Start with flight records and data logging. I returned my X-Star (not premium) today because of this glaring omission. The downloadable manual shows a flight record icon, but tech support said yesterday (Sunday, 7/17) that is for a future firmware upgrade. They further instructed me on how to acquire the flight data. Their instructions did not work. They also said, "for that the data you will need specialized software to do this which is not made available by us. The software is for internal (employee use) use."
So, if you're used to using healthydrones.com and you log flights for FAA commercial purposes, wait a little longer.
