Use sticky notes to make a glider. In the actual test, the glider slid about 18 meters from the 2nd floor in a light wind. When flying on the 6th floor, I was afraid that it would not be able to recover, so I adjusted the tail to one side and let the glider circle and fly. The radius is 15-20M, and the blank time is more than 1 and a half minutes!
Although this sticky note glider has excellent gliding performance, it is difficult to maintain a stable direction. Therefore, children who want to use this note glider as a small note glider must be cautious. If there is a leak, the teacher will make him stand, or he will be chased by a girl. Fight at your own risk...
1 Materials and Tools
Pins are used for fixation and can be replaced with other tools.
2 Wings
Attach two sticky notes together: In the picture, the orange sticky note has the adhesive side up, and the pink sticky note has the adhesive side downward. The orange side of the bonding surface has adhesive, and the pink side has no adhesive.
Add another piece of sticky paper. The part where the blue sticky paper and the pink sticky paper are bonded is adhesive-backed.
Check whether the remaining single-layer sticky notes on both sides have the same length. If they are different, they need to be adjusted.
Align and press the blue and orange sticky notes in the middle of the wing, and then fold them in both directions. There are two advantages to making the wings this way: all the adhesive parts are covered, so the wings will not be stained when landing; the three strips of sticky notes form a four-color gradient, which is more beautiful.
The final step is to fold it along the center line. The illustrations show the folding methods of the upper and lower wings respectively.
3 Fuselage and tail
Fold a piece of note paper along the center line, and let the adhesive surfaces stick together to form the body. Try to avoid distortion, otherwise the subsequent steps will be very troublesome.
Adhere the two sticky notes together (the adhesive side and the adhesive side are completely aligned) to make the tail fin.
Then cut into two parts along the midline.
Fold down the part without adhesive.
Assembling the tail to the fuselage will cause the center of gravity to shift rearward, so weight can be added to the nose.
Use a pin to separate the two sides that are glued together.
Attach them to both sides of the fuselage, then attach them tightly, and the tail will be installed.
The machine head is wrapped with sticky notes as a counterweight.
Finally, cut off the remaining part without adhesive for later use.
Do it again.
The remaining material from the front is used as a counterweight!
First stack the two large pieces together and fold them in half twice.
Then separate the small ones with pins and attach them to both sides.
Finally insert it into the gap in the machine head.
You can also insert it deeper.
4 Final assembly and adjustment
The wing installation is completed, and the glider is made into a lower wing. In fact, it has a sister with an upper wing.

Whether it is the original version or another version, the next process is the most important - debugging! Since the adhesive backing of sticky notes is not very sticky, the main parts of the glider are adjustable...
Let’s talk about the wings first. The wings should be installed with a certain positive angle of attack. Of course, the size is up to everyone.
Lower the single wing.
On the single wing.
The remaining adjustable parts include: the installation angle of the tail wing and the installation position of the counterweight.
In fact, only one tail fin is installed. Two are installed to show its adjustable angle...
The relative position and installation position of the two counterweights are also adjustable.
Basic principles of debugging:
1. The upper monoplane is more suitable for smooth gliding, while the lower monoplane flight may be unstable, but it is more likely to make somersaults, circling and other movements.
2. The center of gravity of the aircraft is generally located one-third of the length of the aircraft, preferably coincident with the position of the wings.
3. If the glider raises its head too much and makes wavy flight or even cannot fly, the counterweight should be moved forward or the tail should have a positive angle of attack.
4. If you feel that the gliders flight path is too close to a parabola, you should move the counterweight back or make the tail have a negative angle of attack.
The monoplane flies pretty well, a perfect parabola. The wings don't fly very well. This should be a manufacturing problem. The wings are not very symmetrical. Lets adjust them slowly by ourselves~~~
