The plane that we will make in this instructable is very easy to make, you just need to be careful with binding the paper, videlicet, you have to be correct.
So, lets go :)
you should get something like that, and I marked top of the rocket to be more clearly visible in further steps which side is which.
You should get something like that, I prefer using some sellotape to prevent plane from spreading sideward because paper is folded many times and there is plenty of tension in it.
Use rear side of plane to make flaps, in many cases plane will dive or go up too much, you can control that with angle of flaps, it may took some time to learn how to do it right.
When you're throwing it, put the fingers like on picture, that way it will go faster because you'll be using your finger for catapulting the plane. You can also put something through holder (from last to the front side), like stick for barbecue or something like that, that way you'll get you plane more stronger and impact-proof.
