For flyable I need the aerodynamic info for it. Currently sorting out the A.I. SFM .
The radar can be fudged together. The weapons are being done as well.
Doing some extra 3d stuff on it.
3ds max for blender - it doesn't matter, either will work. It all depends which one you know how to use. If you are new to 3d then go for Blender as it is free.
