One of my Bday gift got here and somewhat modded
 

Just got my Mamba Monster today and did my little MOD. Nothing special, but I'll let you guys see what I did. I noticed that the phase plugs seems to be touching the heat sink, so it might get shorted unless the space is so small that my 30yr old :party: eyes can't see. I removed a little of the plastic off the bottom of the case just bellow the fan connector. The connector is actually 1mm or so too tall and after I did it the PCB sits flat on the bottom of the case. I added some foam to the bottom just to eliminate any more movement. The top case had a problem and you can see I removed some plastic to allow the male plug to go in with no issues. I will run the ESC in my BPP with 5S and 6S powering a Neu 1521/1Y with 20T/65T gearing. I will also be running the old version of my 6S ESC Here are the pictures:

Good luck with it man! Happy bday.

Thank you.

great gift to have for a bday..!!!!!!:party:i hope that is a good unit:yes:

those bullet plugs worried me to so i did the same( still went up in smoke though)

I have a feeling this unit will do the same. They are just too close to the heat sink. From what I could make out, they seemed to be touching the heat sink. Maybe that's the problem with the Monsters and probably nobody at Castle saw it.

Happy Birthday Luciano. Hope 30 treats you well, I am not far behind you (in age, not distance)!!!:party:

My MMM V2 has a bunch of mods, but I missed this one until a friend of mine pointed it out. It's been running good for a while, but I now see that two of the motor connectors are touching the heatsink. So far:

1. Case bottom mod
2. Case top mod
3. Remove fan
4. Disable BEC
5. Run Rx Lipo w/regulator
6. Change switch to MM switch (so it doesn't turn off mid-race)
7. Rx cable opening made bigger
8. Rx cable shrink wrapped
9. Connector/heatsink contact mod coming

High maintenance little controller!

If Castle could insulate the outside of the power cups with some sort of shrink, it would help center the heat sink more precisely during the assembly process.

Your heat sink is hugging the cups on the motor side, where mine is hugging them on the power side.

Thanks linc pimp master. This is my year to shine with some RC goodies man. I just spoke with somebody and I'll soon be making a nice conversion for the great TC3. I also spoke with another person and soon I'll have my own motors too. I'll go slow as I don't want to stop putting money away for my daughter. She needs it the most you know. It should be awesome.

Let me know how your connector/heat sink contact mod goes. I almost got Dremel happy, but I don't want to mess things up.

They could 've used some sort of fiberglass insulation.

wow. ok, so your power wires are safe but the motor ones could short? as sike pointed out ours are the other way round. oculd this be the fatal error? would be an easy fix... make the heatsink have smaller cutouts :)

could that cause the instant failure??? short for a brief moment which cooks something and everything seems cool?

It can definitely cause a short. I've seen some that burned down for no reason and a short could've caused it. I have to figure something out before running it so I don't have any problem that could be dangerous.

So far, no luck. I can't get the connector off the board. The heatsink is in such good contact with the connector that I can't get it hot enough. the heatsink just sucks away the heat. I've about had it with this controller. Who's found a better alternative?

This connector-touching-heatsink issue is bad... wonder what they thought... and obvious design flaw!

Man, I'm not even going to run mine then until something can be done. I think this is proof right here from our Monsters that one of the problems are caused by the heat touching the motor or power plugs.

I hope Patrick is reading this. We are here trying to help a bit to determine what can be causing all this problems.

I do too Lutach.

I think the world of Castle and their products.

I also believe the end result of the Mamba Monster will be one of the most reliable and competitive ESC's just like the award winning Mamba Max.

I do wish Castle and Patrick all the BEST! :yes: :yipi:

Choose a Drill Bit that will fit the diameter of the wire, then drill through the center of the connector. (CAREFULLY)

Then remove what's left of the connector with a Dremel tool.

This is what I've been thinking of doing. I haven't crossed the line and voided the warranty yet though. Hmmmm...........to do or not to do?

If you end up doing it, please post some step by step photos if possible. I tend to get Dremel happy :lol:. Addicting little tool I tell you :lol:.

I was able to get shrink tubing over mine.

How much space does yours have between the heat sink and the plugs? On mine, I would be able to do that as the plugs seems to be touching the heat sink as seen in the pictures.

are you still making those escs that go up to 10S? i saw a pic of one on the traxxas forum, and that thing looks INSANE!! :surprised:

Yes, I am, but you have to wait until I get an answer from the ones who said they were going to buy. Who posted the 10S in the Traxxas forum :rules::lol:?

snellemin....it's getting alot of attention over there. it looks awsome

He sure has those guy's attention :lol:.

i think if castle hadnt spotted this issue then something is seriously wrong... im just going to keep using mine as its been like that from the start and it hasnt been an issue... dont haunt me now!

There is a coating on the heatsink. When it wears out next to two of the motor wires or the +/- wires, that's a short. Potential flames.

Luciano, you better start ordering some more. You will be getting an influx of buyers shortly :intello::party:.

I'm hoping to receive my 6S today so I can run it as hard as I can this weekend :angel:.

Sounds good Lito. I'll see as I'm waiting for more members to post some feedbacks about them. I'll be contacting the factory soon to see if they can do something special for us power hungry guys.

Regards,

Luciano.

hi

i opened up my mmm. and the heatsink is touching the motorplugs exactly like in the pics from lutach. i will obviously not use the esc until i have solved that problem. pretty sure this was one of the major sources of problems with the mmm so far.

bye

You could replace the bullet connectors with wires. But de-soldering those bullets is a major PITA, especially when they touch the HS... been there. Drilling them off is amother option.

I gave up. I thought I ruined my MMM by getting it too hot trying to get the connectors to de-solder. I ended up Dremelling a sliver of the connectors off at the point that they make contact with the heatsink. I then soldered the connectors into the partial connectors. I had about 30 minutes of track time this past weekend with no trouble. I'm also using an Rx battery/regulator and about 8 other MMM mods.

I'm not in a hurry with it. I'm going to sit back and wait until everything is working perfect with the V3. I'll be watching the ones who gets them first and wait for their feedbacks.
