We are getting an 800XP in a couple of weeks. They are putting the API winglets on and I haven't seen the performance numbers on it yet. I have a coulple of questions I hope somebody can help me with. I know what API says it will do but I am looking for what people are actualy seeing. Also, we us flightplan.com. I see 3 choices for performance. The HS-125-800, Hawker800XP Int. cr, and Hawker 850XP. Wondering what you guys use if you use flightplan.com?
