For rollout, the calculation is:
3.14 x Tire Diameter x pinion / spur
eg: for 45mm form tires and using 30pinion 95spur, the rollout is: 3.14x45x30/95 = 44.6mm
meaning that for 1 revolution of the motor, the car will travel 44.6mm distance.
C Hing(s), is there a way to calculate the optimum gear setup to the number of turns of the motor(brushless) with respect to the power(Lipo 30C) generate?
