Rotor Revs
Good evening Ppruners
It seems that every spec I read indicates that main rotors nearly all operate in the 400 to 450 RPM, Why? is this a speed range worked out on Strength to weight ratio's or kinetics or what, ... why not higher would a higher rev range give or offer greater safety in EOL situations,.. or is it down to size of main shaft governs highest rev limits, therfore higher revs = heavier kit ?
