We did it! My son and I went to a nearby baseball field and, very nervously, achieved lift off. After hours of practice with the nano, it turned out that the x830 was far more stable (ECS, Duh..). Take off and landing are tough, but flight is fairly straightforward. Only a few puffs of 2-3kt winds at 2200 ft elevation.I'm going to spend a few battery cycles practicing here, then I'm going to take it to Vegas!
