I had enjoyed some of your aircraft in previous simulators. Many thanks for your work!
Sorry I can not be of much help but as per today create new MSFS aircraft seems quite difficult still there is no a free one and there are 7 payware.
There is a way of converting FSX aircraft but is far from good: https://www.youtube.com/watch?v=eADv-pg ... ightAndFun
You can try to get familiar with the program, a good reference is this conversion of the Fokker XXI from Dutcheesblend: https://simviation.com/1/search?submit= ... d&x=26&y=6
But in any case It seems that for a new aircraft only can be used few items of an FSX one.
You can ask in FSdeveloper: https://www.fsdeveloper.com/forum/forum ... vmode.155/
