RC Calc application contains a set of useful calculators that help in setting up and maintaining rc cars. To switch between calculators, select the desired one from the list on the top panel of the main screen. Description of calculators is given below.

Ratio Calc

FDR (Final Drive Ratio - rc car parameter which tells how much faster the motor shaft is spinning than the driving wheels), CS (Counter Steer - rc car parameter which tells how much faster the rear wheels are spinning than the front wheels), Internal Ratio (rc car transmission gear ratio excluding spur and pinion) and Rollout (distance rc car moves forward per revolution of the motor) calculator for rc cars. The application contains a large list of popular chassis and their modifications with the ability to select the desired model for the calculation. Also there is the ability to save and edit your setups.

FDR Calc

FDR (Final Drive Ratio - rc car parameter which tells how much faster the motor shaft is spinning than the driving wheels) calculator by given spur, pinion sizes and the internal ratio value. The result is displayed as a table of values. The application contains a large list of popular chassis and their modifications with the ability to select the desired model for the calculation. Also there is the ability to save and edit your setups.

Belt Calc

Belt length calculator by given pulley sizes and distance between them. The application provides a convenient interface for calculating the exact sizes of transmission elements of belt chassis. The application also allows you to calculate the exact sizes of elements of other similar devices, such as bicycle transmissions.

Weight Calc

Car weight distribution calculator by given mass values at each wheel. The application helps to determine the exact masses of all sides of the car, as well as their percentages. Also there is the ability to save and edit your setups.
