FSX/P3D. This is one of the things I really love about Lionheart. besides developing really high quality classic, ultralight, and high performance aircraft, I really enjoy the imaginative concepts he delivers including the Avelina among his early FS9 concepts. As we all know, Lionheart is developing (what I think is) the Aero Shark for 2015. But this render released today is his newest baby, another futuristic custom design. Sign me up for one. Okay heading back to go play with my brand new Quickie 200!
