The correct answer you are looking for is a simple one.
(From a turret)Go into auto climb, decrease power to around 70-80% and apply moderate rudder in the direction you want to turn.Drones turn better at slower speeds,and the climb helps also.
You need to be wary, as the climb will make you a slower target and thus a wee bit harder to miss, on the plus side you are also draining your targets speed, and quick escape.
