Hi, Suspence1127 here, and this is my new project:

Vanilla flying machine! This is an updated version of xisumavoid's flying machine for 1.6. I have updated this for 1.8, however it is much larger and buggy (New update fixes most of these bugs tho :D ). If anyone would like to try to make this work better, be my guest. Now for the device!

The device is a box schematic that you post in your world. You hold the items given to you in a chest inside the box that lets you fly in survival by using enchanting it /replaceitem on your item, and teleporting you. *Note*Before you can fly, you must enter the box (via lever door) and set it up. There are instructions inside.

Download this map and try it out, or download my redstone world which also has this.

TO INSTAL:
Put this box in your spawnchunks and Enjoy :D
*Note* This seems to sometimes not work as well, depending on where you place it in the world.
