Make sure you are fluent with getting the deck around with your back foot and make sure your front foot is already reaching for the deck as it swings back around. my problem was I was flicking with my front foot and then I realized that and then I used my back foot to flick and I couldn't land on it but I practiced and practiced and finally got it.

Go to the tail whip section

Practice the motion and kinda jump to your scooter for beginners. But really get the arm motion good and hard. That’s what helped me. But also be patient. This trick took me 3 months.
