52mph Medusa 2000 Erevo 4s video

http://www.youtube.com/watch?v=Ji69qIoh37Y Thought I'd post this since I felt it was very impressive.All stock except electronics.I was running SPC 8000mah lipos geared 24/54 .I had to see what the motor and cells could pull.It still had alot of torque and didn't heat up to much.I kept it short though in 5 minutes of running hard the motor was 117 and the batteries were 85 thats with it about 75 out. Would someone else like to try to figure this out with the speed calculator?Because either this motor is off in the rating,The battery is holding 16+ volts under load,or I'm an idiot and doing something wrong with the calculator.
