Good luck bro!!
But i think the best way to remove the components is to use a small hobby knife or very small wire cutter and cut all the components legs one by one.

That, what i'll do with mine if he died.

I've been wanting to try to resurrect the dead one, but I was afraid to try 'til now.

Wish me luck!

Wow! I would have never thunk it! Good luck, sounds like you have nothing to lose!

i should call then ;)

BrianG : Maybe it's just too much circuit in too small a space. Switching BECs are quite efficient (around 85% depending on load), but there is still some heat there. Maybe the ICs being used don't like any kind of heat nearby, especially since the FETs are right above it creating more heat. Or, maybe there is some inductive noise coming from the coil that is inducing a voltage in a really sensitive area.


never would have thought of that, but you know this makes alot of sense. coils, transformers, energized parts, etc.... do indeed create magnetic fields that can and WILL induce voltage onto most conductive material. do you really think it could just be a case of oh $#!* duh!why didnt we see that? like i have said before im no electronics specialist or engineer of any kind, but i do vork with high voltage. induction is real and can kill you, but at this scale all the same principals apply.

i say they give BrianG o job if he figures it out!! :yes:

That's great to know :mdr::mdr:. Now i don't have to worry about anything when I do the mod (whenever my MMM arrives).

YAY!
woo hoo. hopefully they offer a 1yr replacement for free if it stops working modded or not. im sure that the problem would be identifed quicker!

also that means they are just chucking them out or recycling parts which cant get damaged by the mod... or else they wouldnt be suggesting it at all.

Keep in mind that he said I could screw around with mine because it was already dead, and because he knew in advance that it was stock when it died. I don't want to imply that everybody can go crazy with mods.

If you plan on modding the circuit board, you should probably call first to make sure it's okay to do without killing the warranty.

I haven't had a chance yet with mine, btw. Hopefully today though.

Thanks for the clarification. If that's the case, I'll run it stock until it craps out and then call them to inform I'm doing the mod on a dead MMM. I'm hoping it will work stock though :lol::lol::party:.

Well, it didn't work for mine. I gave it a go though. Bleh. I must have fried something.

brushlessboy16 09.05.2008 06:30 AM

I modded mine and failed... they took it back even then :yes: gotta love great CS and morals

TruckBasher 09.06.2008 06:59 AM

Brian, how is your V1 doing? Well, I think I killed mine. I couldnt wait for the UBEC so I tried an RX pack. Tested it and everything checked out. After 15mins of bashing. I went to check temps, batts were ambient, motor was 130-140 but ESC was about 145-150. FANS were constantly on. Anyway, I tried again but this time there was cogging and truck can barely move. Kicked WOT and she move 2-3feet and stopped. I could still see lights on ESC and fans are still on but it just wont move. :neutral:

I took everything back and checked it via CC link and MMM still ok. Tried to connect to RX pack but now she just blink the lights no motor tones no arming...Any idea?

Hehehe I think I just made an expensive paper weight.... :lol:

kulangflow 09.06.2008 09:14 AM

TruckBasher, if you have a custom cut-off, try setting it to auto-lipo. I know that's been an intermittent problem for some of us.

Good luck!

TruckBasher 09.06.2008 10:08 AM

Yup know that...but thats not it....it seems that I killed the power going to the brain...

I am a bit concern to those who will do the mod cause it might be the long term effect of this mod....brushless IIRC had the same issue after he desoldered the 4 components...so its hard to say at this point.....

david lamontagn 09.06.2008 10:32 AM

:oh: i'am tired of all this blowned MMM.
Mine is no arrive yet and i'am scarred.
My revo is parked since 3 week because i've no controller in it, and i think that it'll parked for another somes week after my MMM test:whip:

I think that i'll save my money all winter long and try another MGM next summer, but it's not a warrentie to run MGM............................................... ..

TruckBasher 09.06.2008 10:37 AM

Its a good idea to hold on those controller at this point....I think my MMM is really just a paper weight now and rather than sending it back to CC I will just buy a new MM (unless Patrick will cover warranty so Ill just pay for shipping) :lol:

Anyway, the 2nd MMM is due to arrive next week so I will try another setup with UBEC for the servo/rx but no mod an the MMM and let its own BEC run the brains.....hopefully it will last longer...
