I just completed the Discover Alaska Bush Trip. It was a long haul - 2,146 NM and 17+ hours over 21 legs. The scenery is beautiful and varied, so it was worthwhile. The system worked worked well with no issues related to not getting credit for completed legs. I used Little Navmaps for navigation and downloaded the Alaska elevations for it. Some challenges included getting around Mt. Denali at 16,000 ft. and avoiding prop strikes on landing the XCub, especially on short runways.
I have the Little Navmap flight plan and my own nav log.
