Current Failure Rate Percentage
 

I'm defending the MMM Combo on a local track forum, and would like to use the latest failure rate as part of my arguement. I've saw some figures posted some months ago and even though they are way out of date it would be better than nothing but I can't find anything. Any help would be appreciated. Even a new figure if Patrick still posts here. My 2200kv MMM combo is still going strong.

From the local people to me I'd say it's a 30-40% failure rate on the V3, I'm at the point now where I am seriously considering taking the MMM out of the Savage Flux and throwing in a Hobbywing 150A, I was a longtime Castle fan, have had the original 1/18th ESC, then 3-4 Mamba Maxes, a couple of Sidewinders, but since the deals with HPI and Traxxas I just feel the service isn't there anymore, email replies are slow if any and turnaround times on repairs seem to be ever increasing. It's a real shame IMO.

I've had two MMMv3 and two failures. That's 100%, I have been waiting ever so patiently for my second one to come back now for almost 7 weeks. They have not kept me informed as of the status, and I'm starting to wonder if I'll ever see it again.

the fail rate is less than 1% just think how many are out there. i have never had any buff with the cc service they always get what you need back to you in a matter of no less than a month. now if we could just get neu's sevice to par with castle's

Yeah, our slow customer service is more due to the fact that Joe has been out for three weeks. It always gets slow this time of year, but Joe's absence has made it that much worse. Sorry about that!

It really doesn't have anything to do with HPI/Traxxas --

Oh, and BTW -- the return rates on the MMM are fairly low, considering how many we make, how many people abuse them, and how many are damaged after a battery pack or motor fails.

Allow me to celebrate having Patrick come to one of my threads... :party::party::party: :smile:

Great, but I saw not too long ago you put up some numbers like percent battery failure, percent this and percent that. HEHE can I see that again... I can't find it. I noticed how remarkablely positive it was.

Thanx,
Zack

PS
Thanks for an awesome overkill system that is afforable! I run mine hard but I run it right! Also I emailed Joe a few questions at Christmas when I bought my system and he got back to me within hours! Get him back in the shop!:na: But more importantly give that man a raise! :lol:

LOL, I'm just a lowly engineer here. :whistle: :wink:

anyway...the pourcentage is certainly lower vs the% of guy's who abuse the system:whistle:and the% of unit built/running<

and me too i will always defend castle...they have good products/customer service...slowly but its normal we are in summer time< and a lot abuse their system:lol:=more failure/crash system and castle have to make a lot for traxxas/hpi+the installion of the new robot arm:yes:

this is the reason why im still holding on to my mmmv1. its still performing great! ive only had one fan break on me and since ive put that mesh/grill over the esc to cover debris, its been flawless. dont get me wrong....sooner or later, i WILL exchange it for the newer version..maybe a v4 by then haha.

PDELCAST- i heard a while back, there is no warranty or return expiration date for all V1 mmm's. so will i still be able to exchange it even after say....2 years from now?
2 reasons why i dont want to exchange it right now is because it may take a while for me to get my new one.
and the other reason is because its still working and id rather return it if or when it breaks...like what if my new one breaks...and my v1 was still working, id feel pretty dumb.

Yeah, no warranty expiration date on V1 or V2 MMM. :yes:

and i was happy to pay the $70 for the v3 that i shorted on my rx line :oops::whistle:

id say low. just like everyone else said...there are alot out there.


I think whats adding to so many failures lately is that traxxas and HPI are RTR's....they = noobs. LHS want to sell them for larger profit.

rtr=noob
noob=mistakes
mistakes = angry forum flaming
angry forum flaming = noob!

WOW i just made math

thats what i like to hear! in that case, im not gonna send my v1 in until it breaks. i do like the newer versions though only cus it send out 6v to the servos instead of 5.5v...is this true

I have a V2 that I used sunday in my GTP 3S 8000,Neu 1515.5Y 4400 kv and the battery overheated before the MMM v2 did and the MMM never did overheat.I would have expepected the MMM to get hot 1st.Now I realize this setup can potentialy kill my MMM and battery but its so freakin fast.I was 1 of the 1st to even get a MMM1 and it failed but CC did right by me.But still I monitor my vehicles setups to be sure of no failures.

I would have to defend some of the abusers/misusers. The documentation that is being supplied with the MMM systems clearly states that, "High quality batteries are not needed, but will not perform as well", Or something like that. But in reality and later learned once failure occurs this is bad information. Bad batteries are killing the ESC's, at least that is what I was told by support. I know the MMM is a powerhouse. But until the manufacturer educates the end user properly before damage, they can expect alot of failures.
Just my .02 cents

my v2 is holding in there just fine on my buggy with 5cell

All these replies and I still haven't seen that set of info I'm looking for! LOL Patrick?

I am kind of curious myself. But like you I think it is going to be pretty low failure rate.

Well, I can't give exact numbers... cause we don't have the breakdown on returns for V1 V2 and V3. But so far this year:

Built: 25740 (V3)
Returns: 540 (V1, V2, and V3s)

Note that the build is just V3s, but returns might be V1, V2 or V3. I've got someone working on breaking out just the V3 numbers.

Wow thats actually very impressive.
I was thinking good, but this is better than I thought.

yea, thats ALOT better than what i have thought as well.
well actually, i thought there would have been less than 540 returns but i didnt know CC built 25,740 units.

i doubt all 25k mmm's are being used right now though. prolly still on shelfs at stores.

I can tell you there aren't that many on shelves. HPI and traxxas don't buy them to sit on them. Horizon may keep a thousand on hand TOPS, and most LHS won't have more than a handful at a time. I can tell you Castle doesn't have them sitting around either, cause there are backorders for them.


I just burned one up, but it was the servo's fault. servo gave out and shorted the BEC with it dangit.

gosh darn it those are fantastic stats for the hobby - rock on...

That's probably the lowest failure rate for a MT/8th ESC I have seen in the past 8 years.

Wow...impressive stats. I love all my castle controllers. My mmm v3 w/the new firmware and my 1512 Neu is soooooo smooth in my buggy it is scary

I find this very interesting, since I've burnt up two units on two different battery combos!!

Great job Castle! Keep up the awesome work!

Thanks Patrick! Those are good numbers. Maybe once you get the V3 broke out you could post again. Still I have seen a nearly exaustive cover of the returns a few months ago maybe even as far back as in 2008. If anybody know of what I speak let me know and maybe we can locate it. :smile:

How many V1s and V2s were produced, think it was like 500 of each or some quite low figure ( RCM guinea pigs ftw! :lol: ). Still grateful for my V1 thats live and kicking :yes:

1000 V1s and 1200 V2s were shipped. But we will honor warranty on those units with no expiration date.

Hopefully word gets out and people will stop bitching about "failure rates"

I know BrianG and others have said this many times and I think common sense should prevail in this as well.

Commonly people come to forums like these when they have a problem and nothing more. I would guess 90% or more come because of a problem and this would reflect across all types of support forums. Most people come to seek help, get an answer, then leave. Nothing wrong with that at all I will say. But just looking at this one would deduct simply that most of the subject matter on the forums will be complaints and not praise. This can also be found in the news media as well. You cannot look at the number of complaints on internet forums as a key indicator of true failure rates because the information is already skewed from the beginning.

I would venture that most people have a problem then do a google search for help and this or another similar forum comes up and they go there and complain. It's not a stretch to understand that most people looking for answers these days seek the internet first and foremost for help.

I for one would just like to know where my unit is I sent it in on April 20th and received confirmation that it arrived on the 23. I have not heard or seen any thing on it!! I'm starting to get a little pissed.

Well now I just checked my email, and there is a statement for a replacement unit!!!! Great news right? But it's dated 5/22 and its now 6/18!!!!

Your complaining about their communication, yet you havent check your own e-mail in three weeks?

-Brian

I have a Blackberry, I check my email constantly. My point is that the date on the invoice is 5/22 and I'm just now getting it!!!

For what it's worth, I had a V1 that failed back in 12/08 and was immediately replaced no questions asked. Since then I've purchased 5 more V3's with no problems. All my friends who have V3's (all 11 of them) have zero issues also).
Keep up the Great work Castle ! ! !

My V2 is still working flawlessly! I did need to replace the fan and switch however.

Two V2s killed themselves in my truggy, they were replaced with no question asked, I live in China, all I had to pay is one way international express, awesome and promising service.
