yes i have

Nah, it's easy to get a percentage, as long as people report that it died.

my v2 went up in flames in less than 5 min. A few wheelies out to the street, then forth of july colored flames before i even made one run.

Funny the fan didn't come on while it was burning, that should have been more than 150deg right ?:lol:

My MMM came in today and is working fine. I decided to run it "stock" even though I've placed an order for a BEC that should arrive next week if something happens. As well, my NEU 1515 2.5d hasn't arrived yet either, so I'm using an Align 600L with a Tekno conversion/clutch on 6S. Still have wheelies on demand and way more power than I can use..

got my first monster back today as it was "repaired" U1 resoldered.........
set it up on cc link and plugged it in and turned it on PUFF white smoke.........
this is #3 and i am supposed to get #4 next week
so if anyone is reading thats 3 with 10 minutes total for all three.(one ran other two crapped out when they were turned on)

I have had 1 v2 so far - after 15 minutes running hard it's still working normally and I just added it to the poll.

I haven't plugged it into a castle link yet.

I'll respond if it blows up.

Well. My V2 died. :grrrrrr:It was acting wierd the last time I ran it. Not firing up the first time I flipped the switch and random crap like that. I went to turn it on tonight and it fired up and ran for 20 seconds and then shut down. I can get it to fire up randomly, but what it looks like is the BEC is putting out around 3v rather than the 5.5v its supposed to put out so the reciever cuts in and out just at the very edge of what it can run at. The servo is slow too when it is actually fired up. The V2 lasted one race day and 1 short 2 pack practice session before the BEC acted up.

So... the V1 that has been working for quite a while now(probably 6-7 hours of run time on it) is going back in. I'm glad I didnt send it in for a v2 replacement.

I hope they get this figured out. SOON! Its going back to CC Monday morning.

I'm just about ready to go back to the old heat moded Quark I have. At least I can count on that ESC. It has many many hours of reliable service.


Anyway I already voted sucess.... Please deduct 1 positive vote for a negative vote.:grrrrrr:

both of my MMM's are working so far.....I've got a v1 that has countless hours on the track...8ight Neu 1515 1/y/f 4s 5000 thunderpower lipo.........and I've got a v2 in a Muggy 9xl 5s 4800 elite lipo.......that only has afew hours on it but is still working......my V1 has the fan and case mods....my v2 has zero mods.....

im scared to see 31unit working good vs 27failed ....:rules:

shouldn't these things be bench tested before they go out?

Don't forget that those numbers reflect only those who post. There must be others that work. Not everyone running BL is a member here ya know! :wink:

cc should do a better range test....''PUFF''a controller just to power on not a normal thing.....:sarcastic:

right...but we can have a good idea with the % about non failure and the working unit....and the opposite can be true some guy's have a failed unit and dont post here....

and why my first v2 run great 2 run of 25 min on 4cell and failed on 6cell after 3 minutes?????

20 minutes and the turd failed then i called castle at 455 central and it says theyre closed there hours are monday through friday 9 am to 5 pm they shut there phones off early grrrrrrr

remember guys, the failure rate is less than 1%.

This forum is obviously just a gathering place of unlucky people.

Our sample size is up to 60 and we are still around a 45% trouble rate. Something doesn't jive...

Yeah but the 1500 in transit or on shelves haven't failed yet.

I was being sarcastic, I should have used a smilie but was eating a muffin and typing at the same time, you know how tricky it can get driving a keyboard with one hand.

Actually its not even that good. I voted sucess prematurely and would like to deduct my "working" vote for a "faild" vote.

No... but just about all. And it shouldnt matter. as long as we can get a statitically significant sample size we should be able to estimate the good/bad percentages within a reasonable number. The ESC showed up to use randomly so the failure rate should represent a random sampleing.

+1

I just got my 2nd preordered V2 yesterday and I'm afarid to take it out of the box at this point.

Hey dont fear the MMM V2 Reeper!My 2 MMM V2s so far work great

:lol:

The poll is statistically accurate as long as the same % of people with failures post as the same % of people with success. I still think there are more successes than are being reflected here. How many more? Who knows? The only true gauge of that would be to tabulate the returns at Castle.

IMO, this poll is just roughly indicative of the failure rate.

lets castle do a review in the next week about the failure rate.....could it be better...that the v1

wow 33 and 28, thats not to good. my question is out of the 33 that worked when they voted, how many have stopped working since then? its looking like they ALL fail eventually, i could be wrong/ and or bitter. #4 and #5 will be my last MMM's, if they dont work screw it. i dont think a company shoul take money from cust. and give them a product that is going to fail. they just got sued right? well what if someone is injured because their controll flamed up? not that it will happen but then again the MMM was suposed to work, the first time, now their are two versions? seems like the production of these controllers is the problem. the first one i had died during calibration and it was "repaired", cold solder joint @ U1. a cold joint? wtf? then i get it back and turn it on and puff!!! yeah i will admit they have been nice to my wife when she called but that is at an end i will be calling next time. good cust. service doesnt mean $#!* to me if the product isnt worth the trouble. sorry all for the rant but i am getting tired of the continual disapointment.

Opened a new V2 yesterday. Installed, no mods. Ran it around for a few minutes in the parking lot, then it just stopped. Very conservative race setup using a clutch and mechanical brakes to take some of the burden off of the ESC.

1515/1.5Y
Neu 6s/3900
Tekno V3 MBX5-T
13/48

Our MMM V1 with fan removed is still functional with no issues for a couple months now.

please stop buy this sh&*%?$?&%?...:rofl:when a compagnie ship your product with a pre-paid envelope(for return) is not a good thing....:yes:

my v1 and v2 are running strong +2 in the not failed category
 

i have about 10 hours on my V1
I have about 2 hours on my V2,4S8000HV maxamps, 2770 kv XL motor
20T 68T erevo. Got things pretty hot today one of the battery wires solder melted... but the ESC is running strong. Seems that more of these problems are happening at 5S and 6S.

Well I do agree that this is only rough. I think it may actually reflect more posistive than there actually are. I voted positive, then it failed. So.... unable to make the adjustment I know each side of the pole is off by at least 1 vote.

The bad thing is my in my area I know of 4 V2 MMMs that have been run. All 4 have died. 3 dead BEC and one in flames.

I personally have had 2 V1s die out of 3 now and know of a 2 more V1s that are still running. SO at this point from what I personally have seen the V1 was actually bettter than the V2. I have another V2 in the box with the seal still on it. I dont even want to mess with it. I am putting my heat modified quark back in. I cant believe I am back to the same place I was 2 years ago....:no:

sounds like your worse off, like me with more money in burnt electronics

Well as far as I know my ESC is working okay still..

but my Zippy 4s 5000 just puffed bigtime :(

Well, put me in for a dead V2.

This was the replacement for my V1. It worked for about 5 mins and then just stopped. I was doing stop and go driving because I was too lazy to go to the track (good thing I didn't).

Went back inside and plug it into castle link and it armed. Ran it again and stopped after about 10 feet. Plug it to castle link again and this time it didn't arm at all :whip::whip::whip:.

This is stock setup, no mods whatsoever.

sorry for your lost george16.....i hope that your close of cc(not far away like australia)

Thanks.

I'm currently stationed at a Navy base here in Japan so I'm in for another wait :no::no:.

:surprised:


for me here its a 3 week of waiting for a replacement.....

#3 just quit. No smoke... Just quit...
Running around the street.. It started to act a bit funny.. where it would be running a little forward and it would kind of act like it braked for a second. Did this a couple times and then quit.

Ironically enough.. this was the first time I set ANY of the ESC settings in Castle Link. I turned punch control to 70% and adjust the throttle curve a little less agressive, and of course the LVC to 12.8V.

Did you check you battery voltage after this happened?

This is what makes me afraid to change anything.. it's worked so far and I don't wanna eff it up :(

What's the default LVC setting?

-Jeff

I run mine with the auto lipo settings.After balancing my voltage on a 4s was 12.4 volt.I heard that the MMM V2 has a software glitch with custom lvc so I have not set a custom lvc cutoff.Go to the CC website to the download page for details.

i spoke too soon. mmm v2 fried this afternoon
 

mine just stopped working this afternoon. MMM v2 e-revo, 4S, 2770KV motor. 20T 68 spur
motor was hot, wiring warm, fan not on MMM.

going back to castle tomorrow. going to step down to a 2000 kv motor whenever i see the v2 again.

my V1 is still going strong.

Batteries had maybe 5 minutes of use.. Not even enough to warm up the motor over 100.
