try them on a quarter and whip late on it and you have to know how to whip catch flat it helps a lot and when you feel the deck coming under your feet slam down and when you get that down then start to work on fakeying out of it
learn to whip really fast. then find a kicker or quarter and spin it just like a tailwhip but a little bit faster and don't give up on it and you will eventually get it
just learn the motion find a good ramp and get a bunch of speed and throw it http://www.youtube.com/watch?v=U0A1FI1wHeo&feature=plcp&context=C34d54cdUDOEgsToPDskIl8ZlqwE-7R8l4EJpUfCTX
watch some beginner comp edits to see if you match up and if you think you do then enter, what's the worst that can happen. you make a fool of yourself like you did making this thread. ;)
