Are you trying to justify the 0.9mph inaccuracy. :005: This was a compliment.. Not a criticism. Man you are a perfectioninst. :rolleyes:


My setup. Emaxx w/ stock diffs and 2nd gear tranny, 5.8" Zombie-maxx tires (duct taped to reduce balooning), Lehner 1940/7 motor, BK12020 ESC, 5s TrueRC lipo (I assumed 3.5V/cell under load). 51T/16T gearing.

Heres the data output from you calculator:
Differential Ratio: 2.8461538461538462
Transmission Ratio: 1.7222222222222223
Other Ratio: 1
Spur Tooth Count: 51
Pinion Tooth Count: 16
Total Voltage: 17.5
Motor KV: 2239
Tire Diameter (inches): 5.8
Tire Ballooning (inches): 0.25
Motor Current Draw: 0
Motor coil Ω: 0
Spur/Pinion Ratio: 3.19 : 1
Total Ratio: 15.6242 : 1
Tire Circumference (inches): 19.79 inches (502.72mm)
Total Motor Speed: 39182.5 RPM
Vehicle Speed: 47 MPH (75.5km/h)
Effective Speed Rate: 2.69mph/V (4.31kmh/V)


I can't decide if its more fun
to make it...
or break it...


Silent...But Deadly
