I have flown around 10 hours back seat in an MT-03 and a couple of hours right seat in a M24 enclosed gyro.
Have no idea of their operating costs but their utility is impressive in the sense that with such short landing and take-off distances reliance on runway wind direction is reduced. We often landed across the runway for example.
Secondly as alluded to earlier they are affected very little by turbulence, providing a stable ride but with associated highish noise and vibration levels.
Handling appeared straightforward and responsive and its a 912 pushing you along so reliability and economy come with the package.
Cruising speed, particularly upwind is however a real drag....plenty of time therefore to enjoy the excellent view from the seat !
Having said that...their popularity is growing, so clearly something is driving the market. If you are interested further, there is a large gyro population at Rufforth near York which includes pilot training and sales.
