...succeeded in getting "clean" (no sidewinders or rails) to work?

This seems to get asked every couple of months ...

For some reason I can't find the umpteen threads here... searching "Crusader" isn't bringing anything up...weird
Anyway - the simple answer is not in FSX. In FS9, there was a contraversial and not-exactly-authorised mdl and alpha fix available to render them invisible - hence why Garry Russel released a number of RF-8G paints all those years ago. In FSX, however, the fix turns the missles and pylons into transparent "windows" , enabling you to see through the model, creating a problem worse than the one you're trying to fix.
That's a bummer, because, as Expat points out, it's a nice looking model. I had the privilege of being the lead QC/details/beta tester on this project with Carl, and can say it truly was a joy (and pain at times!) to struggle to put in as much detail and accuracy as was possible back in 2005. Which is why I'm ok admitting that I've since moved more onto the Rollus model - though itself also a portover, it has details that are more meaningful to me - a far nicer VC, and overall faster FPS (at least on my machine). Also, I'd suspect the flight model on the Rollus model to be more accurate, as that excellent modeller likely had access to better data than did Carl and I.
That said, I'd concede that the Alphasim exterior model is the nicer of the two, and with a huge array of repaints available (ah, remember the good old days of Pierre Llerreux?

), it makes for a nicer "screenshot model". For me, I put a bit more weight on the flying (esp carrier ops) aspect, which is why I now prefer the Rollus model. But I still keep the old AS bird around, if for no other reason than for sentimentality.
Really, I'd say if you're a fan of the "Cru", then my recommendation of whether you should fly the AS or the Rollus model - my answer would be "yes"!
Glad to see the Carl's old bird bringing folks joy after all these years! The man did a superb job, and was kind enough to personalize one of the repaints with my name, and another with the name of another SOHer - in his case, a former USMC ground crew member who worked on VMF-235s in Vietnam. Carl was a prince - and a shame he didn't model for FS for too terribly long - but what did do, was (and still is) good quality.
