Skywalker falcon first flights (so efficient you'll think I'm lying)

Banggood:
After making this video I tried a flight with a 3S 2200mAh battery, no camera onboard (AUW=634g), and got 70 minutes! This is measured from full charge until the alarm sounds (3.3v under load). The first 1/3 of the flight was slow level cruise at about 40% throttle, the remainder was mostly long slow climbs and glides. Battery cells were at 3.54v a few minutes after landing.
