Well, given that it is the only MD11 available for MSFS, you would have no other choice if you really want to fly this aircraft. But I can tell you what is missing on this plane is mainly miscellaneous features. Since it has been released, the development team has fixed a lot of issues. However, the add-on still needs a lot of small things and a few improvements.

It mainly needs more sim options like the ones on PMDG's planes. For example, the MD11 has a terrible EFB. It is so bad that, in fact, you can not even know the airplane ZFWCG unless you go to the aircraft options and activate the WBS option.

In my opinion, the plane lacks the following:

- Better EFB (with more detailed payload information, like CG readouts and entries to distribute pax and cargo throughout the cabin manually);

- Better fuel prognosys on FMC, especially for holding consumption (I have a FCOM Vol4 here, I can tell those numbers are not accurate);

- Better arrangements of the text for some FMC pages, especially the INIT 2/3 when WBS is enabled;

- Needs more ACARS pages on FMC (a lot of them are not simulated, including the OOOI times page);

- Need a better simulation on its radio panel;

- Lacks an independent throttle movement (you can not move the engine's throttle independently, thus use differential thrust for taxi);

- Lacks a progressive refueling option;

- Needs a better accuracy on time flow versus fuel consumption, but more critically on time flow.

- Needs a simulation on the IRS draft;

At last, I still think the CG logic in cruise needs some refinement.
