Still on the gas and kicking a** with my V1.

That's what I was thinking, something else must be wrong here?

[JerryF504]

I was thinking that also. I'm not real familar with the internal workings of a computer, but I wonder if it is possible for a usb to put out more than 5v and damage the ESC.

First of all: sorry for your loss, man. That really bites.
Dude, I've got 2 of these things on order and now I'm starting to feel like a sucker for not heeding all the signs.
Time to email castle a letter of concern...

Couple questions just to be clear:

-Was this an E-Maxx that has already been run with another system in it, so the radio was already set up?

-Had you tried setting up the ESC via the USB to a PC before hooking it up?

I've got a spektrum, so I'm understandably curious, I guess you could say.

I just got back from running my V2 for 25+ minutes almost 4 hours total on it, Today I switched from the 9xl to a 1515 1Y, 5s Neu 30c 5ah, Gmaxx 65/24, nothing but creamy smooth acceleration and amazingly low temps. Dont fear the V2 most are running like champs !

[J3110]

Ah, that's great to hear. Guess I'll just cross my fingers n hope fer the best whenever I get it.
Torture that sucker jayjay. :)

why did i sell my entire nitro collection again?

Open it up and post some pics to see if it has the padding on the case etc that CC improved.Maybe a wire is pinched.Just a thought.

[Larrydino]

I feel your pain..i was the guy who had the 1st v2 go up in smoke!

[What's_nitro?]

I'll still buy one when they become available. If if goes on me, I too will be sticking with MGM from now on.

I thought I read in another thread here that they were going to test all of the MMM before shipping them..?? Wouldn't that include calibration? If so, then I hate to say it but it probably was the Spektrum that killed it. I have no idea how that is possible.

[mk351e]

here's my system:

losi muggy
tekno neu 1515 1y
MMM V2
6S hyperion 4800
spektrum 3 channel radio
spektrum pro rx
futaba digital steering servo
deans connectors

i didn't plug and unplug a lot. BUT, every time i did, i had the appropriate resistor in series to charge the caps slowly - I soldered one up with deans on both ends for a nice finish! I used to install car stereos, so I know to charge caps! ;) Also, the controller was completely set up with castle link before it was put in the truck. I also read the instructions a few times before I did anything. And as I said earlier, I even upped the arming time on the MMM to 5 seconds to account for the spektrum delay. The radio and rx were already bound of course, and I am not new to spektrum - I've been using this remote for a couple of years. all settings were set to zero on the remote, except throttle endpoint, which was at 115%. the mystery pop happened during calibration - batts were plugged in and switch on.

basically, I feel i've crossed all my t's, and dotted all my i's, and i'm still scratching my head. again. I do feel however, that there is an uncanny similarity to the MMM v1 here, and I wonder if it's me and/or my system, but as I said, I'm completely lost at this point. I would love to open it up, but NOT b4 I call CC tomorrow.

here we go again.

Have you run this set up with another controller?

[mk351e]

nope, this is my 1st real BL setup (besides my micro T). just a few months ago, I was asking questions on these forums nonstop! I sold off all my nitro stuff to do this, so that's the other reason I've been so pissed lately - i don't have any nitro, I don't have any electric; I have nothing since march basically!!

however, I don't get it though, I mean CC themselves even told me this would be a killer setup! I consulted with them before I even bought ANY of this stuff!

[mk351e]

i just tried to plug in my MMM to castle link in an act of desperation, and I while nothing happened, the castle link board got very hot. Hmmmmm

Your castle link may be powering the esc with too much voltage, possibly killing the internal bec... Did you send the included castle link back with the v1? Or did you keep it and they just sent you a new esc, without the castle link...

I would send the castle link back with the esc, and have them test it. It must have some sort of pass thru, as most usbs output 5v...

That's what would happen with my V1 escs after they died. It almost sounds as if they have accidentally shipped you a V1.

I don't think we would have accidentally shipped a V1, we were very careful to pull all V1 circuit boards out of production to prevent something like that...

We need to get the Castle Link and the MMM back -- so we can see 'em here and figure out what went wrong. Most likely a bad component (infant failure)

Thanx!
