The new "Elytra" can be easily duplicated multiple times.

The new "Elytra" can be easily duplicated. This can be done by while having it in your non-dominant hand, right clicking with an empty hand. This will then create a new Elytra in your armor slot. It can be repeated as many times as the player would wish for.

NOTE: I am not sure what other versions of minecraft this work on, although I am entirely sure that it works on the given version.
