The Dätwyler 1038 MDC Trailer was a 1960s Swiss glider tug variant of the American Piper PA-18 Super Cub.
[1] Dätwyler had experience converting a number of war-surplus Piper Cubs for the civilian market.
[1] He used this experience to create a single-seat glider tug variant, using the wings, tail unit and landing gear from the post-war Super Cub, mated to his newly designed fuselage.
[1] Powered by a Franklin flat six piston engine, it first flew in 1960.
