    Top speed? castle 2400 sct 19/50

    Just wondering what a reasonable top speed would be for a slash 4x4 With 19/50 gear I gearing. 3s and a castle 2400 SCT combo. Did a run today and it was kinda shy of what I expected.

    I just put your info in a rc speed calculator, it said 45. Is this close, wondering if it is accurate. It is the "theoretical maximum speed"

    What tires?

    For 4" OD taped tires I would say 45mph give or take.

    Thats about right.
    How is your temps? May be able to go up on the pinion a bit more.

    If you are looking for the ludicrous speeds it takes an MMM ESC and a 1500 series motor where you can gear up and volt up.

    Im set up with a Tekin 2650kV on 3s geared 23/50 and get around 55mph. Bump it up to 4s and its pushing 70mph but not quite there. Back it off to 2s and its down to 35mph or so.

    Some of these nuts run 2200kV motors on 6s with even taller gearing.
