    Iam guessing the kv on the motor is to high and shuts down turn the esc back up on 2s and it rips no problems.

    do you have a temp gun?
    anytime you use a new motor or gearing combo it is a REALLY good idea to have a temp gun. using your hand to check temps is just guessing and can hurt.
    safe temp range on most motors is 160-180. for esc is 140ish. Im not sure what the temp shutdown temp is, but the higher kv motor may be causing it. Are you using a finned 380 motor or a true 540 motor? and is it the stock ESC or a higher 60amp ezrun esc?

    The stock motor/esc on 3s is really pushing it and depending on outside temps and the surface you are running on can cause temp shutdown. A higher kv motor with the same gearing (and especially if it is a 380 motor) can cause things to heat up pretty quick.

    my guess is motor kv is to high. stock motor on stock gearing is geared almost to the max. even on 2s the stock setup can thermal shutdown if you run it long enough and in sand or grass.
    Id say gear down a couple of teeth on the pinion gear to compensate for your higher kv motor.
    still, a temp gun is the only way to know for sure how things are running.


    on your 3s pack, do you run it in other models? Im just wondering if it has a bad cell which is causing the esc to LVC early.
    I haven't looked up the manuals in a while....but the ezrun manual (can be found threw google) will say what the blinking esc light means....whether it is low voltage or thermal shutdown.

    Do they have a pinion under 13t for the caldera?
