Gyro's are great machines and if you had been in one or associated with them you'd realise the fun that can be experienced in them, but not necessarily dangerous fun in the right hands. Limitations in my mind are slow speed, training and fuel burn. They are a little thirsty.
Coincidentally I took these about an hour ago...
Compare the Gyro quality and design to the famous Deathranger... Admittedly the air filter is probably due for replacement.
