Helflips are pretty hard but to learned them good you stick out your front foot out not to much not to little and the back stays like an Ollie and when you pop your gone wanna flick and slide your front foot but also you got to give it a good pop with it but jump a little higher than board to catch it and if that doesn't work you can just try flicking your board like a helflip and catch it with one foot and when your ready just do all of it in motion
