Pizza Box Airplane

Picture of Pizza Box Airplane
Don't throw away pizza boxes, make them into airplanes.

What you need:

1+ pizza box/boxes (with as few grease stains as possible)

1 keychain ring (circuler metal thingy)

Scissors (preferably sharp and big)

Tape (duct, scotch, blue, anything)

Ruler (trust me you'll need one)

String (sorry it wasn't here before)

(I beg you to look at the comments)

Step 1: Body

Picture of body
Cut out a piece of cardboard roughly this shape.

From one side to the other it measures about 14"

This is your body,

next is the wings

(don't pay attention to the slits :] )

Step 2: Wings

Picture of Wings
Cut out a piece of cardboard that is roughly shaped like this,

it is about 15" side to side and 3" wide,

if your confused with measurments use your head and look at the picture.

Step 3: Back Tail

Picture of Back Tail
It's like the wings but smaller.

Make it roughly this shape,

It measures about 7" across and 2" high.

Once again, use your head.

Step 4: Weights

Picture of Weights
Cut out shapes that look like this or the shape of the nose.

They should be 1 1/2" wide and the height may vary according to your plane's nose.

Step 5: Slitting

Picture of Slitting
Make slits in your plane as wide as your plane wings.

Look at the picture to see the spacing.

For the slits, you can try altering the angle of them, for more lift, which should in theory keep it up longer.

Step 6: Shoving In

Picture of Shoving In
Shove the wings in.

If you need to use tape to make them stay in thats what it's for.

Step 7: Nose weight

Picture of Nose weight
The weights go on each side of the plane nose.

Attach them by the key chain.

(Sorry it's so blurry look at the intro picture to see it clearer)

Step 8: GETTING IT TO FLY!

Picture of GETTING IT TO FLY!
It should be ready for flight but if it dosen't work,

try pushing the wings up so the don't sag,

or cut a slit right above the big wings as shown.

Hey, this is amazing model. I like it very much - the form is simple, original, construction too. Viva pizza airplane!

Not necessarily, if the angle is too steep the plane will stall, then fall. May be better to have a smooth flight in descent, than a sporadic flight ascending a little then descending a lot.

True!

Wow did you take airplane physics! I'll try it!

This is a great Instructable. Anything that encourages experimentation with flying is a great project. This one gives you new materials every Friday night! As he said, use your brain and do it. This doesn't cost much and nothing is going to break. Just do it. Experiment with slit placement forward and back as well as wing and tail slit angles up and down. You might not need to add weights if everything works out right. You could also tape a vertical tail to the top or bottom at the back. Try different sizes of fuselage, wing, and tail. There is no right or wrong answer. Every plane will have good and bad features. Just do it.

Nice instructable, despite the blur pictures (look http://www.instructables.com/id/How-to-take-clear-pictures-for-Instructables-with-/)

I think the string must be UNDER the wings, because the wings tends to lift.

Besides, the balance of the frontal counterweight is very simple to achieve: put a finger under the average line of each wing, and the fuselage (aircraft body) should remain horizontal.
He might have put the string on top to maintain dihedral angle for roll stability. You still might want a string underneath to keep the dihedral more or less constant. String was not mentioned in the list at the beginning.
