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.
Calculate your ratio, your final drive ratio (FDR), and rollout, and see exactly how much of a difference a gear change will make.
Your RC Car manual may provide recommendations on gear ratios. A higher turn motor (13.5t, 17.5t etc) will have more torque but less top speed or RPM. Therefore, a higher turn motor will need a larger pinion / smaller spur gear combination to make use of all this low end torque.
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.
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.
14 gru 2023 · RC gear ratio calculators allow you to accurately predict speed and torque outputs to optimize your setup. Gearing depends greatly on the model’s size, weight, purpose, motor, and batteries. Experiment with different combos to uncover your vehicle’s ideal performance.
