I have always been a little curious about Gyros.
Recently, one of my clients (a 1950's 22 Sqn pilot) scared himself in his Gyro. He sold it to one of my (more adventurous) ultralight students, who proceeded to get lessons in it.
I dunno what happened but but $17,000 and 3 months in hospital down the track, the "new" owner of the now decidedly "used" gyro is walking again... but will never fly again due to the damage to his spine.
Decide for yourself but MY curiosity has evaporated.
