[1.6.4] Simply Jetpacks Mod Download











The main feature of this mod, of course. They are pretty straight forward. You have to wear them in the chestplate slot. Press F while equipped to activate/deactivate a jetpack. Hold the jump button to fly. Press C to toggle hover mode with a jetpack. In hover mode, you descend slower and a jetpack will consume less power. These controls can be changed.
By default, all jetpacks will emit particles when in flight. This can be disabled in the config.
Recipes to ‘upgrade’ jetpacks to the next tiers are available, though this is not really cheaper, just an utility so you don’t have useless jetpacks laying around.

These jetpacks follow the Thermal Expansion tier system: first leadstone, then hardened, then redstone and finally resonant.

Leadstone Jetpack


The most basic jetpack, made mainly of lead. This jetpack holds only 25,000 RF and empties very quickly, but is very cheap. It can’t fly very fast. In total, it will last for about one minute in normal flight mode, and about one and a half minutes in hover mode.

Hardened Jetpack


A slightly better jetpack than leadstone, made of invar. It holds 400,000 RF and lasts a bit longer than the leadstone jetpack. It is also a bit faster. In total, it will last for about four and a half minutes in normal flight mode. About six and a half minutes in hover mode.

Redstone Jetpack


The third tier of jetpack, made of electrum. This one is significantly faster than the last two. With an internal storage of 2,000,000 RF, it will last for in total about eleven minutes in normal flight mode, and sixteen and a half minutes in hover mode. This jetpack will also descend more slowly in hover mode, unless you sneak.

Resonant Jetpack


This is currently the best jetpack in the mod. It’s made of enderium. It’s close to creative flight, but it’s not quite there. When in hover mode, it will descend extremely slowly when you are not sneaking, which could be useful for building. This jetpack holds 10,000,000 RF, so it can take a while to charge. Once full though, it will last for about 21 minutes in total in normal flight mode, and about half an hour in hover mode.

These are just some simple items that are used to craft the jetpacks.

There is also a potato-powered jetpack, however because of its tuberous nature this jetpack is considered to be quite unstable and its usage is discouraged.


This is a small mod that adds Redstone Flux-powered jetpacks to the game. If you don’t know what Redstone Flux, or RF is, it’s a power system that is used by Thermal Expansion, and some other mods as well. This mod is an addon to Thermal Expansion.
