Does your 10m RPM start distorting horribly when well powered? Wingtips start flexing inwards and there is too much shape in the canopy? Mine does, but it is a 2009 model. I think the bridle has stretched rather than the material, I'm tempted to have a play with line length. It could be handy to leave at my sister's place for when I'm visiting rather than carrying gear on the plane.
Not at all. It flies and behaves the same as my less used 8 mtr. It holds it's shape even in overpowered kiteloops. As a bigger fellow the only time it distorts is when it loops while I'm in water , then it will fold up for a second. Try to avoid those brain fart failed moves!
