Create Aeronautics Lift Patch
Create Aeronautics Lift Patch changes how the Sable physics mod calculates lift and drag for Create Aeronautics aircraft, so lift grows with the square of velocity instead of linearly.
What it does
The patch replaces the linear lift and drag calculation with a quadratic one that scales with velocity. Under this model a wing produces much more lift at speed, so builders can use less wing area for both large and small planes. Coefficients are adjustable in the ldfix config if they prove a little off.
The patch needs Create, Create Aeronautics and Sable to run. It is a NeoForge mod for 1.21.1 only, and it runs on client and server, so the server and every player need it. Original physics code belongs to the Sable team, and the mod is released under the MIT License but is not open source.
Excessive lift is a documented problem with copycat sails, which carry an extra multiplier from their own mod. A scalar in that compat mod's config offers a workaround.
Key features
Quadratic lift model
Lift is calculated as a quadratic function of velocity, replacing the linear curve used by Sable.
Quadratic drag model
Drag follows the same quadratic approach, so both forces respond together as an aircraft speeds up.
Adjustable coefficients
The lift and drag coefficients can be edited in the ldfix config for players who want different handling.
Copycat sails workaround
A documented scalar change in the copycat sails compat config reduces their excessive lift.

Use cases
Smaller aircraft
Because less wing area produces the same lift, builders can design compact planes that still fly.
Who it’s for: Builders of Create Aeronautics aircraft on NeoForge 1.21.1 who want wings to generate lift at higher speeds. Server owners need to install it on the server and on every client.

What the author says
Changes the Sable lift and drag calculations to properly calculate it as a quadratic increase with velocity rather than the linear it currently is. This should make it easier to make both large and small planes in Aeronautics since you wont need as much wing area to generate lift. This is the first mod I have ever…
