Developer A2A Simulations has released their updated J-3 Cub for Prepar3D. Announced in May 2019, the update brings their J-3 Cub to the now standards for P3D V4. The most notable changes are the use of PBR materials, a new 3D virtual cockpit and new flight dynamics.
The J-3 Cub is a basic trainer first introduced in 1938. Its latest iteration, the PA-18 Super Cub, ended production in 1994. Almost 40,000 of them have been built. Many ultra lights and amateur aircraft builders have since produced imitations.
