    about to be a new summit owner! need some advise

    hey everyone, so yeah, im going to buy a new 1/16 summit vxl, brushless of course, and was just wondering if there are any upgrades I should get, or if they are even needed... I already have a merv, and use it mostly for offroading, but find it overheats quite quickly unless its going fast! lol so i figured, why not use the merv for speed, and get the summit for offroading. Is the summit much better then the merv? I know they are basically the same truck, only the summit is higher, and is geared much lower then the stock merv. Do they still overheat while crawling? or is the summit basically a glorified merv?

    Summit = MERV with higher suspension, bigger tires, and lower gears.

    The one thing I inform every 1/16 owner: shim your bulkhead!

    (being a MERV owner already, I imagine you know that)
    Whatever it is I just said... I could be wrong.

    You will find they take a lot of the same parts... so yup, the same shims.

    Only differences:
    rockers
    rear arms
    body mounts
    body
    tires
    no wing
    Whatever it is I just said... I could be wrong.

    First thing to do is definitely SHIM the rear diff, or at least check it before running.

    The first thing i would say to upgrade to run reliably is to upgrade to cvds, the axles will eventually give

    Axle shaft upgrade.

    FYI:
    Stock MERV shafts are stronger than stock Summit shafts -- and cheaper.
    Whatever it is I just said... I could be wrong.

    Get the MERV drive shafts when you get your mini Summit. You will break a stock Summit shaft within the first few runs. Just replace them as they break. I'm also hearing good things from the steel MERV CVD's. The part number is 7151X. Below is a link to a picture of them. Kinda expensive though

    I would think about some way of cooling the motor and esc if you plan to run two batteries in series or LiPo batteries. I only ever run a stock batt in mine because its plenty for what I do but I did notice some extreme heat when I ran two stock batts in series. The only other upgrades and preventative measure have already been listed above. Good luck
