    third ride out on my board. the left motor gets hotter than the right especially after a few up hill climbs. same thing.

    Is it always the left side that gets hotter on these boards? Anyone with a hotter right motor? Mine was /is the left.

    here's a theory - direction of rotation of the external motor housing (against the airflow) over the board - of course if sitting static on its back this would eliminate that

    When we say left a suppose you mean the left as you see the board from behind ?? Mine is so ..

    B
    but again if I think that I tested mine without riding at all and without any belt or wheel on ... I thing its something else ... try to do tha same test and test the motors just bare ... and then try to see the temp with an infrared thermometer

    the best way to refer to it is PORT and STARBOARD - like a boat

    Port is always the left side when standing on the board (motors at back behind you) - or standing at the helm of a boat (starboard is right)

    Yes, with any moving object you refer left to right as referenced to your forward motion or your normal sitting / pilot position. Even when laying in a bed, right is referred to the side as you are laying in bed actually looking down from the headboard.

    True. But since its barely used and the majority of people don't know a thing about marine navigation it becomes more of a problem of people mixing the two up. I own a fishing boat and even I get confused at times. Only way I remember is Port is to Left for that they have the same amount of characters in them :)

    easy - "is there any more port left in the bottle" - lol - who drinks that crap anyway

    Thanks, that's easy to remember! If you make it silly its easier to recall.

    ....so back to the issue. It would be a good test to swap the motor wires on the controller. See what the heat follows. If the port side or left motor runs hotter, its the controller most likely causing the issue. You can ride goofy or change your position as another test to see if the motor temp side changes, but I doubt it since when mine heats up its typically on straight runs. And if it follows the motor, well then its of course something in the motor. Try to keep your belt tension dialed in the same using a guitar tuner and plucking the belt.

    Also you'd have to test and rule out the external motor cooling theory. But if you tape up the cooling holes for a quick test that should prove/disprove that one quickly.

    ... and to add to that - we need a baseline - whats hotter mean ? - like you can't touch the hot motor or its 5-10degrees warmer (again ideally measured with IR heat instrument) - whats normal - any other symptoms - noise - burning smell etc - I notice the belts warm up a fair bit - at least with the board in test mode on its back

    If have test it and it is from 5 to 14 degree Celsius difference depends on how much you stress the motors with hills ..
    but (again) why don't you pay some more attention to what I have already mention before . IF YOU JUST TAKE OFF THE WHEELS AND THE BELTS AND RUN THE MOTORS WITHOUT ANY LOAD , the left motor gets warmer than the right

    Yes, but you aren't paying attention to what is being suggested. Wiztec is suggesting you swap the wiring for the motor controller to see if the circuit is sending more current on the left controller versus the right. unplugging the belts and wheels won't test this. I suggested this several posts ago. Give what wiztec suggested a try to see if the temp gets hotter on the opposite motor after doing so.

    That's a good idia I LL do the swap and test it again without any BELTS and wheels ..
    but if this make the cooler motor run warmer then it's definitely the esc gives more current .. but how it has the same rpm when you test it in the advanced menu with the motors rpm for each motor ?
    Also what I have noticed is that the motor that gets hotter is the motor that the menu shows that draws less current (not big difference a slight one 0,3 amps ) ??? I will do the test anyway and we'll see then

    Honestly, i believe this may be a result of which side of the board you stand on(goofy vs regular). Just a thought.

    Explain how that would increase temps on one side versus the other? Also in the thread the board has been run with the belts off and could still reproduce the issue.
