With the Milviz P3D catalogue now available for free but unsupported, it might be useful to pool knowledge on getting them to work...
My experience so far using P3DV5 (NB some, including the Phantom only officially support V4)

Sabre: Installs and runs, throttle not animated but works (maybe not 100% ?)

Skyraider: Seems to work fine (installs a different MVAMS utility than all the others use)

Otter: Seems to work fine

T-38A: Seems to work fine

F-100: Installs but lots of green textures in the cockpit, suggesting missing textures though can't see why - texture.cfg looks good and folders are there

Phantom: Crashes P3D after a few seconds if loaded 'ready-to-go', OK if loaded 'cold-and-dark' - not yet completed the startup sequence so may or may not crash P3D eventually

Any clues as to how to fix the last two gratefully received, and any other relevant tips/experiences.

Cheers
Keith
