took mine for a 1/2hr use and its still working. update if it does happen to cark it.. fully stock bar a bit of unshrinked heatshrink tubing over the signal wires and switch - they looked like they would get worn down took quickly.
also: i know this thing can pull more than 110A -hooked up my wattmeter inline and its rated for 100A max... very happy with the zippy pack ive got - just a bit too heavy!! |
Two more failures and the poll will be dead even :intello::intello::na:.
|
no. only 1 person who has added working to change :D
hope its not mine! |
Well, I started this poll 9 pages ago and I finally voted tonight. Thanks to bad weather, the last two weeks of racing have been cancelled at my track. I've taken my MMMv2 out twice for some testing around the house and once for a set of packs at the track but I didn't want to vote until I had a full day of racing, 4 sets of packs through it. Today was that day. My MMMv2 worked flawlessly.
But... The guy pitting next to me, also a member here on this forum, had a nearly identical E-Revo to mine and his MMMv2 fried! Same mounting position, also running 4s. His just stopped and smelled of burning. So on the day, out in the real world, the MMMv2 is still at about a 50% failure rate. I'm very worried that mine will die at the worst possible moment...I sure wish that Castle would tell us what's going on. |
I have another new V2. Do I get to vote again for the 2nd one?
Are there others out there with more than one V2? I'd like to get a true read by letting people vote for all of the V2s they have rather than just once. |
I have 2 ....one died (no warranty..modded version) and one that had 15mins only still alive but inconclusive as my truck broke a couple of alu before I could test MMM :lol: (and no I havent voted yet for the 2nd one :neutral: )
I believe Brian is trying to add both working/failure units for users that have multiple MMM... |
My second one died today. Anyway of putting another failed up there?
This has to be CC's worst nightmare. |
i purchased 5 .. the first one died today , 1 full pack flawless , 2nd pack turned on , and now seems to be a bec problem .. lets see how the next 4 go ?
|
I have had 3 more die from exchanges. 2 BEC failures and 1 up in flames.

and the worst for me its that i have 3 mmmv2 in the mail.....arrrggghhhhhh |
I've got 2 V2s back from Castle a while ago but haven't had the nerve to try them out. Reading the posts about them going up in flames has got me spooked. I've got one almost ready to go, but I'm just debating if I want to use the CCBEC or not.
It really boggles my mind that I can run a MM/CCBEC on 4s all day long in this big, heavy truck, but my "badass" MMM fails. |
me i will go with the internal bec....and modiff the case:yes:and cross my finger...
|
Is your finger are long enough to be crossed:rofl:
You can't reach the brake on your Tx :lol: |
lolll....:yes:
|
I have installed my new MMM in my 8ight-t but i'm not sure if I will test it with the internal bec or with castle UBEC I have :eyes:. One thing for sure, I have install a cheap receiver AM and cheap servo just to be sure in case of fire...:gasp:
|
I took my Cen Matrix out today and ran Neu 1512/1.5D on 3s and my MMMV2 worked no problems only 15 minutes though.So I said what the Hay I am putting my 4s 6000 battery in and seeing what would happen and the MMMV2 worked great and it was AWESOME!Way to fast Yea it was a rocket I only ran 5 minutes till the Autocross tires almost shredd off the rims.Basicly speed runs on asphault.
|
Which motor have you put in your eight Dany??

I think that this controller is rated for 6s, but not able to take it. I've sell my Neu 1515 2.5d to e-mike, and i'll try my MMM in my Slash on 3s only. When CC will be able to make a solid and true 6s controller, i'll put bake my e-veo on the track. But for now, my e-revo is sit on the shelf and stay it as long as i'll find a good controller for 6s. |
Yea I agree it sucks that you have to be hesitant to run the MMM v2 on 6s or even 5s.I was afraid that it would poof on 4s with a 1512/1.5d.But Iam not going to baby a controler that they say can handle more than I can throw at it.If this one fries its back to CC then when a replacement arives it goes on ebay
|
yes try it on 6 cell:yes:
|
Anyone know if castle will do a recall? I sent mine back last week. After 5 minutes, stopped dead.
Max amps 3000mah 6S, Lehner Basic XXL 1800 (87 amp, max) Traxxas slash. No fire, no smoke, no smell. Just dead. Could link it still, I tried flashing the firmware but that didn't revive it. This was all before I knew of the BEC problems. Hope the new batch is solid. I'm not demanding much from it, but it sounds like the BEC is having trouble switching down from ~25volts to ~5volts. |
just like you coreyfro we waiting for some answer....and updates:yes:
|
Early days and tempting fait for sure but over this weekend I finally had chance to run 3MMM’s v2:
- I ran a full pack of hard bashing (lots of crashes) though my G-Revo setup MMM 6s2p A123 1515 2.5D 5955TG with no issues - Two packs of track, bashing and torture test (full throttle, full break repeat x 20 on tarmac) X1CR setup MMM 4s 1512 1Y 5955TG with no issues - Two packs of track and bashing Hyper ST Pro setup MMM 4s 1515 1Y 7955TG with no issues All of the got up to temp enough for the internal fan to run. I would add that all are running an UBEC, switches have been removed, telfon washer and heat shrink added to fan. If you check the CC threads CC have repeatedly said they think this still might be setup related in some manner and are in the process of collating and testing machines that have repeated failures. At this point I'm not sure what more they can say until they have actually concluded the testing. |
My pre-replacement MMM failed yesterday, broken fan & dead BEC. About 2 hours of run time on it.
My Total dead MMM reveiw: MMMv1, Dead BEC, broken fan. MMMv1 (repaired from above), Dead BEC, broken fan & fan connector MMMv2, dead Fan controller & BEC & broke connector MMMv2 (pre replacement for the one above), broken fan & dead BEC I have one that has been run for about 30 minutes, still working. I have another that has been working for 2 to 3 hours of run time but the fan died & the fan connector is broken off the bottom of the board. (I have installed a Novak fan that is pluged into the RX and have cut the grill out of the top of the case. So 4 out of 5 have broken fans or connectors or both & the one that has not broken the fan has only 30 minutes on it. |

...and more about the fan mods you did ??where does the heat shrink and washer go ? thanks for your help |

Fan mod is simply a teflon washer superglued into the middle of the fan case.
http://www.rcproductdesigns.com/images/jhautzShim.jpg IMG: Care of Jeff The heatshrink is on the fan lead to avoid it rubbing against the PCB. Quote:
|
why add a washer at this place....??????
and do you remove the foam on the lid and make a groove....??? |
so it rubs in the moddle of the fan, protecting the blades
|
After running my 2s packs for about 4 hours of run time I ran a 4s 25C 5000 Poly RC pack through my MMM with no issues. Ran the truck hard for about 12 minutes ESC temp measured 120 motor temp was 155. Trucks gearing is 16/47 with the Savage trans locked into second. It was only one pack at 4s but great none the less.:yipi:
Darion |
thanks arct1k for the pic and info
|
I still haven't had no issues with my fan. Still might look at doing this washer mod though
|
My V2 stopped working after 10 min.
6S NEU 1515 2Y in a mugen MBX5 Yes, this is Dafni's old faithful but unfortunately, old faithful's maiden voyage was cut short by the dreaded bec bug... Now if only I knew how to perform BrianG's bec mod...... :whistle: |
Even Old Faithfull could not lift the MMM curse... :surprised:
|
My V2 Monster died silently after about ~20 min total runtime on 6s.
Now it just started it's second life as a MMM V2 lite (BEC removed, thx to BrianG). :party: So far everything looks well, but I have no real runtime on it so far. |
I let a friend borrow my V2 that was int he box when he got it.. He said he made it 3 packs before it died completely.. He was running it on 6s, it would turn on then die a couple of times and then there was nothing.. he burnt the BEC out of his V2.. My V1 I have been running on 5s for multiple packs.. the only thing that I have had go bad is the fan stopped working so I strapped a 5v fan out of a blade server that keeps that thing way cooler than the stock fan.. no problems with it other than that..
If I unplug the motor should I have to re-sync my radio? I did have the happen and didn't know if it was normal... |
