Ok, I thought that you were using a 65t sput, not a 56!!!

Changed up the speed calc and here it is:

Differential Ratio: 2.8461538461538462
Transmission Ratio: 1.83
Spur Tooth Count: 56
Pinion Tooth Count: 22
Total Voltage: 11.1
Motor KV: 3500
Tire Diameter (inches): 7
Total Motor Speed: 38850 RPM
Vehicle Speed: 61.02 MPH

I did not use a value for tire expansion, so you must have some to raise the top speed a few mph. I am quite impressesd, what are you using to determine speed, a chase vehicle or radar? I have used both, but find it difficult for the chase vehicle to keep up! I bought a bushnell radar gun and it is much easier to use.
