My MMM needs to go in for repairs

Doh!!!! Well what happened is that the email was delayed for a couple of hours for what ever reason. Not sure if it was from Castle side of things or Hotmail account on the fritz. Don't matter either way really as it came through eventually and from that point it couldn't be more straight forward. It's on it's way to Castle now so looking forward to getting it back.


Anyway to the Castle techs, it seemed like my MMM stopped for no reason. At first only the BEC seemed to work but no throttle input. Tried calibrating it till I was about to pass out and that did nothing. Hooking it up to the CC Link did nothing and the Link didn't recognize the MMM at all. Anyway next day I tried to plug the batteries again and this time I got nothing. Not even the LED on the ESC and no power to my Rx. What could possibly cause this? I did take the casing apart to have a looksy inside but there was nothing obvious to me. No scorch marks or funky smells.

The servo I am using is a XP1015 and that is the only thing that the BEC is powering other than the Spektrum RX. What really annoys me is that this ESC has seen bugger all use. It has sat in my Shelf Queen Revo for about a year and seen no more than five outings on a sunny day. I filled out a Non-Warranty repair as the ESC has just gone over a year old (I think) but a little disappointing to see it die in such a manner with so little use. I have other Monsters that have been used, abused and still going.

Any insight as to what might have caused the failure or is it just one of those things?

Maybe it died of neglect...

I probably should have updated this earlier . Anyway got a new ESC back within the month. That is counting travel time in both direction so that can't be bad at all considering I am on the other end of the world.

ESC is new stock and pretty happy with that. However I am having a slight issue with the BEC it seems. I pretty much run ACE1015 or XP1015 (same thing really) servos on most of my buggies and truggies. I have swapped a few around just to eliminate the servo as the potential problem but it really sems to be the BEC. If I flick the servo quickly from left to right or have the car on the ground with the suspension fully bottomed out I get huge voltage drops in the BEC output. So much so that my Spektrum Rx will brown out and take couple of seconds to reset.

I really can't be stuffed sending it back to Castle but instead I just fitted one of their external BECs and everything seems rock solid. I wish that Castle would make the MMM without the BEC and with soldering posts instead wires coming from the boards or the plugs. Maybe they could call it the MMM Pro. I think it would appeal to the more hardcore guys. A lot of us that use this ESC are running them in pretty big trucks and the servos needed in them are pretty hungry so external BEC would be the way to go anyways. Secondly lot us are doing pretty custom installs/conversions. Having a choice how we route the wires would be great.
