The variant with the fan blades is a modified 727 with a GE36 Un-Ducted Fan(UDF) fitted to one side.
I know the Captain Sim 727 Captain for FSX has an UDF variant, but I don't think the FS9 Legendary 727 has it.
I can't find anything about a native FS9 727 with the UDF on google, but I hope some of this info can help.
