Hi rc-rodeo...I know you are a great programmer and enjoy the many planes you have created[sm=thumbup.gif]. I have tried the suggested modification in AFP and it is a hit or miss situation. If the plane is truly vertical or slightly tilted to the rear at the start of the slide it fails. Slightly forward and it works. True vertical is difficult to see[X(]. I have made it work using a word processor by making the elevator propwash values small negative numbers. I have to sneak slowly at low throttle to elevation because it reacts in reverse as the throttle is increased. It can be done well enough to fool someone on a video if only the slide is shown. The real fix is to fix the engine of the program and not the planes. Anytime I modify a plane to do a maneuver, it degrades another maneuver just as with real models[sm=idea.gif].
I was not going to post to this thread again however I don't think this is a good solution. I don't have Deluxe to try it with. I do know that in AFP that the plane reacts more correctly in the slide as the propwash decreases toward zero? All control surface values in the physics engine need to act in reverse when it senses the plane is moving backward. Only a guess on my part?
Outside of this quirk I think AFP has the best physics of any simulator I have tried. I haven't tried Reflex[sm=bananahead.gif].
