Just Jetpacks is a mod that allows us to create and use a total of seven jetpack variants with which we can fly around the world in survival mode. We need to place these jetpacks where we would place the breastplate of our armor. In addition to flying, they offer us a certain resistance to attacks, since it is necessary to remove the breastplate to use a jetpack.

To use the jetpack, click on the “Space” key to go up and release it to go down. In addition, some of these jetpacks, the most powerful, have a mode that allows us to move in a straight line at high speed. To activate this option we must press the “H” key with the jetpack on our back.
