Currently, I am using Aerofly RC 7:
https://www.aeroflyrc.com
to learn fixed-wing RC flights. It is a very good simulator for visual line of sight operations of model RC aeroplanes, where the viewpoint is 1-2m from the ground close to the runway, and will track the plane, giving the same viewpoint as you would be flying a model RC aeroplane in a park or a model runway.
However, how can I set up flightgear to make it to do the same?
If it is impossible, and if a developer wants to implement a replacement of aerofly RC, then what changes does the developer need to make, and how much code in flightgear can be reused?
