[glitch] Flying without wings!

This is a client sided glitch only but it looks pretty cool. Here's how to do it:
1) Fly
2) Press fly off, then just before you hit ground, press Fly (Countering for lag!)
3) On your screen you have no wings :D

Only tested with EP on international server but should work on other servers, took me 5 shots to get it right, think i saw it on youtube :D

Is this working in brazilian PW? is this working for other class?
Anyone knows?

by the way, you must have wings on, it is just for looks, works on all servers just is extreamly hard to pull of if you have lag, once i put my wings on again, i was trying foir 2 hours to do it again with no luck :(
