Initial flight was 4 minutes to see how things were going. Batteries were recharged following flight to the tune of 2800 mils per pack for the four minutes. Flights of up to 6 minutes are available with throttle management. I love to beat the patch at full throttle so I try and set counter to 5 minutes and be on downwind leg for full stop landing when the time is up. I'm bored any how after that and ready to land. I'm old and jaded. ed
