I've been reading up on gyro precession as it refers to gyroplanes. It
seems that is not how a rotor disc works on a gyroplane. The info I've
found so far states that: a two blade rotor system doesn't tilt by
precession, but that it's entirely aerodynamic and uses vane (pitch?).
How does gyro precession effect rotor blades on a helicopter? (I could
do some research on the www, but I would like to hear someone's
opinion here first)
