Jetpacks

Jetpacks are a category of armor attachments/chestplates added by Nuclear Tech Mod.

Descriptions
Jetpacks provide the user with limited flight capabilities.

they can be put into the Chestplate slot of a Chestplate on an Armor Modification Table or used as chestplates of their own.

Most Jetpacks, with an exception of the Boostpack, need to be fueled with Kerosene to work. The Boostpack requires BF Rocket Fuel. Just place the packs or chestplates with them attached into an output slot of a barrel or a tank filled with respective fuel to, well, fuel them.

Jetpack
The Jetpack is the most basic one. It can hold up to 12000mb of Kerosene and consumes 5mb of it a second, therefore being able to boost the player upwards for 40 minutes straight.

Builder's Jetpack
Builder's Jetpack's Hover can allow the player to hover in place, and otherwise provides the player with Creative-like flight. This behaviour can be disabled by pressing the Sneak Button.

The Builder's Jetpack is able to hold up to 12000mb of Kerosene. Hover Mode consumes 2mb of Kerosene a second, Normal(?) mode consumes 5mb a second.

Vectored Jetpacks
Vectored Jetpacks boost the player upwards and in the direction they look in.

Vectored Jetpack
Vectored Jetpack can store up to 16000mb of Kerosene and uses 5mb of it a second.

Boostpack
Boostpack, unlike every other jetpack, uses BF Rocket Fuel. It can store 32000mb of the fuel, uses 20 mb of it a second, and is much faster than the Vectored Jetpack.

Trivia

 * A Jetpack Reserve Fuel Tank can be used to instantly replenish any Kerosene-using jetpack by 1000mb of it.
