Hi, Today I'll teach you make
a real science paper airplane
with AIRFOIL.
Airfoil can lift a wing up.
I will explain about an airfoil later.
We need some tools as follows.
Adhesive Tape.
Scissor.
Ruler and Pencil.
We use a standard A4 paper.
Turn to horizontal and fold half.
I usually equalize at corners first.
Then press a folding line just
a few cm. from border.
Do it on both side.
Use both hand and press soft & slow.
Then hard press from center to outside
Release and turn to vertical.
Mark from top for 7 cm.
Then fold.
Equalize both sides.
Press a folding line.
Bring both corner to center.
Make an equal horizontal line first.
Then use an adhesive tape.
3 - 5 cm. long and stick to center.
Turn to horizontal and fold half.
Equalize both corners first.
Both corner.
Mark a point from bottom for 2 cm.
Fold along a body line.
Do another side.
Equalize all corner.
Press.
Mark from top left for 1 cm.
Then fold along a body line.
fold a wing to a center of body.
Do another side.
Start from corner first.
Sometime need to use a folding knife
for better results.
Release both wing to begin step.
Do it on both side.
You will see some folding mark
This mark is 1 cm.
Make another mark for 1.5 cm.
Then use a ruler to mke a line from
1.5 cm. point to wing corner.
Use your scissor to cut this line.
Make sure to release all wing before
cut this line.
Beware sometime you may forget to
release a lower wing.
Slow cut.
Make a mark from head for 11 cm.
And mark for 2 cm. from tail.
Another 2 cm.
Line from latest 2 cm. to top and
line from 2 cm. point form tail
along a body line.
You will have a corner.
Point it.
Line from a point to 2 cm. mark
another line from a point to 11cm.
a bit difficult but worth.
Cut both line.
Fold a wing for 2 step.
Another side.
I recommend to use a folding knife
for better results.

Next, we will bond an airplane head.
Use adhesive tape about 5 - 7 cm.
then stick and round a head.
Do not stick over a wing.
Just here.
We may have an over part.
Cut it.
Bond a body. Use 3 - 5 cm. long tape.
Easily stick by fold a plane first.
Stick in half.
Then cover along a body line.
Bing a vertical stabilizer UP.
Make an Airfoil.
We have 2 layers inside a wing.
Roll a second layer NOT press.
Just ROLL
If you do correct, it will have a pocket.
Like this.
Finally, make a wing to V shape.
This plane can set as adjustment.
But it will not fly so easy.
Cut from corner for 1 cm.
Both side.
NOTE: If you feel hard to fly.
Do not cut it when remake.
Cut at a folding Mark for 1 cm.
Cut at a top of tail for 1 cm.
DONE.
If you like to fly like climbing line.
Set your elevator up both side.
But lower elevator will drive down.
Better to set to center.
Here is a rudder.
Rudder will use for turn your plane
to left or right.
If you want to go right, set rudder
to opposite direction.
then I will explain about an AIRFOIL
Airfoil can make a lift power.
When you throw a plane like this.
A head lift up by throwing power.
A plane will have a high pressure
under its wing but
lower pressure over a wing.
Especially a pocket area.
It will lift you airplane.
This is aerodynamic design that
use in a real airplane.
Try it. You will understand.
