Doubts to make an helicopter
Hello, I'm doing a helicopter for two persons with a friend, but I do not know how to calculate through the power of the engine, the performance of the propellers depending on his radius.
In short, what I want are the two formulas that relate these two variables that I need to make a table testing with different engines and different measures of the propellers (apart also if it is possible to also take into account the number of propellers).
I do not know if I explained well...
