This is an airplane of my own design which is a variant of the standard paper plane with bottom wings. This is quite easy to make and glides really well.
If you make this please post a comment. If you like this then check out my other Instructables.
Step 1: The Fuselage
This is almost like making a normal plane but with a small twist. first, fold it in the middle as usual. Then here comes the twist. Instead of folding the corners in, about a centimeter from the middle fold, fold the two sides into each other. Then fold them back at the middle line. I would suggest using glue. It should look like in picture 3. Then fold the two large bits down again and make a paper plane the normal way, by folding the corners in, folding them in again, folding it in together, then folding the wings.
Step 2: The Thrower
To make the thrower cut a slit in the center hole, Then cut two slits in the fuselage just below the wings. Fold up some paper into a flat bar about a centimeter in width and then cut a little along the fold. Fold the two tabs you will have created down. The tabs go in the slits you have cut below the wing and the main thrower goes in the slit you cut along the middle fold. I would suggest gluing this. Then cut off the tab but make sure there is enough for you to hold on to. your biplane is done!
Step 3: Throwing the Biplane
Hold on to the thrower and chuck it gently. The longer you hold onto it when throwing the longer it will fly. But make sure the wings are horizontal at all times. I had to put two paperclips onto the nose to get it to fly properly! This is just a fun little plane to let your children fly, (and you can fly it, of course.)
