Do you want a way to your players to Fly, but you don't want to be much "overpowered"? Then you found your solution!
PowerJetpack transforms any chestplate (Default: Chainmail Chestplate) in a Jetpack! Simply equip it, press SHIFT and fly! To be not too much "overpowered", it is possible to configure to have a "fuel" (Default: Coal) that the player need to use to continue flying!

The configuration is in portuguese, but you can change...
