Oh, dude, those little spinny things on a helicopter are called the tail rotor and the main rotor. The tail rotor helps the helicopter not spin out of control, and the main rotor is like the big boss that actually lifts the whole thing up. So yeah, those propellers are pretty important for not crashing and stuff.

For a helicopter to be stable as it flies it must have at least two propellers. why?
Helicopters require at least two propellers to achieve stability through a concept known as "counter-torque". The main rotor produces torque that would rotate the body of the helicopter in the opposite direction. The tail rotor or fenestron is used to counteract this torque, providing stability by keeping the helicopter from spinning uncontrollably.
