I have been converting several of my old FS9 Models to P3dV4 using the Model Import/Export function in the development ModelConvertX version. The models convert fine for the most part except most of the control surfaces do not show. Sometimes I see strange items attached to the aircraft. Also propellers show but do not rotate. I tried using the Animation Tweaker to fix but am having no luck. However, I can get doors and canopies to open using Shift E. I am a total novice working with these model files and hope some one can assist.
