im a chinook mechanic and one thing thats annoying is that little flight it just did means once it gets back i have to do INSPECTIONS! oh god the inspections
+David Ayarra The blades rotate in opposite directions, thereby neutralizing the torque produced by the spinning blades. They can adjust the speed of their rotation and make yaw motions this way.
Mostly correct, but the rotors do not change speed to control yaw. The rotors are mechanically connected, you can't change the speed of one individually. The rotor RPM is constant at 225 rpm, its the input from the flight controls that tilt the plane of rotation of the rotor disc left or right of the fwd and/or aft head that controls yaw motion.
