    Castle Creations Statement re. XLX2 and MMX8S

    Link: https://home.castlecreations.com/bl...3YpTNQMdko6Vq-889yU8seDM7QmyZKNaZaj4cWys2VJCk

     

    "It has come to our attention that a limited number of Mamba XLX2 ESCs have experienced a failure upon plug in or while running. Most users report no problems with the XLX2 but after considerable investigation and root cause analysis, we would like to share the following information.


    MOTOR ADVISORY APPLIES TO:


    MAMBA XLX2 8S, 33.6V ESC, 20A PEAK BEC 1/5 SCALE ESC (Part Number: 010-0167-00)
    MAMBA MONSTER X8S , 33.6V ESC, 8A PEAK BEC 1/6TH SCALE ESC (Part Number: 010-0165-00)


    At this time, Castle is advising to immediately discontinue use of Delta wound motors and any motors that are 2000Kv or higher. 


    Three phase motors come in two common wiring patterns, Delta (D-wind) and Wye (Y-wind). Each pattern has its own power characteristics and Castle motors have a Y-wind design. Our current data suggests that D-wind motors, especially larger motors (40mm x 80mm or longer and 56mm diameter or larger) and any motors that are 2000Kv or higher are not currently suitable for operation with the Mamba XLX2 or Mamba Monster X8S. Running these motors can result in abnormal operation and may lead to premature ESC and/or motor failure.


    If you are unsure whether the motor you are running or intending to run is a D-wind, please contact the motor manufacturer.


    Castle is working on a firmware update that will allow the use of D-wind motors and motors greater than 2000kv. Once released, all XLX2 and Monster X 8s ESCs can be updated via the Castle Link USB programmer or B-LINK Bluetooth™ adapter to the new firmware. 

     

    The estimated availability for this firmware is the end of January 2021.

     

    MANUFACTURING AND ASSEMBLY ADVISORY APPLIES TO:

     


    MAMBA XLX2 8S, 33.6V ESC, 20A PEAK BEC 1/5 SCALE ESC (Part Number: 010-0167-00) 


    A small number of XLX2 units from the first production build could experience an internal hardware failure. Busbars that are housed within the Mamba XLX2 circuitry may, in limited circumstances, be misaligned and cause a malfunction to occur during the very first use of the ESC, whereby the ESC may beep and then stop responding.


    Anyone experiencing this type of failure is encouraged to contact Castle for a warranty service. The manufacturing lot codes of this build are C27255, C27711, and C27964. This information is contained on the label adhered to the wires on the ESC and on the outside of the product box. Note that this issue has been addressed in subsequent manufacturing runs.


    If you would like to have your ESC inspected and tested for this issue, please submit an SA2021-1 RETURN FORM and ship the ESC to Castle Creations, 540 N. Rogers Rd. Olathe, KS 66062. If it is determined that the unit exhibits this problem, it will be replaced with a new unit."

    Those were pretty bad, had at least two DOA. Also had some luck with them, still got a couple of that type either in use or in the spares bin.

    They were like £40, I had a couple in a savage, one used to clog like mad, but then I did have good one, you could buy 5 for one MMM, so it made sense 😆

    And then this was the game changer, still a bit of brick, but it was bombproof compared to everything else available at the time 👍

    My  first ESC was

    followed by the 150amp,  If you want to know if your ESC is bombproof, Just throw one of these at it.

    Only had one, BEC failed very early. Fitted an external BEC, still using it.

    The 150 Amp was awesome, only had one of those because it lasted years. Only stopped using it when the caps failed.

    We used to run them massive cheapo Hobbyking 150a escs because the MMM was so unreliable

    This is definitely not good for Castle but what I can't believe is how much some people seem to be taking glee or enjoyment out of this.  After all this hobby needs more manufacturers giving us better buying options as well as a variety of products to suit all budgets/model classes so I hope this isn't the end for Castle as it's definitely harming their reputation. 

     

    Not sure what an MMM is either that some of you keep mentioning? Never heard of that ESC OR are you referring to the Mamba Monster 2?

     

    I run the Castle MM2 retro version in my speed runner Typhon 6S and I've never had any issue with it nor my Castle XLX in my Limitless speed runner. I also have another MM2 which has been in various speed run vehicles and some more "bashing" orientated cars, ...that one I bought used and it's still going well so I've never had any issues with their products.  


    As for Kevin Talbot he still ran a high KV 6S rated motor on 8S which regardless of Castle's current statement is still against Castle manufacturer recommendations that you get on the instructions for the XLX2 as it wasn't following within the motor manufacturers guidelines. 

    Not saying that it is his fault that it went up in flames but he most certainly isn't blameless imho, but then nor are Castle. 

     

    Personally I do feel sorry for Castle but more so for the buyers and sellers of the XLX2's as this is going to be difficult to get sorted in the long run. Lot's of people now have lost more than just the cost of the ESC as well which is devastating especially for the majority of people who unlike KT aren't millionaires. 😪

    MMM = Mamba Monster Max. I used to refer to it as the 3M, I like abbreviations.

    Cool thank you. Learned something new today. 🙂

    I prefer the abbreviations too, ....well when I know what they mean that is. 😆

    Abbreviations are tight! K8 for the 8S Kraton is a great example. 

     

    As for Castle, they'll survive this no problem, their home market is huge. I'll still use them where appropriate, best drive profiles, best programming via pit-card or PC, and by far the best cell-count system (especially when they didn't cheap out and their ESCs would auto count odd cells and not just even cell counts).

    Personally I'd never own a Castle Creations system, you can pay a little less for just as much, or a little more for a lot better.

     

    Their programming is impressive, however I spent about an hour fiddling with all the settings thinking it was really cool until sticking it in the most basic: throttle means GO, brake means STOP. :lol:

    The more expensive an ESC, the more unrelaible in my experience! Bizarrely!

     

    Yeah, I think the challenges of running a high voltage in a unit so small comes with its problems.

    I'd imagine the move back to castle is largely a certain sector - namely speed runners - as the hobbywings (I'm told by a friend, one of the fastest rc ruuners in the world) throttle the power at the end of the spektrum.  

     

    I've never run castle esc's bar the odd one that came in a used rig, as when I came back to the game and brushless got affordable the consensus was castle made great motors... but less so esc's.

    Reading this response makes me feel like a right smarty pants. I definitely pointed out the wind of the motor combined with the KV 😁

    i guess castle had to come with a statement.

    too many cars burnt up and a few people reporting burns frm esc going up.

     

    i brought the xlx2 specifically for a 1/8 buggy to run 4s.

    i can run this D wind 2900kv motor on mmm

    mm2 and xlx with no problems.

     

    i doubt a firmware update will fix the issues castle speak of.

     

    And, surely the beta testers used d wind motors above 2000kv.

     

    i think ima send the xlx2 back to castle .
