Air to fakies are actually a little harder than you might initially think, especially if you’re aiming to go big. Try to approach the lip a little straighter than you would for say, a frontside air, but don’t go so straight that you don’t travel down the pipe at all. Drifting slightly down the pipe is ok and will help you with your line going into the next wall.
Once you start coming back down into the pipe, try to kind of look down past your tail and try and figure out when you need to extend your legs again to make contact with the pipe wall.
As with all tricks it makes sense to start small and work your way up but once mastered, the air to fakie is a stylish little number. Tailgrab and indy nosebone work particularly well.
