Don't know about the XLS but generally agree with the above. Very good power to weight ratio. More limited by landing distance than take-off distance, especially for public transport. So unless you have a very displaced landing threshold, if you can get in you can always get out at virtually any weight. The unfactored landing distance for max landing weight sea level ISA is about 970 metres. If the approach angle is >3.5 degrees, the figure drops to around 890 metres. For public transport multiply by 1.67.
Cavernous hold but unpressurised.
Enjoy. I do!
