Hi I also had a short session on the Slash11 and the Sculp9
I must say that from building quality those kites are really at top level.
CrazyFly also improved the bar, the swivel is close to the rider and the lines connection to the swivel was improved too.
there are new lines in the bar which look very High Quality lines.
I ride only 40 minutes on the slash11 and the sculp9, wind condition was 16-18 Knots
I didn't try them a lot since the guys on the beach didn't release the kites to me. (by the way i got very positive feedback from the guys who tried the kites)
but from first impression I can say that those kites are very friendly and forgiven,it took zero time to get used to them.
they generate exactly the amount of power expect from those size of kite.
stability of both kites was amazing.
turning ability is very good both kite react immediately for input from the bar with no delay.(for the C kite this pretty obvious)
I'm waiting for more windy days to check them more, but unfortunately its seems that we going to have no wind for the next 2 weeks
