    2wd slash 12t to VXL 3s

    I am debating whether or not this upgrade is worth it...

    Are there any parts you guys recommend upgrading right away?

    Specifically with the drive train?

    Worth it? Once you go brushless youíll probably wonder why you waited! As far as drivetrain the newer 2wd will usually handle it just fine, not to say you canít or wonít break anything. I would invest in some good quality lipo batteries and a charger if you donít have that already. Aluminum bearings carriers and castor blocks would be one thing that I would probably change, with the added speed they seem to be a pretty common part that can break. Otherwise just replace parts as you need them.

    I get the wb sc8....
    but the vxl 3s has a 3500 KV motor....

    why go down to 2150?

    I have a ratio of 2.72

    this would change it to 3.04...

    Why not go with the 4000 Kv motor?

    The lower Kv that you go, the more torque you will get.
    You will also get lower temps which should allow you to gear up the motor.
    You can also run higher cell batteries while still maintaining cooler temps

    Someone correct me if im wrong
    I ask way to many questions

    You are correct to question that recommendation. What works for some may not work for your goals, but that said, we don't really know much about your goals for the brushless conversion. There's reasons why you would run a low kV motor, like more torque, and ability to run higher cell count batteries without concerns of overheating. However, if you want speed and go with a low kV motor like that, you HAVE to run higher cell count batteries to get the speed (motor RPM = voltage * kV).

    On the flip side, there's also reasons to go with higher kV motors similar in range to the 3500 VXL that you mentioned. Do you want more speed without having to run at least 3S? Do you already have 3S or more batteries, or mind buying them? Those two questions are the key to narrowing the range of motors to consider.

    I recently did a Hobbywing SC8 and GoolRC 3500 in my son's 2WD Stampede and am really happy with it. We just bash in the backyard and run 2S batteries. It is noticeably faster with no signs of heat.

    batteries and chargers arent an issue...

    I want something faster.... I have an xmaxx and thats fun...

    I plan on going campng lots this summer and would liek to take both with me...

    waterproof would be nice.
