How much power does hovering require at a minimum?
Fit the components, then test the mechanism.
In hover the rotor must push down enough air to balance weight. A larger rotor disk reduces induced velocity and the ideal power requirement. The tail rotor reacts against main-rotor torque.
Ideal actuator disk in still air, out of ground effect. Power is a lower bound: profile, transmission and tail-rotor power omitted; not flight performance.
Balance 600 kg with enough ideal shaft power.
Balance weight with enough ideal shaft power.
