To tailstall, roll up the transition switch with enough speed to get the tail onto the coping. When you near the coping, start to switch nosemanual into the stall and lean into it. Once in position, drop in to dismount.
This is a really good trick for beginners to learn because it is very easy to learn, I did it the first time with just a few tries, and also it looks good(for beginners). Just make sure you don't pop or you're gonne miss the coping. :P
