You can read the needed current for each needed thrust == Example == The total weight of a MikroKopter (4 Rotors) is 1400g -> so each motor needs a thrust of 350g for hovering (1400g / 4 = 350g) [[ http://gallery3.mikrokopter.de/var/albums/tech/MK3538_characteristic_curve_0-8A_howto.GIF?m=1409673369 | {{ http://gallery3.mikrokopter.de/var/thumbs/tech/MK3538_characteristic_curve_0-8A_howto.GIF?m=1410791876 }} ]] Current needed for 350g with the 13x6,5 APC - Propeller? -> 1,8A Current needed for 350g with the 12x8 APC - Propeller? -> 2,4A The total current for all four motors would be 7,2A (4 * 1,8A) or 9,6A (4 * 2,4A) == Flight time == You can estimate the flight time with this formular: '''Time = 54 * Lipo / Current''' (54 because we estimate 10% losses -> 60 * 0,9) In case we would have a 3300 Lipo (3,3Ah), the Flight time for the 13x6,5 would be: Time = 54 * 3,3 / 7,2 = 24,7 min The same for the 12x8 Prop: Time = 54 * 3,3 / 9,6 = 18,5 min That is a different of 33% in flight time!
