Hehehe... Tallpindo... That guy's known for leaving cryptic, vague, and yet somewhat interesting comments (because one's trying to figure out what he's saying.) But he does appear to have an interesting range of knowledge. Also see if you can get in touch with BigKahuna (if I recall right - also I believe that this is Frank Chase's name here at Renderosity), because he's done some supurb mechanical modeling of engines. The neat thing about his work is that he actually accomplished it by using all Bryce booleans. Also agree a bit with ddruckenmiller on the engine. Odds are that one's going to even see less of it with the prop on there.
