    it does say max amps is 0! so the small wires should do just fine ;-) it must be for a (static) model

      LOL
      that's funny....

      like Alexgar said, its prolly 10Kv so it needs 220v to go anywhere meaning that it does not use too many Ah... but...
      SERIOUSLY!!!!!!!!! WTF MAN!!!! that is a huge motor!!!!!! Finding a coupler for that puppy will be a biatch!!!!

        Blackjack, I love your avatar, man! Hey, I saw those huge brushless outrunners used on a go kart in PopSci mag or similar periodical recently. They used 3 of them in line. If I remember correctly, it wasn't a speed demon (at least compared to gas), but was definitely innovative.

          As crazy as it sounds, the wife and I came up with a use for it last night. Or at least the one the link goes to at HK. I don't know that we'd actually do it, but my wheels are spinning and I've done dumber things in the past.

          We have all these small lakes around our area which are marked "electric boats only." People mostly use electric pontoon boats and paddle boats on them. We always joked that it would be awesome to have an electric stand-up Jet Ski. Well, the original Kawi 440 ski was exactly the same horsepower as the motor from HK. And it's trivial to find a dead Jet Ski with a usable hull but destroyed motor, usually free or for like $100. We're about to buy a perfectly working one for $400, they're all just old and not worth much any more.

          So...that motor weighs a lot less than the gas motor in it, but of course the batteries would really add some weight. LiPo would make it prohibitively expensive, but good old lead-acid is a reasonable possibility.

          I wonder what the cops would do, who would surely be called when you use this thing.

            I know it's not a "stand-up", but something like this?

              Watching that jet ski makes me feel like it has lead-acid batteries in it - seems bogged down some. Could really use some LIPO'S! But I (roughly) did the math and it would be cost prohibitive to be sure!

              UPDATE: Here's onehttp://www.youtube.com/watch?v=QYKE5hQnXbM powered on Lipo's and it does a little better, but still not the same as the good old internal combustion/gasoline combo...cough, cough......hack.....

                The motor isn't that big. He has small hands, lol.

                  I have seen some fairly quick go karts using a 48v forklift motor.....Lots o batteries for that kind of setup.

                        80hp is fun, but jumping from 80hp to a super charged 1800cc 250hp is insane!
