I don't know where Stein got his information, but he sure got it wrong. He said the IFLY has no autopilot interface plus several other features. I just flew to Oshkosh using the IFLY720 and my TruTrak the whole trip. I've spent a lot of money with Stein but this really ticks me off. The good folks at Adventure Pilot don't need this kind of press. I think Stein should pay for a full page ad showing all the great features.
