    If a friend has one,

    • use a DC power supply to drive your motor and see how many amps is draws
    • insert a watt or amp meter between the battery and motor to see how many amps it draws (if watts, divide by your voltage to get amps)

    Then get an ESC that is rated for 1.5x to 2x that max reading.

    Or, get a cheap 20A or 25A ESC.  Test it at full throttle under load.  If it holds, buy three more.

    If you do aerobatics, get the 25A ESC.  If you burned out your ESCs, I'm assuming that you fly above normal 18A loads.

    Disk motors traditionally are quite low amps compared to a 28 or 35mm

    On 3s I think 30A will be more than ample. 4s would use less.

    My 950kv 28mm motors push 1.25kg at 4S and pull 17A
