they have.

Huh? Where.

I'am looking for too, and i can't find it anywhere

[slimthelineman]

yeah but its rated for 6s, why buy a speedo rated for 6s and not use it? higher voltage means more efficiency and lower current draw

Maybe the next generation of MMM (V5, V6.......thrue V45) will be rated for 12s, like that we could use 6s without (maybe without) any problems

[traxxasrevony]

yes but its rated for 6s and your running it at its max so your bound to run into problems.

its like taking a little 4cyl 5speed civic and running it at redline the whole time you drive.

i think david lamontagn has the right idea they need a 12s controller that 6-10s workes great on but on 12s your on your own.

i dont really see how, ran all my 1/10 scale controllers at their max (6 cells) for years with no problems. i would think the controller would like the extra voltage/lower amperage.

[slimthelineman]

plus why over rate your product why not just rate it for 4s if thats all it can handle

[suicideneil]

Fools.

MMMs have been failiing on 4s and 6s, so its not a question of voltage at all, in the slightest, nada.

When the esc pops a few fets or goes up in flames, thats due to excessive current draw, usually through a bad or weaker fet; hence the reason why any esc can go pop if you push it to hard or have an amp hungry motor.

BEC failures (the majority of issues reported) are due to something else- most likely poor circuit layout, or bad components, as has been theorized elsewhere.

The MMM is rated for 6s lipo, only limited really by a component that is rated for about 25.8v, so running 6s lipo (22.2v, or 25.2v peaked) wont kill the esc.

Not quite a fair comparison, those ESCs often have components rated at 16V or greater, or roughly twice the input voltage (under load anyways). The MMM is set up for ~25V max, and the FETs are rated at 30v. The margins in the MMM are much less, but CC had to do that to keep cost and size down.

id pay 30 more dollars to get some better fets and bec.

[MetalMan]

It'd cost a lot more than $30 at this point because of all the tooling/molds/time/money CC has invested into the current MMM. And I'm sure CC had certain goals such as price, power, voltage, etc. for the MMM which they wanted to stick to.

not so sure. becs and fets dont necessarily have to be of different size - they can be of better quality, pick of the yield etc. v2 has a beefed up bec vs v1 without any compromise to packaging.

at this point his design is fine or it wouldnt last multiple runs before failure. there are certain components - fets and becs that arent living up to the ratings that castle thinks they are buying- read made in china.

this is classic - vendor supplies samples to win the bid. they are tested and no issues. then sends 2500 of them that have 10% yield failure.
