EarthSmash Flight not working

[namakius]

I am trying to enable flight with Earth Smash.

However when you sneak and right click to board the boulder it just stands still. I am not sure if my config is messed up, or I need to add another property.

here is my config (ignore the mega large durations I was playing around to see if it would work).
