reverse nuts, oh what fun, after there was a bare patch of dirt left i went for another quick wheelie before the monster stopped.
the plug in spark is next to nothing now and the castle link nearly caught fire when i tryed to link it up.

so it's in the mail to castle today, wont bother express posting it this time

eagle tree data only shows 70A peaks and reverse is limited to only 50%
i was running 6s on 40mph gearing.

i'd say the BECboard is fried.
oh well...now...spare MMM with a 1600 medusa in the slash?

That sucks mate.
A MMM of mine pulled the pin last week. Think it is the bec aswell.

Sorry to hear. But from what everyone says, Castle will take care of you, repeatedly. To avoid down time I hear alot of Castle fans buy another product for a spare.

Bondonutz · 02.16.2010, 10:33 PM

On 6s you might be way better off with the lower brake setttings around 25-30% from what I've read.

I run 5s in all my trucks and only have braking at 30% and can't understand why anyone would want more ? I think this is where some of the problem may lie ??

Still hurts to hear your having pronblems Shaun, hope Castle gets you turned around quickly !

shaunjohnson · 02.17.2010, 04:48 PM

yeah i have all my settings tuned down so you can actually utilize the 6s.
30% brake, lot of punch control, mediocre throttle/brake curve.
ive got it set up so that the wheels will not fully lock up under braking at full travel since you dont want a full lockup.

fast turnaround

it's been 2 weeks 2 days and it should be arriving sometime this week if i am luckey

03.02.2010, 03:53 PM

Congrats, sounds like a quick one for sure.

shaunjohnson · 03.03.2010, 04:39 PM

i also found the perfect switch

it's so hard to make it click over that i had to use 2 hands!
and no it isnt some huge knife switch either, its the RX switch from a duratrash nitro evader i'm converting.

..another day another MMM on 6s failure.

I've lost count!

It sounds like after all of this time CC still has some issues to work out on the MMM. Too many failure to count over the last year. I know from their perspective it may only be a small percentage, but there have been quite a few on here alone, and some of them are quite capable technical wise. How is the RX8 holding up against the MMM?

Bondonutz · 03.07.2010, 10:10 PM

FastBaja,
Sorry your havin probs again.
Aren't most of these failures 6s power related, not just yours but most failures in general ?

fastbaja5b · 03.07.2010, 10:19 PM

Most seem to be on 5 or 6s Lipo but have seen a few on 4s. I have always maintained that it's not the failure I have a problem with (things fail, it happens, thats why there are warranties) but the manner in which they fail (lots of smoke, fire, melted cases and potential damage to other components or people) and the regularity that it occurs. I know some guys on their 10th MMM! And while most "know-it-all" forum users will try and put it down to user error, that's not often the case. When you manufacture a product that is included in Traxxas Brushless Revo's, HPI Flux etc you have to anticipate a certain degree of "newbie" users and have a system that is somewhat tolerant of this.

Agreed, Most failures that I remember reading about (here on RCM) were 6s related. I know most members here are plenty savy and that their issues are certainly not user error. I'v had 3 failures over the the last couple years on
4s, none on 5s and I don't use 6s for the reasons mentioned.
My boss drives his LST2 on 6s like a complete nutcase, geared for 50mph and brakes set at 50%, ben 8 months no problem yet ?
Luck of the draw I reckon ?
Again, sorry to hear of your persistant prob.

High current devices tend to let out smoke and flames- thats alot of power in a small confined area being released. You cant avoid this small potential for collateral damage, especially when the escs are mounted to plastic trucks, but when they do fail during use, they tend to be in the middle of a track or field, so damage to property and people is limited.

Whats worse, a runway 20+ lb gas or nitro truck, or an electric truck that stops dead and smokes for a bit?

fastbaja5b · 03.08.2010, 11:15 PM

Most RTR Bajas have a built in failsafe in the radio and a provision for a picoswitch to cut the engine in the event of loss of radio signal so it's a bit of a mute point isn't it?

If any other consumer electronic was shown to burst into flames and melt in the event of a failure it would have been recalled.
