I got 1 of mine back today.It is in my 8T with a Tekno Neu 1515/1.5d/f and Maxamps 4s2p 6000 I ran for about 10 minutes and no problems to report.The temps here are in the 80s and the fan only came on once.I realy hope these failures are isolated incidents.Thanks CastleSorry guys that sucks yours failed I know you have been waiting.I think I will keep my mod MM for good luck.I hope and wish I dont need it.

oh yes....ive run 3 differnt sets of 3s through it..ive run 3s maxamps 5000's.....3s venom 5400's and 3s maxamps 6000's.....the last 2 actually fit in the battery tray, but you cant close the door!

im telling you..the esc never got over 104 on multiple 6s speed runs....it was performing flawlessly!

the failure occurred right when i turned on the switch

MGM here I come!

Oh man...this is turning into a total disaster. Sounds to me like some sort of internal short, or perhaps, for some reason, the TVS blew? That seriously sucks though; sorry to hear about it. Lets just hope this is an isolated case.

i hope its just an isolated case...i have another one on order!

I believe he just cut the lid off, to allow for more natural air flow. A few others have dremelled the inside of the case, so that the plug for the fan doesnt rub on the inside of it (under the pcb, bottom half of the case). A few have ran the fan wires out of the top of the case and plugged it into the Rx, using a new fan though that isnt so prone to busting.

EDIT: beat me too it...

Its hard to comment on something you I dont have yet...I have 2 on backorder and now im thinking Luciano was right to hold off for another 6mos to make sure everything is good. I still hope this is an isolated incident and wont happen to other MMM V2.

Another one dead during calibration , was just posted .It's not looking good .

[glassdoctor]

Maybe that is coming someday?

I'm still running a MMMv1 (haven't run it since may-june) and I just removed the fan and cut the top off the case. We'll see how it does once I start racing with it again.

My v2 appears to be working flawlessly. I will race it this week and see if it holds up. My 3rd v1 has done very well with no fan. I have raced the bejeezus out of it with no problems.

I do think Castle over thought this ESC. The regular MM worked flawlessly. I would have just took the regular Mamba and made it for 5s with the internal BEC and been done with it. Heck, 4s with an internal BEC would have been fine for most people. I also think most of the people buying these would have spent up to $300 for a flawless ESC. Cutting corners for a low price is nice for to attract the bashers, but I don't think that is who is really buying these right now.

Nevertheless, I love my MMM from a performance standpoint. Most of the mods I have made to mine are to improve durability so it can handle the jarring impacts from constant racing. I think the this is where they dropped the ball. It is fine for street bashing and flying across fields, but the design isn't really cut out for 1/8 scale racing.

Even with all the flaws, the customer service is next to none. I am a happy customer.

I was referring more to the design... fan and case breakage.
