Think about your basic lift theory of the main rotor in forward flight. The main difference is that the advancing and retreating blades are in completely different environments. Hopefully if you do fly helicopters you understand flapping to equality, dissymmetry of lift, flapback, inflow roll, inherent sideslip...so yes, rotorcraft are different.
