You think so? Hmmm, maybe I should see if I can get a 1515 1Y instead.

Here's the calculations based on the 1512 1Y:

Differential Ratio: 2.8461538461538462
Transmission Ratio: 1.8333333333333332
Other Ratio: 1
Spur Tooth Count: 58
Pinion Tooth Count: 22
Total Voltage: 14.8
Motor KV: 2750
Tire Diameter (inches): 5.65
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor coil Ω: 0.0035
Spur/Pinion Ratio: 2.64 : 1
Total Ratio: 13.75641 : 1
Tire Circumference (inches): 17.75 inches (450.85 mm)
Total Motor Speed: 40700 RPM
Vehicle Speed: 49.73 mph (79.88 km/h)
Estimated Adjusted Speed: 46 mph (75 km/h) - 7% loss
Effective KV Value: 2750
KT constant: 0.49 oz-in/A


So the adjusted speed is about 46mph. Plenty fast enough for my needs. Based on those numbers do you figure it'll run too hot?
