Integration: Does it add parts that are available in the SPH or VAB, or are they only as blueprints? How well do they fit into the Kerbal universe in terms of tech tree progression.
I should mention the role of the flight model in Kerbal Space Program. Flight mods are known for their aerodynamic realism, which can be a challenge in KSP, as the game is originally focused on spaceflight. Flight of the Swallow likely uses a more realistic flight model for atmospheric craft. flight of the swallow v09113 by marinekelley fixed
Stability: Fixed versions usually address crashing issues, physics glitches, or part malfunctions. I should check if the fixed version improves on these aspects. Since it's a user-fixed version, there might be specific issues that the community found problematic in the original, so Marinekelley's fixes should resolve those. Integration: Does it add parts that are available
Also, the flight model compatibility with other mods—does it conflict with the KSP's internal flight calculations when used with mods like Kethane or Kerbal Atomics that add new fuels or parts? Flight mods are known for their aerodynamic realism,
Realism: The mod's realism in terms of aerodynamics, engine performance, and handling. How it compares to other realism mods in KSP.
If the mod includes parts like specialized engines for planes, maybe better fuel efficiency, or weapons that are more in line with historical accuracy.
Lastly, the aesthetic and model quality. High-quality textures, proper animations for moving parts like landing gear, flaps, etc., can greatly enhance immersion and usability.
