Delta wing planes can do the deep stall very easily, but I'm not sure about wings.

In the 3D area, you'll find an "elevator" is a near vertical descent. Some planes do it with elevator control only, others require spoilers. Altitude is controlled with throttle. You come in near vertical controlling altitude with throttle and forward progress with elevator-release elevator and you move forward. Steering is with rudder. Ailerons keep the wings level. It takes some practice, but is a fun maneuver.
