This paper airplane design was fabricated from 100 percent reused materials, from the 8 1/2 X 11 sheet of paper to the 96cm X 75cm corrugated cardboard salvaged from the trash. this is a good way of reusing paper and cardboard before ultimately recycling them.
The surfer paper airplane is designed to fly as a walkalong glider. Paper airplanes are heavier than other walkalong glider designs and fly correspondingly faster. A 96cm X 75cm piece of corrugated cardboard was used as a controllable slope to power (sustain) and control the surfer paper airplane.
The nose assembly is used for many other paper airplane designs which differ from this paper airplane walkalong glider design only in how the fins are folded. The nose assembly is similar to the trapezium paper airplane design
The last fold on each wingtip is what distinguishes this glider from the rest. This fold starts at the front where the first fin fold intersects the leading edge of the wing. Then the edge of the fin is lined up with where the first fin fold instersects the trailing edge of the wing. This fold results in the outboard wingtip having a reduced angle of attack relative to the inboard wing, a design feature called wing washout
The paper airplane walkalong glider is now ready for a flight test. Launch the plane at a slight nose down atittude on a down angled trajectory. If the plane flies straight it is ready for walkalong gliding. To correct a turning tendency, gently pull out the outer fin on the side of the turning tendency. This increases lift by increasing the angle of attack on the wingtip, making the plane tend to turn in the opposite direction. In the following video a paper airplane walkalong glider is turning to the right. The plane is then adjusted, folding in the left fin and pulling out the right fin so the next flight flies straight.
