Heard a rattle in my M.M.M.

Well, not only are you missing a part, but the inductor is also physically broken. The inductor is the part right next to the missing part (square with a circular interior.) It should be symmetrical, the bottom left corner (in your picture) is missing. Without that piece of ferrite, the magnetic path is broken, and the part won't perform correctly.

I would suggest that you return it for repair. The impact that broke free the TVS was hard enough to break the inductor. What did you hit??

I didn't even notice that, worked just fine the last run ?
The last time I ran it I didn't even hit a lot of jumps, Where I gently pried the case open was on the opposite side of the broken parts. I'm sure you've heard this a million times but,
"I don't know what happened to it ?"
Ben really busy, I'm gonna try to mail it out befor the end of the week.

ESC will be shipped to fellas Friday morning, I see on the website I can expect a month or so wait so I reckon I'll be borrowing one from another truck. Gotta have the Revo up and running !

could the MMM not just come potted http://en.wikipedia.org/wiki/Potting_(electronics)

or is there some sort of heat issue.. my buds 8ight-t wth a MMM stopped working after one crazy jump.... out of a skate park bowel at WOT.. it was nuts.. but it landed on all 4

[shaunjohnson]

could we make some kind of external shock absorbing thing to hold the MMM in place but give it a little cushioning?
some kinda flexible mounting....i have always had my MMM mounted on some double sided sticky **** plus the cables ties so it had an ever so slight amount of give to it.
when it comes back from castle i'll look into it...

Put a layer of foam under it maybe?

[Kcaz25]

Mine came with double sided sticky foam.

A guy on a german forum modifyed his MMM by making a little box around it & filling it with some form of epoxy compund. Once removed fromt he box, it looked like a black lump of resin with a heatsink and wires sticking out; great for water proofing and protecting the delicate chips, but no chance of servicing it ever again = warrenty void.

Sounds overboard and in the wrong direction ? I don't understand why he'd do that and purposely void his warrenty by encapsulating it like that ?
It makes more sense to roll with the punches and leave it alone rather than not make it servicable. To each his own I reckon ?

[suicideneil]

Even worse, he was selling them to people like that, though he had been informed by Castle that it would void the warrenty, whether he told his customers that fact I dont know...

the ERBE has a nice little two bolt mount.. it clamps it down in a small foam pad... i think thats how im going to hold down my MMM on my MBX6-t


here is a nice pic.... of the mount... LOL

[suicideneil]

Alrighty then....

[shaunjohnson]

yes i used to love that mount!, so clean and neat...
but take another look now...does it provide any give and allow to cushion blows from big stacks?

can we make it have a bit of give?
wonder if we used a locating tray for the MMM then held down with strong rubber bands and then a strong safety device?
so when you hit hard the MMM can move before being pulled back into it's locating tray?

I think most of the shock is from the bottom up.. from landing big jumps.. if you landed on the roof the shock load would be on the bracket against the ESC.

[shaunjohnson]

so those large jumps you do while racing and you cringe at before the landing...
they are the ones you think are causing the problems?
i would have though hard impacts period would have done it.
like the old "face full of downramp", the "wing bouncer" and the old classic "hard bottom scrape" would have been the culprits.
