You need to know how to spin a Kickflip and a half and land on it. Or at least have your Kickflip down really, really, really GOOD!
This trick is best to do of some kicker or I like to do it out of a bowl. Anyway first you need to practice your spinning, so on flat ground you can do 1 and 1/2 of the double Kickflip oh yah you have to be able to land on it too. Anyway come up to your kicker or bowl or whatever and go at a pretty fast speed. Setup as you would for a double Kickflip when you try it on flat ground. Pop it really hard and drag up. When the board starts spinning quickly tuck your legs up as far as you can. The board should be really close to your feet even though you tuck up a lot. Then After you start coming down the board should be done spinning. Catch it and prepare for landing. If its not done by the time you start coming down then you need to spin it faster. If you notice the board is getting higher than you feet you have to some how modify the way you spin the board so it doesn't come up that far.
ive just landed a couple a kickflips noow and wen i tried it after a while of learning them i tried 1 and it did double and i slipped off after being on it for like a second
you dont have to jump high.
