MMM Mods

[Arct1k]

I decided to do a few pre-emptive mods to my MMM.

- Removed switch
- Wired for external BEC
- Re-routed fan wire outside of the case to stop it rubbing and added some shrink
- Enlarged RX cable opening
- Removed top of fan cowl
- Added a 2200uf 35v cap
- Removed the centre of the base and added a lower plate to increase PCB clearance.
- Mounted on foam and soft velcro

PS the switch was cleaned up from here and just bridged on the PCB in the end...

I love it,You turned your moster into a MONSTER.So that was A never ran unit?

Looks good! Let's just hope this mod pays off.

Is that a Hyper 8?

[Arct1k]

Hyper ST Pro - I put two packs through it at the weekend with the UBEC, No Switch and Cap - The other mods were completed tonight...

[George16]

Why even install the case? How about just using the cutout bottom part of the case?

Is all that aloud under warranty?

I think so . CC just said that only circuit board mods void the warranty. I think it was Bernie who said that in a post.

Here's what he said:

PLEASE BE ADVISED, ANY MODIFICATIONS TO CIRCUIT BOARDS ON ANY CASTLE CREATIONS PRODUCT, WHETHER OR NOT THE ESC WORKS, VOIDS THE WARRANTY. IF A CASTLE CREATIONS ESC STOPS WORKING AND IT IS LESS THAN A YEAR OLD AND IT WANS'T ABUSED IT IS UNDER WARRANTY. IF THE ESC QUITS WORKING AND YOU MODIFY IT IT THE WARRANTY IS VOIDED. THE MOD SHOWN ON THIS THREAD PROBABLY WILL NOT WORK FOR MOST PEOPLE BECAUSE IT TAKES SPECIALIZED EQUIPMENT AND SKILL TO REMOVE COMPONENTS FROM OUR CIRCUIT BOARDS. WE USE LEAD FREE LIQUID FLUX HIGH TEMPRATUR SOLDER THAT DOES NOT WORK LIKE LEAD TIN FLUX CORE SOLDER. THIS MOD ONLY WORKS UNDER CERTAIN CIRCUMSTANCES AND IN MOST CASES ONLY DAMAGES THE BOARD OR LIFTS COMPONENTS ON THE OPPOSITE SIDE OF THE BOARD.

[What's_nitro?]

Nope!

[Arct1k]

Well technically no PCB mods apart from the switch so a little on the grey side of the warranty... If it fails due to the lower case mod then its my issue - If the BEC components give out then really nothing to do with what I've done...

I still want a bottom on the case for dirt, mounting and to protect the pcb.

[sikeston34m]

Is the pcb now tight in the case or is there some room for shifting?

The fan plug taking the shock from resting on the bottom of the case is a very valid point in my opinion.

It does make sense that mechanical shock focused on that point will cause problems.

I wonder if there is enough material to just hollow out a deeper spot for the plug to have some head room instead of removing a window from the bottom?

Nice Mods. I think you will be pleased with it.

I just removed about 1/2 the thickness of the case bottom below the coil and the fan plug. I also plan to add some heatshrink to protect the fan wires inside the case. I may remove the top like Arct1k did, as I can hear the fan rubbing the top sometimes...

Where did you get the cap Chris?

[DRIFT_BUGGY]

Anyone know if you can buy a new MMM case?

Can someone school me on something?

I am assuming that This;

If a resistor was important, (or even desirable) we would either include it, or recommend it.

I am assuming this is different...

the difference between a "resistor" and a "cap"/or "capasitor"?

Is the cap used to help reduce the electrical "ripple" effect talked about in other threads?

Is this used to help reduce problems caused by "cheaper" batteries?

I apologise in advance for my ignorance.
If you dont feel like schooling me, I understand, but maybe you can point me in the right direction to school myself on this?
Websites, links, forum threads about this subject I may have missed? etc.

Any and all info would be greatly appreciated.

Thanks in advance

and be gentle

Hi,

While I'm no expert, I think the resistor thing & the cap thing are 2 different things. The resistor thing was an attempt to eliminate the sometimes frightening spark when the battery is connected to the esc while the capacitor is there to assist the esc run a little cooler.

Hey Arct1k, if u do find the cap helps with esc temp. do update us although I think MMM is fine without it. Having said that cooler is always better.
