RE: Gyro in an Airplane
But if the sticks were centered and the plane was pointing at the ground its still going to fly straight, straight into the ground. If you want something correcting get a co-pilot, I really don't think you understand how a gyro works and what its uses are in an airplane.
Many scale folks put them on the rudder channel to help with ground handling.
3D folks put them on the elevator/rudder to help them make minute corrections while hovering and high alpha manuvers buy they really just correct unwanted movement, they have no sense of the direction or attitude of the aircraft.
