in monster trucks and 1/8th scale which I think is a big culprit for potential problems.

Central Qld? Too far to visit our track in Vic. :lol:

I agree Tex. I started with my BLST on the cheap side, but, after seeing my mate toast a motor & ESC I decided to go a high quality ESC & batteries. Motor's (Feigao) are cheap enough to trash.

I think I may have solved the problem of the BEC not providing enough power too.........my Spektrum Pro receiver was glitching a bit at the track, so tonight, I swapped it for one of my Spektrum Micro Pro's (brand new) & the wheels would turn on the carpet easily.

However, I've yet to try it on the grass.

The power delivery issue sounds like dirty connector pins to me. The negative and positive supply wires are paralleled on all the receiver pins. So, the only thing that would affect power delivery would be the PCB traces connecting the pins, or the pins themselves.

The glitching could also be caused by dirty receiver pins, especially the signal pin. Or, maybe the antenna wire is broken (either partially or intermittently). I had a Spektrum receiver that glitched. After I replaced the antenna wire, the glitching went away.

Thanks for that Brian, I'll check it out tomorrow.

Bedtime for me.

Say what you will. :mdr:

I may indeed be stupid but this was run with a Neu 1512/1.5/D/F and a Polyquest 25c 5000 mah 4s pack. And it was geared 11t/46t in an MBX-5.

That looks just like mine! Castle says it's probably cuz my motor (7xl) got demagged.

There's absolutely no credibility on that board. It's run by kids and it's for kids. I think we will all agree to that.

Not to mention the rules are very "fluid" there. I got 20 warning points for the word "crap" and then the same day saw several posts/threads with the same word (and worse) with no repercussions. Needless to say, I don't go there very often.

That's ok though because I get tired of the same questions over and over and over and over and over again. I feel like telling them to sell their vehicle and get a Tyco because the stupidity level of the questions shows they aren't ready for such a vehicle.

You mean like "how much run time I can get?" or "how fast will this setup go?"


Thanks for sharing your meltdown Mark. It must have been one of those bulletproof ones.

Exactly. It's not rocket science. If you get 10 minutes with 3.3Ah cells, then you'll get around 13-14 minutes with 4.6Ah, and so on. And there are tools out there to calculate speed. They just need to take a couple of minutes and just try to come up with an answer instead of asking the first question that pops into their head. Many times, the SAME question is asked by someone else just a few threads down on the list!

Man i hope my MMM doesnt turn out like that. I have an 8xl and while it gets the job done as soon as i get some extra cash i am buying a neu. There is now getting around it.
Brian -
i have friends that ask all sorts of silly questions and 9/10 it can be answered with your R/C Calculations. It gets annoying.

Oh I agree with that and what BrianG said as well, unfortunately it doesn't stop the morons from buying them. The fluid rules are real nice too, like which manufacturers they will allow to support their own products and which they won't. I also got warning points for a post I had made two years prior with "LMAO" in it. When I questioned the moderator on it he told me to stop sending him messages.

The posts that really got me annoyed though were the ones suggesting how great a single vxl setup was in an emaxx. My only real concerns were not so much the people doing it but the people that would actually follow Q and put it their trucks then have it fail on them.

Macrow, I also was not referring to legitimate setups like you have posted. I would definitely file yours under the crap happens category.

Anyway, there are plenty of other forums full of idiots as well cough "rcuniverse" cough.

Damn, that MMM looks pretty much well done

Traxxas forum = epic fail.

Im trying my best over there to educate people, but still the same old questions pop-up, and still people just appear with a "please list all the best motors/esc/batteries/etc" thread because they are too lazy and/or stupid to do their own research.

Then again, it is fun playing God to a bunch of noobs.... :yes: :whistle:

If you are their God then the world is really in trouble Neil! :diablo:


:na::na::na::na::na:

Boys, don't get your panties in a bunch. These are indeed just kids toys. Nothing serious about them. Traxxas is a huge, popular name brand. Thus many kids buy them, thus all the noob questions. It's because they are young and new to the hobby. It's really a kids hobby. Oh and I don't use those speed calculators, they are not worth a "crap".:smile:

Wise words triggeraa..there's alot of kids buying these trucks also and there just trying to learn (arnt we all?)...I know it gets old hearing the same old questions over and over again...hell i'm guilty of it many times myself and i'm far from being a kid......just turned 60 in April...i'll never grow up

I was running my truggy in the street today showing a mate & I actually got the motor, speedy & battery to warm up.

Normally, it'd just be the motor & battery. I hope I'm not in for a failure as well.

Also, I emailed CC about the BEC adjustability in the MMM & have not heard boo from them, not even a "We have received your email & will be in touch shortly." email.

What the?

I emailed Castle a few days ago and I don't think I got one of those we received your email, emails. It took them 3 days to reply but remember they would be receiving so many emails at the moment

Yeah, good point.

I can vouch for Neil.. At Traxxas he is a GOD.. (What kind of world is this)?? :lol::lol::lol::lol:

But for what it worth, I met, learned, and soaked-up everything from guys like (Neil, Dicky-T, Jordan and others). They encouraged me and others to be all that we could be and more, it's the few who actually understood what they were providing (a strong foundation to build off) So it does pay off for the newbie’s... Thanks gentlemen for never giving up on the Nobodies, for without you I would be here myself....Sniff, sniff:oops::smile:.. Haaaa haaa…:angel::yipi:

Traxxas Forum, best forum lol Got 60% warning for saying HPI Hellfire which they would perfer HPI Truggy and saying Damn

I am sure BrianG will be glad to know you think his speed calculator is "crap". It's a valuable tool that states it may not be 100% accurate due to other factors but works better than anything else out there. Maybe you should think before offering blanket statements that cut down the hard work of people on this forum.

Walmart R/C is the kids hobby R/C. And there is a difference between noob questions and moronically common sense questions. Ex. a kid submerges his new traxxas in a lake and wonders why it doesn't work anymore. I don't care how old you are you should no electricity and water don't mix. And as far as the speed calculations, they have been just about on the money. It is called physics. Not trying to rock your boat just expressing my feelings.

That was exactly my point. No one likes to be crapped on no matter what the skill level. If you don't want to help out the noobs then do not post on their threads. I know Brian developed the speed calculator. I was being sarcastic to make a point. I know the calculator works great. Neil, while I know get annoyed at the beginers never the less is patient, witty and takes time to help out and explain/recommend solutions. He is an asset to both forums. All I'm saying is that everyone was a noob at one time and you need to can the holier than thous attitudes. If you look at some of the elitist wanna be experts on any of the forums and search their earlier posts you will find that they have learned a lot and asked their share of stupid questions.

+1,

As we were all noobs and kids at some point and time....

way OT here. there are too many self styled experts around in any forums. i never understood how there could be such a thing as 'smart experts' and 'dumb noobs' in rc-forums. all i see is users with less or more experience. words like 'educate' or 'god' or whatever are very suspicious to me. it makes me feel that some people think they have eaten rc-wisdom for breakfast. imo all you can share in forums is your assistance and experience. not more and not less.

i see that there could be high level theoretical discussions on a more formal level about some special fields in physics that apply to the rc world. not just some basic formulas but a real debate. however my feeling is that there are very few theoretical "experts" with a solid background (read somebody with at least a BA or MA in physics or a similar field) around in rc-forums. i can understand that fully. because i guess if i would really understand much of the 'background' things going on in my rc-model i would go crazy with all the trashtalking going on in rc-forums. so probably those guys prefer to stay out of such (annoying) discussions.

that leaves us with more or less mostly as beginners with just some degree of experience.

IMO, yes, stupid noobs do exist. They are the folks too dumb to use the search function on a forum and end up asking the same exact question that has been answered multiple times previously on said forum. I don't care if they have no experience in RC, if they are too lazy to at least attempt a search first, I'm too busy to help them. I'm of the mindset that today's youth expects immediate gratification and their lack of using the search function on a forum goes hand in hand with this expectation they have.

^^^^^^^
i agree. I don't mind helping the people who need helping. But like skellyo said if the question has been asked multiple times before they should be able to read up on the posts to get the answer. yes we were all noobs and young (or still young like me) once, but there has to be a line with common sense. i have always said common sense isn't very common

Exactly.

Yes, we all start somewhere, but many of the questions you see posted have been answered TONS of times (sometimes just a little bit further down the page). Just try using the search. Not ragging on newbs, just the ones that expect everyone to answer whatever inane question that pops in their heads. Like skyello said; "instant gratification".

As far as the calc goes, everyone is entitled to their opinion. If someone doesn't like it, don't use it. It's there for those who do. It was originally intended to stop (or reduce) the myriad "how fast will my setup go" and "what gearing should I use" type of questions.

Heretic! Bow down and worship me, or feel my wrath!!!

I know what you mean, like at one point after christmas on one of the UK forums, on the first page of the nitro section literally every thread was about Hyper 7's, which was utterly annoying. I can understand if the search function was rubbish (like on some if you spell something one letter wrong then it throws out random results) or if it was something truely confusing and they needed help.

Anyway, Neil for god? Smart move :mdr:

@neil
the famous swiss national hero william tell didn't even greet hat of the reeve gessler. :lol:

rhylsadar :angel:

:rofl::rofl::rofl::rofl:

Neil while I have your attention...if I put two velinions in an emaxx how fast will it be on two 1500mah nicad's?...

oh and what run times can I expect?
