My truggy will beat a nitro. You should be able to beat one as well when you do find the right gearing. Here is what I got from Brian's speed calculator:

Spur/Pinion Reduction Ratio: 3.5 : 1
Total Reduction Ratio: 11.57692 : 1
Tire Circumference: 17.75 inches (450.85 mm)
Total Motor Speed: 37311.6 RPM
Theoretical Vehicle Speed: 54.17 mph (87.02 km/h)
Theoretical Speed Rate: 2.44 mph/V (3.92 kmh/V)
Adjusted Vehicle Speed: 50 mph (81 km/h) - 7% loss
Calculated Loaded KV value: 1680.7
Calculated Motor Torque: 0.28 ft-lbs
Calculated Final Torque: 3.22 ft-lbs
Calculated Motor Power: 1554 watts (2.1 HP)

I wanted to use a smaller pinion, but with my MBX5T the 14T is the smallest I can use. If you go with a 16T pinion and 49T spur, this is what you might get:

Spur/Pinion Reduction Ratio: 3.06 : 1
Total Reduction Ratio: 10.12981 : 1
Tire Circumference: 14.01 inches (355.89 mm)
Total Motor Speed: 37740 RPM
Theoretical Vehicle Speed: 49.43 mph (79.41 km/h)
Theoretical Speed Rate: 3.34 mph/V (5.37 kmh/V)
Adjusted Vehicle Speed: 46 mph (74 km/h) - 7% loss
Calculated Loaded KV value: 2550
Calculated Motor Torque: 0.17 ft-lbs
Calculated Final Torque: 1.68 ft-lbs
Calculated Motor Power: 888 watts (1.2 HP)

You might see spikes of 90A or higher which will bring your HP to 2. Just find the right gearing that works for you and take down some nitro buggies .
