I've been making this plane for years and it can provide lots of entertainment. It's not like an ordninary plane that just goes straight and fast- They're kinda boring, but this plane will loop, spiral, corkscrew, skim the ground and perfom many more stunts.
Step 1: Step One,the Base
For this plane you start with a piece of A4(foolscap)paper and fold a waterbomb base. If you know how to do this, skip this step.
first, crease from the top left or right diagonally down as if to make a sqare, and do the same on the other side, then turn it over and make a horizontal crease where the 2 diagonals meet, now if you turn it over again and press the place where all the creases meet it should pop up slightly, pull this popped up piece down so the top of the diagonal creases meet the bottom, there will now be triangular areas outlined by the creases and you should be able to push these in to the other existing triangle.You are now finished!
Step 2: Step 3,main Folds
You will notice that there are 2 raw edges in the waterbomb base, fold these up to the top point, crease and fold back so they are standing perpendicular to the rest of the paper, then squash fold them so each top point it touching the bottom middle of the base, they will look like 2 sqares,crease them.There is a point on the top of the paper, fold that down into the newly folded space and fold the squares back over it so you cannot see it. make the basic fuselage folds (fold in half, fold down,etc)and fold the wingtips up. your plane is now ready to fly!
PS: I also find that changing the size and weight of the paper changes how it flies. Also try not to make the fuselage too thin vertically, as if you do, the squash folded squares will pop up and act as two big brakes, thus ruining the flight.
Step 3: Step 3,flying
This is by far the easiest step to do.When you have the plane, you will notice that there is a thicker piece on the front of the fuselage, hold the plane at the end of that thick piece and throw as hard as you can at an angle of about 60 degrees and watch it go! is it doesn't work, just tear 2 flaps in the back of the wings and crease them upward.
Also, Experiment with different factors, such as the length and angle of the stabilisers, the depth of the fuselage, the size of the paper, the thickness of the paper, the way you throw it and which way you throw it. All of these changes will hreatly influence the way the plane flies and lands.
