The architecture of the game allows the intergration of new models or textures. Such a texture is the Hellenic Army Avation texture for the HoverControl Huey.The texture can be downloaded on http://www.hovercontrol.com .The ID ES 621 comes from the Ellhnikos Stratos 621 (Hellenic Army 621). With this helicopter i had some unforgettable experience in the early 90's.
