Freeware F-18C w Carrier ops, A2A and A2G Simulation.
Currently at about 75% point in development cycle. They have a way to go but, imo, the FM, Avionics, Weps, Pit complexity/functionality, and Carrier launch/trap are already high realism/quality.
They are not promising but are posting possibility of release sometime in 2011.
It is a serious C model, Naval variant, Hornet Simulation.
