I know your Elytra is brand new. But I found a little bug after using them for a while.
If you go down a tall ladder with the Elytra on, and look down, you'll fall down in high speed.
It's probably not a big issue. But it would be sad if someone played Hardcore, got the Elytra, and died because of ladders.. (And it's also a bit frustrating 😛)

kinda stinks this was changed. I made my entire world so I could fly up and down my ladders. I've never experienced falling, without clicking the 'jump' button a couple times. Regardless, it use to save me loads of time
