Right Location
Slope gliders require a strong lift of wind created by large hillsides or cliffs which means that you might have to do some hiking to find the right spot. People who live near the ocean should have access to cliffs with parking lots for a landing spot. It's even possible to use a high building as your "wind wall," but make sure there's plenty of free air space around it. It's also a good idea to go with a more experienced flier your first time out.
Inspect Your Equipment
Before you throw your plane check that the center of gravity is not behind where it should be, if it is, the plane could be very hard to control. It's always a good idea to bring extra lead weights with you to make adjustments during your session. Call out the frequency of your radio before you activate your remote control as a courtesy to any other fliers in the area. If you're a novice flier, it's best to use a foam trainer plane.
Launching Your Plane
Throwing your plane in to the wind instead of with it may seem strange but you'll get a better lift if you do. Face the edge of slope and hold your plane level to the horizon and gently throw it in to the wind. Your goal is to get the plane to make small lifting motions when it hits the lift, so don't expect a long smooth take off. Once your plane has hit its wind, bring your hand to the remote control.
Make Adjustments
Making adjustments to the left and right rudder using your remote control will keep the plane on a straight path. The main thing is to keep your adjustments minor. When flying parallel to the hill always remember to turn away from the hill if you want to bring it back, this will give you more lift. In slope gliding, speed comes by giving up altitude, so you can dive below the level of the hill and still have enough speed to catch enough wind to land the plane.
