So sorry brother.... though I was checking, I didn't know anyone responded!! The RC Engine Redesign was put out on to the warehouse for all very early on. A second model has also been posted. I wasn't trying to cheat anyone out of anything I was just trying to finish a video with options available in pro - not available in the non-pro version. That video was also published. The whole effort was a contribution to community. Hope there were no misunderstandings. Affections
