The stance for the royale is where your lead foot is in frontside, and your trailing foot is grinding on the outside edge, and touching the boot. When trying this trick you should put your lead foot in frontside, and your trailing foot kind of like soul, but turned 90* so it's facing like a frontside. Keep your weight on the back foot, and have a crouched stance. Also keep your back foot further out than your shoulder or you will fall, and also remember to lean forward. You should try this stance on the ground -or the rail- before you try the grind.
