Unfortunately no . What uasteroidsonsteroids said is probably your best bet . If you ' re looking for this information for something more than just dicking around in your spare time , you can always hunt down an aero engineer and ask them . Honestly , though , if you know the rotor diameter , start by looking for similar sized birds , that ' ll give you a pretty good ballpark estimate of lift . <| sep |> A lot of people would rather live in a world where there ' s no such thing as evil just people who are victims of happenstance and broken brain chemistry . They want it so badly they will insist against all evidence that they are living in that world . But the shitty truth is that some people with no diagnosable mental health issues , in full presence of mind , consciously choose to do horrifically evil things .
