Then the dang thing shouldn't be rated for 6S and claim to handle "more than you can throw at it" Give me something to go by and to work WITHIN.

I agree with gearing for a bit more speed on 4S, but again, you start to deal with heat issues.. and running 55 more than a pass or two is .. for the most part.. Boring. It's not like you can really drive it around at 55mph. We can;t even really keep tires on them over 45ish without taping, gluing, re gluing, re gluing, etc...

As I said. My attempts with 6S were merely for a run or two geared up as far as I thought would be safe to keep the heat off the ESC. Even then.. I never opened up the throttle. You can't.. #1, torque is insane and won't keep rubber down. 2. Ya run out of space fast if you try and feather the throttle. 3. even if you have the space.. the radio distance will likely limit you.. or your eyes will.

Just out of curiosity, how long were your battery leads (from the battery to the ESC)? Schulze ESCs had a huge problem with this, and their manual actually said to add capacitors if the leads were long enough (because of voltage ripple).

I think Artc1k is onto something, that the MMM needs higher capacitance. Anybody know what capacitors and how many the MMM comes with?

Stock setup is 390mfd 35v capacitors. 3 of them

Funny, I just added a 2200mfd 35v capacitior to my V2 last night. The easy way to do it is just take the battery leads and solder it to the sides of the bullet connectors on the battery lead wires right where they plug into the 6.5mm sockets on the board. Thats as close as you can get them without actually soldering on the board and voiding the warranty.

I'll try and remmeber to take some pictures tonight.

Maybe 6 inches?

I certainly can't disagree with what Arct1c is saying of jhautz is doing.. Adding a capacitor to smooth out the voltage would work.. but why are we having to add components to a piece of electronics that claims to be able to handle what we are using it for??????

This whole conversation isn't to argue what I did wrong or may not have done wrong. To me.. it is looking at what I was doing that caused the catastrophic failure of the MMM. Was I within specifications? I think so. if I was borderline... then I could see a failure if I pushed too hard and for too long. Running the gearing I ran, on smooth pavement, for less than 5 minutes.. never getting to full speed, never stomping on the throttle or break... should NOT have caused it to flame. Considering when it blew.. It as rolling at a walking pace... otherwise.. I'd likely have a melted car and not just a burnt ESC.

I do agree that the MMM has been quite a disapointment... I just hope that they figure out what is up with the recent failures. Your sounds like a fet failure, those do happen, and not that frequently.

Jeff can you point me at those caps - I think I'll do the same - It worked a charm on the MM's

Dont let any of this bother you. There arent many that seem to be able to make these MMMs run for very long. I've been through 3 already myself.

Either of these should work. I used the Nichicon. Same one I have been using on the R1Pro.

Thank you - That needs to be stickied!

I ordered 14 while I was at it as the same price as a couple of Novak 4s ones.... thx

14!!!! Thats gonna be a hell of a spark when you plug it in . lol

Well I have 4MMM's and my Q125 also only has a 25v one so I might upgrade...

You can't have enough spares -

While the MMM may still have issues, there is a big difference between a simple failure and a fire with meltdown. These are two different things happening here. As well there are specs listed for it here:

http://www.castlespecialprojects.com...ntrollers.html

I do not think all failures can be lumped into the same category as many are trying to do. My V1 failed and my V2 is holding up fine.

And up to 300AMPS in Burst (10 Second/1 duty cycle)
so.. again.. I am not out of spec..

Guys, I think the Neus are asking alot of things from the MMM.
I'd try the Mamba Monster with a LMT motor.

Yah know - it might be the opposite. I had a great 1/8 buggy setup on 5S with the MM and everything was all nicely in spec and temp ranges. As soon as the MMM came out, yes the buggy had more power and accel and speed - but - first run the Neu was hotter and the lipos were so toasty I was afraid they would puff.

It's an unexpected benefit of such a low resistance esc, but at the same time it's such a difference that it'll catch you without even knowing it.

Am I the only person here with my same original 2 V1 MMM's that hasn't had a single problem all summer?? I can't believe that. :oh: I haven't modded a single thing and have pretty much run the only on 6S with the BEC......
