This datapack allows you to fly with elytra using less fireworks than normal. Simply jump off a cliff, activate your elytra, and you are OFF. Just look in a direction to go that way, and the datapack will give you an extra little boost in that direction. Note that if you take off from the ground, or look straight up, you will need to use a firework rocket to get yourself going. But all in all, this is a cool little feature to have in your survival world and will save down on fireworks. Let me know what you think of it in the comments. I rated it compatible with 1.16 only because idk what has changed in the command world in past updates. The only problem is it tends to lag a bit. This is unfixable and is regardless of how good your pc is
