Евгений, определитесь что есть для Вас “тяга”. Это быстро летать, но плохо висеть или хорошо висеть, но медленно летать. Калькулятор в этом посте дает вполне приличную точность для статической тяги. Можно пользоваться. С динамической сложнее.
Практика показывает, что надо пробывать вживую на модели. Нехватку тяги, или ее избыток, можно корректировать не только размером/шагом пропеллера, но и вольтажом и токоотдачей источника питания
Всем спасибо и отдельно каждому! Разобрался во многом. Программа по ссылке от Андрея Белякова просто супер!
