The stalling speed of an helicopter blade
- does not change.
- is increased when the helicopter is heavier.
- is increased when the helicopter is lighter.
Explanation from PART66Online
A heavier helicopter needs more rotor thrust, demanding a higher blade angle of attack, so the blades operate nearer the stall and stall at a higher speed. The blade stalling speed therefore rises with weight; it is not constant, and it does not fall when the aircraft is lighter.

Blade stall is more likely when the HC is heavier. Does that not mean that the stalling speed of the blade is increased when the HC is lighter and will stall at a lower speed when the HC is heavier? Just getting ready for my A3 and this is confusing me!

no it is simple as that when it is heavy high stalling speed when it is light low stalling speed. Dont be confused my friiend.
