US aircraft manufacturers started to design a multipurpose aircraft model Piper J-4 Cub Coupe in 30-ies of the last century. Design of the aircraft was carried out from aircraft manufacturers «Piper Aircraft Corporation» on the basis of the model aircraft Piper J-3 Cub, however, the aircraft was beautifully optimized in view of what has become a very popular, although it has lost some of its operational properties.

At its core, the most important change to the Piper J-4 Cub Coupe compared to the Piper J-3 Cub is the redesigned cockpit, which has become wider to provide a more comfortable environment for the pilot and passenger. Nevertheless, this factor led to the fact that the aircraft lost the ability to carry cargo on board, however, despite this fact, the aircraft model turned out to be very popular - for the entire production period, which lasted from 1938 to 1942, it was built 1250 aircraft of this model.

Despite the fact that the fuselage of the aircraft Piper J-4 Cub Coupe became wider active factor hardly affected drag during flight, as to some extent improved aerodynamics top of the aircraft, and adapted airfoil enabled aircraft to remain as maneuverable.

The first flight tests of the aircraft Piper J-4 Cub Coupe underwent in May 1938 years - since in essence the aircraft fuselage structure has already been successfully tested, the new test did not cause little or no difficulty, and in August 1938, this aircraft was sent to the serial production. To date, it remained very large number of aircraft of this model, thus, most of them continue to be operated by private owners.

In the cockpit Piper J-4 Cub Coupe multipurpose aircraft can accommodate up to two people - a pilot and a passenger, and, despite the presence of a sufficiently large volume of space, due to aircraft equipment very low-powered power plant, the aircraft can not be used for the carriage of a larger number people or extra payload, but, along with this, aircraft manufacturers managed to keep a very reasonable cost of the aircraft.

The power plant of the aircraft model Piper J-4 Cub Coupe apparatus represented by a single piston engine aircraft grade Lycoming O-145-B1, who having thrust in 65 hp (Depending on the modifications) provides the ability to perform the aircraft at a speed of overshooting 160 km \ h., With a maximum possible distance to their sequence 545 kilometers.
