Try our gear ratio and rollout calculator to find the right pinion and spur for your car, whether it's Team Associated, Tamiya, Traxxas, or any other make. Enter your car's internal drive ratio to see the final drive ratio (FDR), and see the percentage change in gearing you'll get from a new pinion and spur.
Pinion: Enter the FDR you looking for ==> Please enter Spur, Pinion and Internal gear ratio.
Calculate your ratio, your final drive ratio (FDR), and rollout, and see exactly how much of a difference a gear change will make.
30 mar 2021 · You can set the transmission ratio to 1:1 value, calculate the ratio based on transmission gear sizes or manually enter the ratio if it is already known. It is presumed that the transmission consists of 3 gears.
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.
Use our RC gear ratio and rollout calculator to find the right pinion and spur for your car. Enter your car's internal drive ratio to see the final drive ratio (FDR), and see the percentage change in gearing you'll get from a new pinion and spur.
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.
