Sounds like a lot of custom work. Makes me wonder how the editor will see the map (I assume the 180m limit is disabled there). I'm most excited to fly around and see the opportunities for mission building. Also the above comment regarding the AI - but that can be worked around - is somewhat of a good question.
Most developers would release a 'pre-release' version by now. Do you have a ballpark when it comes to the release date? I can see you want it to be quite polished, but are we at least saying 2022?
Many thanks!
