I think it is a good idea for people who like tweaking, to expose the individual vehicle configs (common\src\main\resources\data\immersive_aircraft\aircraft) to the live mod config file (common\src\main\java\immersive_aircraft\config\Config.java).

I don't mean all the options, however the vehicle properties could be good to include. For example the below from the airship.

  "properties": {
    "stabilizer": 0.1,
    "yawSpeed": 5.0,
    "engineSpeed": 0.02,
    "verticalSpeed": 0.025,
    "glideFactor": 0.0,
    "driftDrag": 0.01,
    "lift": 0.1,
    "rollFactor": 5.0,
    "wind": 0.05,
    "mass": 3.0,
    "groundFriction": 0.5,
    "horizontalDecay": 0.97,
    "verticalDecay": 0.925
  }

If this is interesting, I can also work on this and PR it.
