Piper J-4
The Piper J-4 Cub Coupe was a two place side-by-side version of the Piper J-3 that was built between 1938 and 1942 by Piper Aircraft.
J-4 development
The fuselage of the J-4 was wider then the preceding J-3 and the aircraft had a fully enclosed rear decking to the fuselage top.[1] The first J-4s had a Continental A50, with up exhaust, an open cowl, oil and spring landing gear, a modified tail wheel system and many other changes. The early J-4 had a comfortable cockpit but was slower than most side by side aircraft of the day.
The 1940 J-4A gained a full pressure cowling, A65 engine, and aft auxiliary fuel. The J-4B was fitted with a 60 h.p. Franklin 4AC-171 engine.[2] The final version was the 1941 J-4E which sported a 75hp Continental engine. The main fuel tank was moved to the wing along with a header tank and it also had a redesigned interior. Performance was now on par with other similar aircraft of the day, but the attack on Pearl Harbor sealed its fate.
Some J-4s had another unique feature in the tail construction, the stabilizer was made of stainless steel tubing, riveted together with gussets. The plane was Piper's first side-by-side, which made it a good trainer.
