 fighter, allowing it to be carried on a trailer or even towed slowly behind a vehicle. The primary hinge for folding the wing rearwards was located in the wing root, where the rear wing spar met the cabin area. The long legs of the main landing gear contained oil-and-spring shock absorbers that compressed about 450 mm (18 inches) on landing, allowing the plane to set down almost anywhere. In flight they hung down, giving the aircraft the appearance of a very long-legged, big-winged bird, hence its nickname, Storch. With its very low landing speed the Storch often appeared to land vertically, or even backwards, in strong winds from directly ahead.

Because of its superb STOL characteristics, there have been many attempts to recreate or copy the Storch, namely in the form of various homebuilt aircraft

 such as the Pazmany Stork and Roger Mann's Ragwing Stork. Another is the Slepcev Storch designed by Nestor Slepcev. It is a ¾ scale reproduction of the original with some simplifications. The use of modern materials provides better STOL performance than the original with a take-off run of 30 m and landing-roll of 50 m with no headwind.
