Is there enough inertia in the rotor system to raise collective for landing at zero airspeed? Is there sufficient benefit in this manouvre for small helicopters to consider a compact highspeed flywheel in the rotor drivetrain?

Reason: Misused the word "flare" when meant "raise collective for landing". Thanks lelebebbel..
