Elytra Backtank
by blockmath
Elytra Backtank lets players fly by crafting an elytra backtank from an elytra and a netherite backtank, and it is built for Fabric on 1.21.10.
What it does
The mod addresses a gap the author describes in the Create mod: flight is hard to come by there. A crafted elytra backtank is worn with the elytra, and using its air boost gives extra speed. Flight continues until the backtank's fuel runs out, so the length of a flight depends on how much fuel the tank holds.
A speedometer shows the current speed, which helps a player check whether the flight has reached the ignition speed needed to fire the boost. The mod is specific to the elytra backtank, so it covers one flight item instead of adding a full set of vehicles or machines. It is written for Fabric and needs the Fabric loader to run.
The author's files target 1.21.10 alone, so there is no older or newer build to choose from. The mod runs on client and server, which means the server and every player need it. It is released under the MIT License, but it is not open source.
Key features
Elytra backtank recipe
The elytra backtank is crafted from an elytra and a netherite backtank, making it a gear upgrade.
Air boost
Using the backtank's air boost gives a burst of speed while the elytra is in flight.
Fuel-limited flight
Flight lasts until the backtank runs out of fuel, so the tank sets the length of each trip.
Speedometer
A speedometer shows the current speed, so players can see when the ignition speed is reached.

Use cases
Long-distance travel
Players who cross large maps can fly between areas, with the backtank's fuel setting the range of each trip.
Create-based flight
The mod suits players who want flight added to a Create-focused world, where the author says flight is otherwise rare.
Who it’s for: Players on Fabric who want a flight option for a Create-based world on 1.21.10. Because the mod must run on the server as well, server owners need to install it alongside the players who join.
How it compares
Create Jetpack runs on Fabric, Forge and NeoForge for 1.18.2 – 1.21.1, uses a custom license and is not open source, and runs on client and server. Create: Curios Jetpack & Backtank covers 1.19.2 – 1.21.1 on Fabric, Forge, NeoForge and Quilt, is under All rights reserved, and also runs on client and server. Elytra Backtank differs in its single-version target of 1.21.10 and its focus on the elytra.
