From the developer:
The program CalcRC should help RC modellers with settings of their RC models. The program includes extensive database of car models, AC motors, tires, servos and battery chargers. You can calculate the maximum theoretical speed of your model. The tab includes the database of models, motors and tires for easier orientation. Next to the model, you can see its picture and basic parameters. E.g. gear ratio, dimensions, weight, drive and guide price.
