Fun Polystyrene Glider

This is my first instructable. A fun glider for your children,younger brother or sister .Or just for your self.Its very easy to make and the best part is that you decide the way it looks , how big it is.

As you'll notice the pic is up-side down.You need:1 cardboard box or just cardboard(bigger is better) ,1(or more) any size polystyrene tray ( bigger is better), 1 pencil,1 eraser (not shown),1 ruler, 1 sizers or a knife, some prestick,  and a model aircraft book (optinal)

(If your not using a box skip this step.) Open the box to get( pic 1). Cut out a section (pic 2).You should have (pic 3) .cut the flappy edgers out.Now you have the main pice(pic4)  .  

Start to draw the body, front wings and the rear-wings.A model aircraft book comes in handy here . I'm not telling you my blue print use you creativity. Your drawings must fit onto the polystyrene tray.Tip: be relistice about the wings ,dont have long but thin wings or vice versa, put the front wing high enough so you can hold it.Put the rear wings at a angle just gess it. gess the thickness of thd polystyrene , too small is better than to big.When your done you can start to cut it out.

Sorry i forgot to take a pic for how to trace so i will try to explain how.put the card down on the polystyrene and trace the card out becarefull when tracing and cut out the poly so you have pic 1.

If the wings dont fit use a knife and cut or falttin the poly a bit.Take the prestic put it on the nose of the plan,+ or - to get the balenceing point on the front wing.

There is no garanty that it will work  so dont get too happey just yet,test it if it dosnot fly mess a round with the way you throw the angle that you throw. for fun i would like u to show me your desins .
