| Generally, a piezo gyro is
better than a standard mechanical gyro in the sense that it doesn't have any
moving parts, and it's more sensitive to the movements of the heli. However,
they are typically more expensive as well. A new type of
piezo gyro have recently hit the stores. Known as the heading lock gyro,
this gyro is capable of maintaining the heading of the heli even in strong wind
conditions and thus allowing you to fly in any direction without the head or
tail swinging about. |
