Nemeth Designs had released the model as freeware and Eagle Rotorcraft Simulations got permission to update and distribute it.
This allowed ERS to add things such as bump mapping, specular mapping and self-shadows. Eagle Rotorcraft Simulations released the helicopter with 2 installers: one for FSX and one for P3D.
The model was converted by George Arana and Arno Gerretsen and it’s being distributed as freeware.
