Hero's Elytra Optimizer
by herobane
Hero's Elytra Optimizer makes a glider stop flying once the elytra is taken off, fixing a long standing bug in how the game handles elytra flight.
What it does
Before this fix, removing an elytra from the chest slot could leave a player still gliding through the air. The mod corrects that behavior so flight ends as soon as the elytra is no longer worn. It is an optimization with a single purpose and adds no new items, blocks or menus.
The mod is installed by placing the file in the Minecraft mods folder, and it needs Fabric API alongside it. Only the player's game needs it, and servers run without it. Files cover 13 release versions, 1.20 – 1.21.11, and the code is open source under the MIT License.
Key features
Stops flight after removal
Taking off the elytra ends gliding at once, rather than letting the player keep flying without wearing one.
Single-purpose fix
The change targets only the elytra flight state and leaves the rest of the glider behavior untouched.
Glide state check
Each tick the mod checks whether an elytra is still worn, and cancels gliding when it is not.
Flight cleanup on removal
Once the chest slot is empty, the player's flying state is cleared so movement returns to normal walking or falling.

Use cases
Single-player survival
A player who swaps elytras or takes one off mid-flight gets consistent movement without restarting the world.
Modded flight items
Players using other flight tools should check compatibility, since the fix stops gliding whenever no elytra is worn.
Who it’s for: Players on Fabric who fly with elytras and want flight to end when the elytra is removed. It suits single-player worlds and clients joining servers that allow client mods.
