I'm pretty sure that the L-1011 for FSX worked fine in P3Dv2. You would need to look through the 1011 Captain (FSX) - General forum to see if I had any problems when using the FSX version in P3Dv2, and what those problems were.

EDIT ([timestamp=1426226228]): Just testing the 1011 Captain for FSX in P3Dv2.5 (in Windows 7). It shows up fine (the landing gear is visible). BUT...
The Battery Switch doesn't work
The EP shows that it's available on the Simicons panel, but is not available in the VC (EP Switch does nothing).
The APU can't be started.
Without those, there is no way to do anything in/with the L-1011 except admire the aircraft. :(
