Calculation of the expected flight time:
If the quadrocopter is to carry a camera with a weight of 350 g and the battery used (3S 2000 mAh) weights 150 g, the
additional load is at 500 g.
The total flight weight is then at 900 g and the power intake according to the table is approx. 130 W.
The flight time can now be calculated as follows:
Battery voltage (11.1 V) x current (2 A) x discharge time 60 (min) = 1332 (Wmin)
(1332 Wmin/130 W) x 75% (useful capacity) = 7.68 min
The expected flight duration is about 7.7 minutes.
Flight time extension by second battery:
If a second battery (3S 2000 mAh) is installed in parallel to extend the flight time, the take-off weight increases to 1050 g
and the power intake to 162 W. The new flight time is calculated as follows:
Battery voltage (11.1 V) x current (4 A) x discharge time 60 (min) = 2664 (Wmin)
(2664 Wmin/162 W) x 75% (useful capacity) = 12.3 min
The expected flight duration is about 12.3 minutes.
The calculations refer to regular round flight.
The power emission of the speed controllers may be 3 to 4 times higher if the maximum rising output is run.
Carefully move towards the flight times that can be achieved and check the remaining capacity of the battery after
each flight to prevent deep discharge during the flight in any case. This would damage the battery and cause a
quadrocopter crash.
