FX,
There are many "microlight" schools in the UK that do 500+ hours a year in, basically, light sport aircraft.
They are robust! We operate off one of the less-smooth grass runways in Scotland.
We have had two taken to 1,800 hours and going strong until a hangar fire three years ago
We have two more, now at 1800 hours each and are aiming for 3,000 hours before major work (and that includes 912 engines). Touching wood.
At 3,000 hours our thoughts are to keep one as a personal hack and rebuild the other in phases over a couple of winters while keeping it in service: new engine, new wings, new fabric etc.
Scottish Aero Club's newsletter raves about the success of their Eurostar too. So it is not just me!
