Bought it, installed it, and (to my delight) flew it on a short trip in Florida! Didn't break anything, and (because I had seen the early streams) I got going quickly. I didn't exactly follow a checklist - I didn't look at one! - but the annunciator panel stayed dark, so I obviously wasn't doing anything too terrible. I even landed it nicely. I can't believe it! Coop - you've done a great job! I just used the 530s, so now I really need to study the right way to do things and get to grips with the FMS (eventually!). It just flies so nicely.
