    First time I have heard of any track allowing 4s lipos.
    Gearing is a matter of preference and if the motor will not overheat. 17/50 on 4s is on the border line. Just watch your temps.
    Fan on motor and ESC for this combo is highly recommended.

    If you put a single fan with a heatsink, you will be fine running that gearing. One of my trucks I run 22/50 on 4s! With the single fan on the heatsink, it runs nice and warm, not hot. Good luck!

    I preferred 16/54 on that motor on 4s. Never had heat issues. Plenty of torque and good speed for bashing

    In my other truck, I run 18/54 on a 3s lipo. Its m daily driver. Its just enough for me to be fun and not have to be concerned about it hitting something at great speeds. 16/54 probably is about the same way. The 2400 is a great system!

    What size shaft does it have? It came with either the 3.8mm or 5mm shaft.
