The Perfect First 1/4 Scale Model
The Piper J-3 Cub is arguably the most recognizable of any light aircraft ever manufactured.
If it's yellow, it's got to be a Cub!
During the past 70 years since its introduction, the Piper Cub has probably been responsible for training more full-scale pilots than any other single aircraft in history and is still going strong today. Balsa USA's 1/4 Scale model holds up true to this fine tradition. No other Cub kit is as complete for the price. Accurate in outline, our Cub kit is as easy to build as it is to fly. A complete step-by-step photo illustrated instruction manual leads you through the construction of the model from start to finish. The hardware package is absolutely complete with over 100 items.
Laser Cut parts simplify and speed up the building process. No special tools are necessary because there are no screened parts. Easy to build and even easier to fly, the Cub is the perfect choice for a modelers first 1/4 Scale project.
The two piece scale wing design comes easily, making the model simple to transport and set up. The flying characteristics are absolutely outstanding, just like the full scale Cub
The Balsa USA Cub is a truly great kit of a legendary aircraft.
