Rc Car Gear Ratio Speed Calculator
Final Drive Ratio Calculator - Reedy Race
By making changes to your spur and pinion gears, you can influence your car’s speed of acceleration and top end speed. The larger the final drive number, the faster the acceleration. The lower the number, the more top end it will have. 1. To figure out the final drive number, do the math: Spur Gear ÷ Pinion Gear = Gear Ratio. 2. More Information
Gear Ratio - Gear Chart - Table de rapports - Petit RC
Using standard-sized tires to calculate your FDR, first divide your vehicle's spur gear by the pinion gear, then multiply that result by the internal drive ratio of the car. The internal drive ratio can be found in the documentation that comes with your vehicle. EX. (72 spur ÷ 21 pinion) x 2.5 internal drive ratio … More Information

Many racers will have lower FDR than shown above but the above is a good starting point. Touring Car drivers warning! - if you have found your way to this page from another site and you drive a 4WD touring car then add 1.0 to the above gear ratios eg; Silver Can Brushed becomes 3.7+1.0=4.7:1. 4WD cars put more strain on the motor and therefore must be geared higher.

As long as you have all the numbers you need, just use a gear ratio speed calculator. The math is simple, just boring. The trick is grtting the actual speed correct. I like to divide the theoretical speed with the motor efficiency and I tend to calculate motor rpm from 75% pack capacity. So get these numbers and use the following calculator ... More Information

Finding the right gear ratio can change everything! I go by the recommendation for my motor in an awd touring car. Then play from there to make sure I am not overheating the esc and motor. To figure out FDR you need to calc all your gears and pulleys. 1 take rear diff pulley and divide by center pulley. ie 34/20=1.7 More Information
How To Choose RC Gearing Correctly – RevvingRCs
The MMPR calculations get more interesting on a nitro-powered car fitted with a multi-speed gearbox. On these RC cars you need to calculate the MMPR for each available spur/pinion combination, and then decide the engine revs at which the gearbox should change from one … More Information
The Proper RC Car Motor Gear Ratio Setup and Its Effects ...
Why we need to know the gear ratio calculation. As the gear ratio gets smaller, the speed goes up. For example, take Tamiya tt02 as an example. Its stock pinion gear is 22T and stock spur gear is 70T, then as soon as you replace the 22T pinion with one of 25T, the speed should go up as now the gear ratio has been decreased from 3.18 to 2.8. As ... More Information
