you are currently geared for about 60 mph. The 1y is a bit much on 6s, IMO.

I would try a larger spur with the 12t pinion, if you can fit that.

Here is your setup with the 12t pinion

Differential Ratio: 4.09
Transmission Ratio: 1
Other Ratio: 1
Spur Tooth Count: 46
Pinion Tooth Count: 12
Total Voltage: 22.2
Motor KV: 2200
Tire Diameter (inches): 6.5
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor coil Ω: 0.006
Spur/Pinion Ratio: 3.83 : 1
Total Ratio: 15.67833 : 1
Tire Circumference (inches): 20.42 inches (518.68 mm)
Total Motor Speed: 48840 RPM
Vehicle Speed: 60.24 mph

Not sure if you can fit a larger spur... Something like the 62t spur off the crt truggy... 12/62 gearing will definately help, and get you around 45mph.

I have a feeling that the current draw is well over 125amps... That would explain the battery temps...
