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 = 8.57 FDR ** Gearing is given in rollout. Rollout is determined by dividing the tire circumference … More Information
The RC Car Gear Ratio Explained and Calculated
For every mating pair of gears in an RC car, there exists a gear ratio. The gear ratio is simply the number of teeth of one gear divided by the number of teeth of a mating gear. Gear ratios are important as they allow us to better control speed and torque. We are able to sacrifice speed in order to benefit from increased torque. This relationship allows us to achieve optimal output RPM by adjusting the gear ratio. More Information
RC Gear Calculator - Radio Control Info
Use the following calculator to determine the gear ratio of your radio control vehicle. The gear ratio calculator uses 2 combinations of gears to output an overall drive ratio. The first set is the main gear set which is generally starting at the motor or nitro engine. The next gear ratio is an internal transmission ratio or most commonly a differential gear ratio. All entered values are in terms of number of teeth. More Information
Simple Guide to RC Gearing - Radio Control Tips
Simple Guide to RC Gearing. Changing the gear ratio is an easy way to alter the performance of your RC car. You can gear for a higher top speed at the expense of slower acceleration, or vice versa. You can alter your car’s gear ratio by using a different pinion or spur gear. The pinion gear is the very small gear that fits onto the motor, and ... More Information
Understand Gearing Ratios - Petit RC
Any two gears will have a “ratio”; if your car has a 20-tooth (20T) pinion and a 100-tooth (100T) spur gear, that’s a 20:100 ratio. We need to go one step further, however, and divide the number of teeth on the spur gear (100) by the number of teeth on the pinion (20). It’s easy: 100 ÷ 20 = 5. More Information
R/C Gearing 101 — Roger's Hobby Center
To determine your gear ratio, you divide the spur gear tooth count by the pinion gear tooth count: Spur Gear / Pinion Gear = Gear Ratio 86 / 23 = 3.74:1 (This means the spur gear will rotate once for every 3.74 times the pinion gear, and therefore the motor shaft, does.) More Information

R/C 101 - Pinion Gears / FDR – HOBBYWING North America
Gear Ratio: To calculate the car’s gear ratio, you need to be familiar with the type of drivetrain it has. 2WD RC vehicles typically have a single one-speed transmission. 4WD vehicles also usually have a one-speed transmission, and are gear and propeller shaft driven or belt and pulley driven.

RC Pinion and Spur Gear Explained: A Beginners Guide ...
Any two gears will have a “ratio”; if your RC car has a 20-tooth (20T) pinion gear and a 100-tooth (100T) spur gear, the ratio is 20:100. Divide the number of teeth on the spur gear (100) by the number of teeth on the pinion gear (15). Number of teeth on Spur gear / Number of teeth on Pinion gear = Gear Ratio. 100 ÷ 20 = 5 More Information

A gear ratio of 1:8.0 means that if the motor rotates eight times, the wheels spin one time. A long gear ratio would be 1:5.0 for example. With each rotation of the motor, the car moves a further distance compared to a short gear ratio (1:10.0 for example). More Information

car) and the "spur" gear (which more often than not is found on the drive axle of a car). Pinion gears come in all shapes and sizes, as do spurs but for our example we'll say hat the pinion gear has 18 teeth and the spur gear has 90 teeth. You often see in car specification charts we publish in Racing Lines a gear ratio of 18:90. Often More Information

Primary gear ratio x internal gear ratio = Final Drive Ratio. So if your car has an internal ratio of 3.6, your equation would look like this: (64/17) x 3.6 = 13.55 FDR. This means that the pinion needs to make 13.55 revolutions to get the wheels to turn 1 revolution. The … More Information
