Gaui Quadcopter Kit 222003 Hoja De Datos

The quadrocopter can be easily flown with a 2-cell LiPo rechargeable battery with 1400 - 2000 mAh. If, however, the take-

off weight is above 900 g, a 3-cell LiPo battery should be used. The following table offers an overview of take-off weight and

power intake to select the matching battery.

The quadrocopter weight without battery is about 670 g.

If the quadrocopter is to carry a camera at 350 g and the battery used (3S 2000 mAh) weighs 150 g, the load capacity is 500

g. The total flight weight is then at 1170 g and the power intake is approx. 141 W according to the table. 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/141 W) x 75% (useful capacity) = 7,1 min

The expected flight duration is about 7.1 minutes.

If a second battery (3S 2000 mAh) is installed in parallel to extend the flight time, the take-off weight increases to 1320 g

and the power intake to 167 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/167 W) x 75% (useful capacity) = 12,0 min

The expected flight duration is about 12 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.
