Sounds right, I was not the 1st to get a V1, but was the 1st to put it in a truck and do any real world testing with it, I received mine v1, 2 days after the
first one were received. have you opened the case yet?

My MM that failed on 5s was similar to yours. Power on and fried before I even got to pull trigger.

Thats fantastic, now I don't know if I should even run it for fear of frying my battery. When my V1 went up in smoke I only got lucky that the battery did not go too.

I guess I'll ebay it and stick to my nitro for another six months.

There is NO WAY the controller will "fry" your battery. Especially if you run decent LiPo cells. Unless ALL of the FETs shorted at the same time (completely impossible). Whatever shorted would not be able to handle the current and would vaporize instantly with the 150-200+ amps put through it that a decent LiPo can produce. And you know what? If the battery did puff, it probably wasn't rated correctly! All of the failures I've read about thus far have been BEC/fan related which DEFINITELY would not hurt the battery AT ALL.

Thanks for the links to the MMM mod guys

However now i think about it more, what phatmonk said is very true and i am actualy getting peeeved now.
It's alright for us since we read these forums and can perform the mods .
What happens to the normal kid who buys one of these to run in his emaxx / revo and doesn't get on these forums as probably 99% of MMM customers.
How are they suppose to know how to perform these mods and that the mods are even needed .Not to mention that these mods void your warranty .

I couldn't wait to get my MMM , iv'e been waiting a couple of months now on backorder ( missed the first batch of backorders )
and have a new X2 truggy that i haven't run yet because of this delay.
It's sounding like some of you guys a crossing your fingers and hoping for the best when running the V2 .
Shouldn't you be able to use a product without the fear of it failing in the back of your mind.

I have used and still will use my MMs and i am buying a new Sidewinder for my 1/10 Pan Car , however i don't think CC should of released the MMM V2 if you still have to cut it up and mod it
Every issue on the v1 should of been rectified with the v2 which looks like at the moment this is not the case ( fan wires fraying and causing shorts , 2nd case of this happening is on RCtech forums ) and the need to run a seperate fan.

Think i might cancel my backorder and get another R1 Pro for the truggy .

Yes it is possible to lose the battery. When my V1 went up in smoke the wires from the battery lead to the esc board came unsoldered, had they shorted out in the chassis or together then the battery would have went up. The battery better have been rated correctly for a $260.00 Polyquest.

My question is this. Is this ESC for bashing only? I mean do you just put it in your truck, truggy and run it around in the street or in the grass? If so then the speed control works awesomely, but I plan on racing with it. Airing it out over large jumps, getting tangled in traffic, etc. If this is the case, and it's not built for racing then please CC let us know.

Thanks.

imo the price is just too low... i would have preferred a $250 controller which was bullet proof not a $150 controller with issues... even still i cant wait to get mine :)

look at the mm tho, 120 and performs flawlessly, i am sticking to those, no point in going 5-6s for racing

Dude, there is no way I am keeping the MMM is modding it is required for it to operate properly. That's totally obsurd.

'm all for modding stuff to make it do stuff it wasn't intended to do, but that's a different kinda thing.

Having to hold my new ESC's hand while it crosses the street is pretty much the opposite that I am after.

I agree, it's like the Quark, or was it MGM, that needed the FETs sanded and a RCM heatsink and fans to function. It was rated for 6s but couldn't do it very well without mods or with mods for that matter. That IS absurd. The MMMv2 seems to be plug and play so far. There has only been 2 failures so far and 1 was user error.

Thanks.

That wouldnt be the esc killing the batts directly though would it, that would be the ends of the wires touching and shorting, but the odds of them staying jammed together like that for more than a split-second are pretty slim.

As for the escs durabilty- just stick a zip tie around the case and that stops it from coming apart (as I found out). Mount it low as possible on the vehicle and you'll be fine.

The ESC melted down into a stinky pile of plastic.

I should know better than to post on forums.
