I'm going to show you a glider made of paper. This one is made to not be thrown.. he he...
I would like to excuse myself as I may need some more english vocabulary to explain myself.
You'll understand later why I called it 'unthrown', to explain that you don't have to throw it to make it fly. Let's see now the few steps to build it, then I'll explain you how to make it fly.
Step 1: Making the Base Fold
fold you sheet of paper in the middle following the length
Step 2: Prepare the Front of the Plane
- mark with folding the corner like first pic. Then unfold. It should look like second pic
- then fold over the mark (this new fold should be on the crossing of the first 2 folds). You should get 3rd pic.
Step 3: Make the Front Body Plane
- fold the corners like 2 firsts pics
- fold the front 'point' up to the middle of the back
Step 4: Making the Body
First, return your plane and then inverse the center fold so that previous fold is outside the center fold.
Step 5: Make the Rear Flaps
fold the rear of the plane on about 1 cm
then unfold it
It should look like picture
Step 6: Finish the Body
fold as sooo many other paper planes to make something to catch the plane with you finger
Step 7: Finish the Tail Flaps
Put the plane on "its side" (first pic) and cut with a sharp knif or use scisors (2nd pic). The cut goes on the body, i.e the fold you catch with your finger to throw the plane, at the rear (3rd pic).
Then return the plane, and reverse the back of the body where you just cutted, so that it become over the plane like a vertical flap on real plane (arg... so hard to make myself understandable) see 4th pic
Step 8: Finish
Now it's time to tune it !
First take the body between your fingers and with your other hand lift the wings to make a light "V shape like"
Make sure the tail flaps are not too much folded
Step 9: Make You Plane Flight
This step is exactly what make this plane so special I think.
Contrary to many planes you don't have to throw it.
Just catch it at the rear of the body between your fingers and let the nose facing the floor.
Put your hand at the maximum height as you can
Now you're ready, just release the plane, it should go down, catching speed, then fly normally flat with a beautiful and very interesting flight.
If the plane want to go up too much, try softing the rear flaps fold
If the plane goes directly the nose on the floor, make the rear flaps fold more aggressive.
If the plane turn or if you want to make it turn, you can play with the shape of the rear flap folds only on one of the side. Try left or right and see the effects
If you don't want it to turn try to sharpen the 'attack fold'. Fold it very good using something hard.
