подскажите какое передаточное число выбрать на моторедукторе чтобы скорость была нормальной.
простейшая геометрия: расстояние, проезжаемое моделью за один оборот ведущей звезды - длина её окружности 2*Pi*r Умножая на обороты выходного вала редуктора получаем скорость модели (мм/мин в км/ч думаю переведёте сами)
