Had a look and I happen to have a Feigao 14xl motor, 1191 kv. Also have a rcm heatsink/clamp...

Here is the speedcalc:

Differential Ratio: 2.8461538461538462
Transmission Ratio: 2.2941176470588233
Other Ratio: 1
Spur Tooth Count: 36
Pinion Tooth Count: 22
Total Voltage: 22.20
Motor KV: 1191
Tire Diameter (inches): 5.5
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor Coil Resistance: 0
Spur/Pinion Ratio: 1.64 : 1
Total Ratio: 10.68449 : 1
Tire Circumference (inches): 17.28 inches (438.88 mm)
Rollout: 1.62:1
Total Motor Speed: 26440.2 RPM
Vehicle Speed: 40.49 mph (65.04 km/h)

Load on the motor might be too much? Motor rpm under 30k, and the primary gearing is high at 1.64:1. Dunno, guess I will give it a try. Total weight should not be too bad considering the size.
