As the title says, why do Hueys have 2 blades, while most others have 4, or the Sea Stallion has 6? And if you put 6 on a 4, does that mean more lift and better performance?

For a fixed radius more blades can provide more lift but more blades also increase the cost. To get more lift you need a stronger engine. Another option to ger more life is it incre
A Sea Stallion is a large heavy-lift helicopter with an empty weight of 10.7 tonnes and a max takeoff weight of 19 tonnes. It has a rotor with a diameter of 22 meter with 6 blades
A Huey is a medium helicopter with an empty weight of 2.3 tonnes and a max takeoff weight if 4.3 tonnes. It has a rotor diameter of 14.6 meters with two blades.
So to the Sea Stallion rotor need to lift 4.4x the weight of a Huey rotor. It manages to do that with 3x the number of blades and longer rotor blades.
