I have put 17 flights on a Q40.. using the Team Orion 600mah LiFe pack.. ALL "high voltage" JR 3711 digital servos, 4 in total.. Maybe 4 or 5 minutes per flight with the radio on, that's a guess of course..
Charged the pack.. Only put about 285mah in the pack. So that was about 16.5mah per flight..
Technically you could fly many more flights.. But that was about my limit
