## Introduction: Smoothliner IV

How to make this paper glider.

I have made several paper planes and then figured out that this was my best one, so I decided to write up an instructable about it, and how to make it!
This is my 4th model and is quite a lot better than my other 3 models! The more models you make the better they come out!

History of my gliders...

1st- Sort of a fail because its weight on both sides was not equal, somehow...
2nd- Weight and everything okay, but not streamlined enough...
3rd- Not much of a difference, just a little tidier...
4th- Very streamlined and goes really far!

“This instructable was an entry in Paper Airplane Contest 6 (https://www.instructables.com/community/Paper-Airplane-Contest-6/)”

## Step 1: Materials Required

All you need for his make is :

A4 Piece of paper
A Ruler for precise folding

## Step 2: Step 1

Fold the paper in half and then unfold it to make a crease...

If you don't understand anything in this step just watch the video HERE.

## Step 3: Step 2

Fold the top corners inwards to meet to make a triangle as shown in the second picture, and the fold the whole thing downward so that the top touches the bottom of the page as shown in picture 1.

If you don't understand anything in this step just watch the video HERE.

## Step 4: Step 3

Then fold the triangle back upwards( Now its touching the bottom of the page) so that it pops up as shown in the picture 2 and then flip the whole thing so that it looks like the picture 2 and then open the right side flap as shown in the picture 2.

Then pull A down( A is shown in the picture 2) so that A come and touches the center line.

Now press B to the ground so that B overlaps A as shown in the picture with some gap lets call it C inbetween.

Now repeat this on both sides and you are done with this step!

Now on the first picture I tagged an Z and an X keep those in mind for the next step!.

If you don't understand anything in this step just watch the video HERE.

## Step 5: Step 4

Pull Z and X to the top so that they make something as shown in the picture 2, then unfold...
And then pull Z and X the opposite way to form the opposite of what you formed as shown in picture 3.

Now pull up Z so that it sticks up as shown in picture 4 and then fold it upwards so that it becomes like picture 5.

Then stick them both up, and then press them down on the crease lines straight down not up or down like we did before and you will see that they interlock themselves, as shown in picture 1.

If you don't understand anything in this step just watch the video HERE.

## Step 6: Step 5

Now fold the whole airplane in half and then fold N and M outwards ( M and N are tagged in the pictures) so that your airplane looks like picture 2.

Then fold the outermost edges of N and M upwards to make them Q and W as shown in picture 3

If you don't understand anything in this step just watch the video HERE.

## Step 7: How to Fly It!

First you will need to just throw it, and check if it is going smoothly without swirling....
if it is swirling then you need to observe which direction it is swirling...
If it swirls left then you need to increase the M piece at the edge to make it a little more than 90 degrees, and if it still doesn't work then you need to increase the size of the M.

And if its swirling to the right then you need to do the same but to the right side...

## Step 8: How-To Video

Here is the video on how to make it if you did not understand any of the steps!
ENJOY!

I used to make similar paper planes when I was a kid, I guess we grow up too quickly and forget the simple pleasures in life, nice plane!
