The Uranus Arc III is my own modification of the Uranus Arc II by Nicolas Beaudiez. Although the II is a great flier, it’s not easy to make one that flies well. All I did was add fins to it and now it’s easier than ever to make it fly.
Step 1: Start with a regular piece of rectangle paper that’s 8.5 x 11.0 inches (215.9 x 279.4 mm).
Step 2: Fold the paper in half lengthwise.
Step 3: Unfold.
Step 4: Fold the top two corners to the center as shown.
Step 5: Fold the left and right diagonal edges to the center.
Step 6: Fold the top point to the center of the bottom edge.
Step 7: Turn the paper over.
Step 8: Fold the top two corners down so that the edge of the flaps are parallel to the bottom edge.
Step 9: While folding the top part down, lift up the flap in the back.
Step 10: Turn the paper over.
Step 11: Fold the left half to the right.
Step 12: Fold the wing as shown. Make sure the bottom edge of the wing lines up with the bottom edge of the base.
Step 13: Turn the paper over.
Step 14: Fold this wing as well. Make sure it lines up with the first wing.
Step 15: Open up the wings.
Step 16: Turn the paper over and fold in the fins of the wings. Begin the fold at the top corners of the wings. Make sure the bottom edge of the fins line up with the bottom edge of the wings.
Step 17: Unfold the fins and make it stand straight up. Make the wings tilt up at a slight angle like this. This will help the plane balance in the air.
Step 18: Hole anywhere near the middle of the plane’s base and throw it at an upward angle or straight ahead. Now go to sleep and when you wake up, it will return to you from behind after circling the earth. Kidding. It flies far, but not that far. It will probably only fly halfway around the earth instead.
