Jetpack

The Jetpack allows the user to fly continuously by holding the jump key until all fuel in the Jetpack is exhausted. The Jetpack is also equiped with a Hover Mode, which is activated by pressing the M button (while you are also holding the space bar). The Hover Mode will cause the player to slowly descend and consumes much less fuel than the Fly Mode.

When created the jetpack is empty and can be completely refueled by 18 Biofuel Cells or 6 Coalfuel Cells in a Canning Machine.

PROTIP: If you're just starting out, this is not the best jetpack to use. Use the Electric Jetpack which can be refueled easier.

Fall Damage Problems/Solutions
As of Tekkit version 3.1.2, all fall damage can be stopped by enabling hover mode or descending to the ground slowly, therefore eliminating the need for fall damage solutions.
