Using brass you are able to upgrade your copper backtank to a jetpack,
using the pressurized air inside to propel yourself through the air.
Inspired by Simply Jetpacks,
this jetpack also has a hover mode.
Like the copper backtank, the jetpack does also go in the chest slot,
feeds air to items like the extendo-grip and can be enchanted with Capacity.
Just like the backtank it is charged by placing it down and supplying it with rotational force.

When underwater while sprint-swimming, the jetpack boosts your swimming speed.
Additionally, the hover-mode prevents you from floating downwards.

If a mod similar to Elytra Slot,
which enables equipping an elytra in addition to a chestplate,
the jetpack will instead give you firework-like boost while the player is pressing the UP-key.
