MMM v2 Success / Failure Poll

[jhautz]

Nope. I voted working normally and then mine failed later. I'm sure there are others.

yeah ,i was afraid of that ....LOL...i have a new MMM v2 and NEU 1515 2.5 still in the box's and not in any hurry anymore to finish my truggy conversion cause i pretty much know it's gonna fail...
....thanks guys for the replies...

Yeah, that's what adding the foam does; suspend the PCB so the circuits clear the case, even when landing from jumps. Putting foam on the circuits themselves is next to useless IMO.

When I modded my case, I also created a slightly larger hole where the throttle wire exits and wrapped it in heatshrink to provide a little more shielding.

Yeah, having to mod the BEC is a bit on the extreme side of what a user should have to do to get a working controller. But if the choice is between a modded (but working) ESC, and an unmodded one that needs to repaired 4+ times, I'll take option 1.

I try to edit the poll results if the post is detailed enough for me to be sure what failed and what didn't, and if it has been counted as one or the other already. You should be able to see a note added in the posts where I edited the poll results.

Aside from that, it's really hard to say how accurate they are. The poll is limited to RCM forum members, and am sure there are a lot of other users out there unaccounted for. The only stats we could trust are those that CC states, and we also have to assume they are true.

Another CC employee just created a thread to report details about any V2 failures. It would be beneficial to go ahead and install it in your vehicle. If it fails, report all the details requested. Yeah, it may be a PITA to wait, but the more people that have a failure and can provide accurate feedback, the quicker these issues will be resolved.

yeah ...thats a good point . thanks, i will go ahead and finish it up ....thanks guys

I had voted that mine was working but it just failed in its second run. Please take away one working correctly and put a failed safely.

Woo Hoo! Just got my MMM today...

And now its dead. Man, 1 in 100 chance I thought I would be safe

[TruckBasher]

Well, I got my 2nd MMM but I havent connected it yet...I think Im just gonna sell it off...my other modded 1 is just sitting here...I modded it so no more warranty ...sending it back plus charges might be near a price of a MM...

Well BrianG take another off of the good list and move to the failed. Mine up and quit today, good thing I have the MGM for back up. I guess I will not try the MMM in there again, tired of swapping ESCs (third time now).

Got my MMM hooked up today with no issues from the ESC. Did have a soldering issue but thats on me. I am running a FLM converted Savage, locked into second gear with no mech brake or reverse module. I am running my MMM as is out of the box, bec and all, with the lipo setting on auto. I have run five 2s 25c 5000 packs through it, just taking it slow before going up to 4s. Temps are good on everything run time was about 15~20 minutes going through an 8xl motor. I'll get to running 4s through it in the next few days but for now all is good.

Be careful going up to 4s.
If you sift through the information provided on the "Monster Max Data Collection" thread you will see that all of the setups that have failed (including mine) have all been 4S or higher. Seems like the onboard BEC (and a lot of the CC UBEC's) just can't hack the increase in voltage.

What would be great is if you put a couple of more Hrs. on your 2S setup and see if it still runs. Then if your brave enough give it a go on 4S-6S.

Just an observation

[tc3_racer_001]

that would be if your running 3s or less, then a mamba max is more reliable and cheaper...

just putting it out there, but ur right, never seen one fail on 3 or 2s.

Ok, so I'll put a few more hours on at 2s, my truck is just for bashing anyway, and report back. Plus, even at 2s it will flip over backwards if I hit the go trigger wide open from a stop, plus it brakes so hard I can flip it on its face at full on brake.

Not to be a jerk or anything, but who really cares if it will run 2s. There a pile of 2s capable controllers out there already. The point of this controller is for the higher voltage MT and 1/8 applications. Not many of them are going ot be running 2s.
