Notes

Modding guide not released yet, some undocumented features include overriding existing planes. You can set "Enabled": false to take a plane out of the game entirely if e.g. you don't like the Roebling becauses it's too fast.

{ "Id": "puffin.roebling", "Enabled": false }

In general, you should be able to easily override fields like this:

{ "Id": "puffin.pico", "Cost": 12000, "Capacity": 90 }
