Simple Phase Lag Simulation in Helicopters to understand the phenomenon of Phase lag in Helicopters that occur due to the Gyroscopic precession enabled due to Rotor Movement. Press P to enable or disable Phase Lag Press C to change the rotation of the rotor blades Press Left, Right, Down, and Up arrows for movement The Arrow points towards the direction of the arrow keys pressed Phase Lag can not be enabled or disabled in real life while the rotor blades are spinning. This is only used as a learning tool for students
