i'm 1630g., 10x5, 4s, 3000 mah, 2814 motors, 8 minutes,,,,,, on 2215 dji motors was 10 minutes. dji max was 500 watts, 2814 hits 700 watts
when i first started out, 1600 on 3s seemed to be the max, it'd go at the ground half way into a flight and not stop, sucked. take the gopro off and whatever weight was lost was enough to make it fun to fly again.
