I want to make an drone with these motors: https://www.amazon.com/XtremeAmazing-2200KV-Brushless-2212-6-helicopter/dp/B01M3UBGU9
1: First of all, are they good? If not, could you suggest me other motors?
2: If they need 12V and their max power is 342W, is the max current is 28,5A?
3: If the max current is 28,5A/motor x 4 motors x 65% power = 74,1A?
4: If the motors take 74,1A and I have a 3000mAh battery, does this mean I can only use my drone for 2,43 minutes?
(3000mAh / 74 100mA = 0,04...h = 2,429min)
5: If yes, 2,43min is not a lot, how should I do to be able to use my drone for at least 15min without having to recharge the battery?
