This fun toy, or should I say "tool", has taught me a lot about laminar vs. turbulent airflow areas in places where I fly. It flies like a mini paraglider and can help you explore the safe edges of things like angle of attack and loaded vs. unloaded wing overs. Certainly it's a "must" to spend some time using one before heading out into shark infested waters on a kite board kit, but I think it works well to reinforce some paragliding concepts too!
