with the way these airplanes fly. you should not need to slip with a passenger. really. you can control yourself and the airplane to do a standard airport approach. control your speeds, control your decent, and have plenty of runway left to stop. the only time I need to slip is for MY fun. so you have it. just land a normal landing, take off with a normal take off and you can leave the flaps stationary in the normal flight mode. OFF.
