Kent, I have pretty much sidelined that model some time ago as it's graphics are outdated. The Coolsky DC-9-30 is probably a better bet but the only videos I have seen of it in P3Dv4 are by J.R. Haley and his FPS during the flight and video recording are awful so it is hard to say how well it performs. That model is very in depth systems wise but IMO was always too much for at the time in FSX and a VAS hog. I highly recommend the Leonardo Maddog for P3Dv4 and the TFDi 717, both of which are fantastic performers and in depth systems which the models are set up to where you can launch from a C&D state or RTG. In my opinion, those two models are the finest jet tubeliner models out there at the moment.
