Hi,
I am in the design process of a quadrotor helicoptor (might not get past that, lol) and I was wondering, how do you calculate the lift power of a propeller (four blades) at x diameter and x rpm?
I'm looking at a weight of 25-30 pounds, with an optimum lifting power of 35-40 to overengineer and allow for gaining height (it's a big 'un), and would need to know this to know the sizing of the rotors.
Thanks,
Mr. Ninja
