The final version of the Whip-Power plane that Jim Walker produced. It utilized the "U-Control" control line design that he devised for the Fireball. This patent was applied for after the Whip-Power plane had already been in production for some time.

Original Americobra design by Jim Walker in 1939, the year he developed the U-Control concept and introduced the Fireball.
During World War II, the plans for the Whip-Power were modified so you could build the Americobra or Mustang from the same kit.
