    plan A is to use one 1000W motor for lifting and one for dumping. plan B is to use two 1000W motors for lifting and one for dumping.

    two of these in series should give me a warm&fuzzy for a Drive enable relay(s). two of them should draw .400 Amps (coil listed as 60 ohm)

    While waiting on parts for the bucket build I should think about rebuilding the current handheld mule remote controller. It's in a very sad shape.
