Rip Mmm
 

Yep, another gone.. (its a v2, only had it for a day-ran it for 10 mins)

was running on my driveway, thought it hit the cutoff, check the battery it was fine-then lowered the cutoff a bit- 15.5v, then plugged the the wire back into the rx.. turned it back on- it armed , blipped the trigger.. stopped and shut off. Never smoked fan didnt come on but castle link still works!!! i dont get it:neutral:

ugh

red led on ESC flashes once when i try and arm the system, i can also hear the servo centering itself as i pug it in... but then nothing

Sounds like the BEC to me...

would the mods that u guys told me prevent that failure?

It should, but there's no guarantee. That's the risk you take when doing something like that. I've had good luck, and so has another member who has tried it. You may not be as lucky and then you'd be out the cost of a new MMM.

well i didnt open it, i started to but thought better of it.. its back in the box.. waiting for patrick to respond to my PM

I've ran about four packs through mine, the first three were smooth as glass. On the fourth one I set it on the track, went down the straight and it cut out. Turned it off, unplugged it turned it back on and it worked again. Then about eight minutes later it did it again. Turned it off unplugged, turned it back on and it ran smooth the rest of the pack. The only thing was the servo felt really soft the whole time, Hitec 5955.

To me that means the BEC has got to be the problem with these, other than that it's an awesome ESC.

agreed

They need to make a setup like the MMM that brian modded and have some leads to plug a ccbec in...

since the bec is bad, can i try a rx pack?

Give it a try. You've got nothing more to lose :lol:.

Wont work. They're all failing the same way.

is it a worthwile endeavor to remove internal BEC?

Unsure how this would work. Using any external power source will power your servos/rx/fans/etc, but if the BEC is going bad just by itself, that will still leave the brain circuits without power and you are still left with a dead ESC.

doesnt matter now, it smoked.... :(

PATRICK, WHERE ARE YOU?

SUUUEEEEEEYYY
:lol:

Try turning the Auto Lipo back on, see if it starts working again.

I think we might have a bug in the cutoff settings that won't allow the controller to arm when cutoff is set to a fixed value.

it let the smoke out... completely stopped working... :( its back in the box im afraid to touch it :lol:

It finally happened to me. At least I got to use my burn plate that I made! :lol:


...Casper, in all of his wonderous glory, came pouring out from under the body.!
Accompanied by a hissing sound we all started running towards the truck.
Pulled the body off as fast as we could and pulled the batteries off of the flaming ESC!

Dude, I gotta be honest...


...it was AWESOME! ha ha!

Its too bad that no-one had a camera.
I took pics when I got home though...

here ya go fella's;

Too bad it happened today, I wont be able to call until Tuesday... oh well.[/QUOTE]

hahaha, at least my didnt combust :D

Pat check ur pm's

:whistle::whistle::whistle:

WOW....now I'm afraid to even take mine out of the box....just got mine .... thought i bought the best of everything for my first conversion.. LOL...from what I'm reading on here,you guys are making me really nervous to even wire it up in my build ...lol

me to is dead...v2 version im really tired of this....!!!!i try it today on 6 cell 1.5d 1515 neu and a e-revo....i do 10 feet and nothing....no rx ...nada....just stop ..the esc try to arm but just this....i have to pay 25$ to ship my esc to cc each time it failed!!!????no way!!!now i understand some guy's who are tired to ship one esc each week to cc :mdr:

please cc fix this...!!!!!

I knew these v2's were gonna do this...it's gonna be a few months before the bugs get worked out. It will be a solid control its just gonna take some time. I said I wouldnt do this but I might grab a couple of em next summer. Ps my two bad hydras are doing the exact same thing! I mean their not arming.

i try the inverse...my esc was on the auto lipo mode when my issue come...i put the cut-off to 18v and for 3 min it work!!!!!

i will try this now in the street...ill be back in 15 min for a review!!!

its going to happen, when you have deadlines all things cant be adressed right away, i have lost no faith in CC, it happens to all things and MFRs, either get rid of your MMM's or deal with it. im keeping mine.

after 5 min my v2 died(this time its real)nothing to do....im able to set the esc with castle link but no power on ...rx etc

me too i lost my faith in cc

get back to castle monday....

thats the bec, mine did the exact same thing

My MMM hasn't arrived yet, but I'm trying to learn from all the experience here. Granted, there are those that are frustrated. I can understand those feelings based on the months of waiting and returning items. The only way things will be resolved is to continue to post failure conditions and find the weak link(s) involved. I for one, am willing to post pics and vids of my experience once the MMM arrives to see what happens. Based on what I've read, there could be a BEC issue. I'm running a Tekno-converted REVO with ACE 1015 and 1313 servos. Should I use a CC BEC to spare the MMM from having to power these servos?


Oh yeah..Brian G, haven't forgotten about you.. I'm sending a little box your way.

the problem is here in canada due to custom fees and change rate(us$ to can$)it cost me close 200$ for a mmm.....

now i have to ship to cc 200$+25$(shipping)=a controller reach 225$ minimum...plus more$$$$(if i have to reship in case that my esc failed again!!!!)

I have a v1 mmm and I am using a ccbec and also took the fan off of the esc and wired it to the rx....so far so good. I also cut the grill out of the fan case to prevent the fan blades from hitting the top of the case. The decision to run a cc bec is up to you. It will void your warrantee. Just something to think about.....good luck!

"The decision to run a cc bec is up to you. It will void your warrantee. Just something to think about....."


Wow.. really? Hmm.. well I want to be able to return the esc if it fails. Maybe I'm not so "willing" to experiment after all..

That is not true.

Why do you say that?

The way BrianG did it will, but not doing it the way castle recommends.

a guy at the track today had the mmm in his buggy it ran great for a bit, then took a silent death, his truggy is still goin strong tho

Lol, that's one way to disable the BEC! (I see the BEC coil laying in the carnage)

your right:yes: so it should work now? right?:wink:

My gut instinct says no. :lol:

:lol:

I tried to plug it in my computer.
I think my castlelink is broken.
It's not working.:neutral:


















:lol:

Hoovhartid? I just did!...lol. Just kidding...did your lipo suffer any damage?
