This triple 7 project for X-Plane is being designed by Ramzzess Aviation Design & Philipp, a designer also involved in the CRJ 200 of Javier Rollon.
While the project is still at Beta stage, there are preview materials around there like this video and more infos about the FMC preview here, and FMC calculations there.
