Let me guess, its geared for 20 mph, its 6 degrees F outside and it was a 3 minute run cuz you had to come inside or your controller hand would have gotten frostbite.
...Or you bought this motor from the same guy who sold Jack his magic beans.
Somethin seems screwy... Ive never seen a MM7700 run at 115 on 6 cells in a touring car...
BTW: I'm not sayin this info isnt accurate, I just feel like a piece is missing from this puzzle.
