This is a mod which makes it possible to fly forever using the elytra wings. It is really useful in case you want a fast and easy way to explore Minecraft. It might be a bit laggy on low-end devices since it requires new parts of the world to load faster. However, I didn’t have any problems and I did the test on a fairly old tablet.
How does it work?
Once you’ve equipped a pair of elytra wings and started to fly then simply look upwards to fly higher. It’s really that simple! There is no longer any limit for how long you can fly.
Here’s a video which does a better way to describe it.
