You need to start your slide as you normally would but with a pendy you will need to swing your front hand as far back as you can reach....then just allow the board to follow. ...when you want to stop the pendy. Bring your puck down front hand in towards the front truck/ hanger to regain stability on the board. ..

Also, to perform a complete coleman, you will need more speed, otherwise it will stop in haflway when your board turns 180

First you ride into the slide. You can do this by riding bends. Than you just need to put both your hands on the floor. After that you need to kick with your back foot.
