MMM Mods
 
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...

MetalMan 09.16.2008 10:24 PM

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

Is that a Hyper 8?

Arct1k 09.16.2008 10:54 PM

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...

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

DRIFT_BUGGY 09.16.2008 11:07 PM

Is all that aloud under warranty?

What's_nitro? 09.16.2008 11:09 PM

Nope! :mdr:

I think so :lol:. 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:
Quote:

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.

Arct1k 09.16.2008 11:14 PM

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 09.16.2008 11:22 PM

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. :yes:

DRIFT_BUGGY 09.16.2008 11:51 PM

Anyone know if you can buy a new MMM case?

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"? :neutral:

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. :oops:
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? :rules: etc.

Any and all info would be greatly appreciated.

Thanks in advance

and be gentle:mdr:

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?
