My flight time is about 10min and I only put enough batt for the current draw. I need 2 whatt meters in parallel to check the current above 70a but i expect around 90-100a at full throttle. You can setup to draw max of 60a. You will prob use 20x10 prop to achieve that. If you want to hover at 1/2 throttle you will need to use 22x10e prop. 20x13e will work too but too fast and not enough thrust.

At 90amps 4p (8000mah) should last about 5min full throttle.


My funtana 90 uses 9s2p (4000mah) with axi 5320/28 and I get about 10min flying time.
