    70mm WTC

    Good morning all.
    I have a 70mm WTC that I got from Bob.
    I like to find the Max current draw for the Drive motor and the Max current draw for the Pump motor.
    Thank for any help.

    Simpe: put an Ampere meter in series with a motor cable (observe polarity!) Then grab the motor shaft in the jaws of a pair of pliers (old Filipino joke in there somewhere) -- put a rag around the shaft first so you don't scar it with the jaws. Go to high throttle on the ESC -- or hard-wire the motor directly to the battery source -- and read the current with the motor stalled.

    Take your reading.

    Done.

    Duh!
