Determine the proper Pitch or Module values to select the correct gear for best mesh. Typical Pitch values used in RC may include 64P, 48P, 32P, 25.4P.
Enter the Outer most Gear Diameter in mm.
Enter the Number of teeth on the gear.
The Metric Module and Diametral Pitch is Calculated
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.
