I will tell you one thing Autel needs to work on battery time programming . i lost like 7 minutes of flight time under 1 minute. maybe battery didnt really hold a charge.. but only charged it 12 times. uploading video guys to youtube. Will post once its done
Part of that has to depend on the conditions while flying and how the controller calculates time left. If it is basing that estimate on current power draw on the battery... then that power draw increases on the way back, because of a headwind on the leg home... there is your recalculation and drop in the time remaining.
