Yeah. I heard they are on sale now. You have the buy the Phantom cable, too.
You upload the file to their web site and then you can see all of the data. Oh, Dashware is an extra $50. That is what you use to sych it with video. Flytrex by itself lets you look at the data and flight path on their web site, export the data to a spreadsheet and export the data to Google Earth. This is really nice, you can go to Street View and see the flight in 3D. Assuming you fly near a street that is in Street View, of course.
