    Help upgrading my xl2.5 on my brushed mini summit

    Hey all. I'm new to the hobby and am officialy hooked. My dad and I picked up a brushed mini summit back in December and have been having a blast.

    However we decided to up our battery to a lipo 7.4v, 2s, 25c and add an external LVD. This resulted in two burnt out esc's (xl2.5). I have been looking at upgrading to a 1/10 or 1/8 scale kit in the future. Im leaning tword the Axial exo terra kit in the future but for now I'd like to get my little summit up and running again.

    I'm looking for recommendations on an esc or esc/motor combo that will work with my summit but also be a really good combo for a future 1/10 kit build.

    Note: brushless would be fine but id like to avoid cogging because I do like crawling with the mini summit.

    The XL5 may be the direction you want to go...
    Brushed, LiPo ready, and 10th scale.

    Whatever it is I just typed... could be wrong.

    After doing some research on the internet would a sidewinder sv2 be a good choice or is the xl5 better? aside from it being waterproof.

    SV2 is definitly the better choice, however I'd spend the extra bucks for the castle MMP.

    If the SV2 is not sensored, you are going to get cogging at low speeds.
    Also, I am not sure if the SV2 can power a brushed motor??

    Has anyone tried any of these esc's? http://www.hobbypartz.com/elspcoforrcc.html they seem to be priced nicely.

    Here is the stock brushless 16th ESC specs:
    http://traxxas.com/products/parts/escs/vxl3m

    Continuous Current: 52A
    Peak Current: 326A


    You are going to want those specifications at a MINIMUM.
    I suggest getting a 60amp ESC or larger.

    Most of what I saw on your link would FRY within the first few runs, if not the first.
