This is a new fighter airplane called KI-43 Hayabusa (Peregrin falcon) of the Imperial Japanese Army Airforce. The general idea behind this addon was not to use more points / textures as you usually spend for a single soldier. So some real big airbattles should be possible if the map isn`t too big. BRATTYS CORSAIR addon is needed. At the moment the pilot is the british pilot of the corsair package.Download file contains all the addons required for this aircraft to work, including a Corsair F4U model.
