Actually, they are doing a project of designing and building an aircraft (imaginary) for both X-plane and FSX.
I think x-plane has a fair bit to play in this as it's the only one of the sims to allow you to enter designs and get a flightmodel back.
Will be interesting to see an imaginary plane to go with the imaginary Andreas field.
I'd like to see most of their sceneries converted, the airbusX, the twin otter and the PBY Cat. The helicopters will be good as well with x-plane flight models.
