Hi, I'm Game Developer and C++ Programmer in Unreal Engine With 5 year experience
and also 3D Modeler and 3D Animator with 8 year experience
I worked on Flight Game before I can do that in 3 days At the required level
Edit : I have some questions, do you want the plane model and do you want the plane to be playable or Ai ?
I downloaded the map and trying to add some blueprints, I think I can finish it faster than you thought
