The Piper Super Cub is a bush-flying legend that refuses to stay stock
In short: Introduced in 1949, the Piper PA-18 Super Cub became an icon of rugged aviation. While it retains the simple fabric-and-tube construction of its 1930s ancestors, its high-lift wings and powerful engine allow it to conquer unimproved terrain. Today, finding an original, unmodified Super Cub is a rare aviation event.
The Super Cub emerged from a lineage tracing back to the Taylor E-2 Cub of the 1930s, yet it introduced a transformative flying experience. By adding flaps, an electrical system, and significantly more power than its predecessors, Piper created a machine capable of extraordinary short-field performance. Early models could take off in about 200 feet, and even as gross weight increased to 1,750 pounds with larger engines, the aircraft maintained its ability to operate from remarkably tight spaces. This capability made it a staple for bush pilots, banner towers, and glider operators alike.
The aircraft's enduring popularity stems from its extreme adaptability. Because the Super Cub is so frequently modified, it is rare to encounter one in its factory-stock configuration. Enthusiasts have added everything from extended baggage compartments and external cargo pods to specialized landing gear. The most iconic modification is the addition of oversized, low-pressure bush wheels. These tires, which descend from Alvin Musselman's 1920s airwheel designs, allow the aircraft to land on rocks, boulders, and soft sand without sinking or sustaining damage. Other common upgrades include vortex generators, strengthened tailwheel springs, and even custom engine swaps reaching 180 horsepower.
Beyond its civilian utility, the Super Cub served various military roles, with hundreds delivered to the United States Army and other nations. The platform proved versatile enough to be adapted for agricultural spraying, floatplane operations, and even specialized training. Over its nearly 40-year production run, more than 10,000 units were built. Today, the Super Cub remains a benchmark for bush flying, with modern derivatives like the CubCrafters Top Cub continuing to honor its design legacy. Whether serving as a cropduster or a backcountry explorer, the Super Cub remains a testament to the enduring utility of simple, robust engineering.
While the standard PA-18-150 landplane features a 150-horsepower Lycoming engine, the platform's history is marked by constant experimentation. From the early 95-horsepower variants to experimental 180-horsepower builds, the airframe has proven capable of handling significant power increases. This flexibility, combined with its legendary short-takeoff and landing performance, ensures that the Super Cub remains a fixture in the bush-flying community long after its initial introduction.
