Here's a pretty good explanation of the GPS vs altimeter phenomenon, at http://docs.controlvision.com/pages/gps_altimetry.php .
I'm having to learn how the Garmin in the Swift works, which is an uphill climb, but I'm OK with that. It sure beats walking! I think there's just enough room on the panel for an iPad though. There's a new sunset picture from last night at http://www.n56ml.com/sunsets/ . I got some more time in today, but will endeavor to do more Swift flying and learning tomorrow. Eventually I'll do a webpage on the differences between the KR and the Swift. In a nutshell, the Swift burns twice the fuel, cruises 20 mph slower, lands completely differently, but has a little more room inside. Bottom line is that I'm still in a big hurry to build another experimental. There's nothing like a KR, and I really miss it...
