For those that haven't visited FSDeveloper recently, there's a nifty little freebie that converts mdls to static aircraft for scenery development......

Not really. You can use SAMM to convert an aircraft model into a static model and then use ModelConverterX (also available from FS Developer)to convert the static model to a true FSX one.
I have been using both programs for a couple of weeks now and they work well.
