Find a room or area where there are few drafts. Any wind other than what you generate with the controllable slope will make the glider fly off course. For instructions on how to fly the paper airplane walkalong glider, see the step 4: Powering and Controlling the Surfer Paper Airplane from the paper airplane walkalong glider Instructable. Launch the glider from as high as possible (as high as you can reach while standing up) so the glider settles into stable flight before it descends to the level of the controllable slope. Below, a piece of 96cmX75cm corrugated cardboard serves as the controllable slope.Next try keep the glider from going down and make it fly for a longer time and distance. Secondly, try to steer the glider through a doorway. Ultimately, getting the glider to climb higher will give you time to maneuver better as the glider will lose altitude in turns.
