As for the 3D work, just some minor ajustments on the 3D model have to be fixed up and that should be it! See you all soon! Good news. Your 152 is one of the best add-ons for X-Plane right now.
I'm glad you guys have a lot of workers. This should reduce the possibility of having to cancel the project, and I like how you put systems first. Peter Hager did this and it worked pretty good for him.
