but, with the ratios I will give you, you can make whatever size glider you like (within an acceptable hand-throwing range of size).
If you have any questions, about the ratios, or the building of the plane featured here, or your own, (or whatever else you can think of, as long as it has to do with hand gliders) feel free to leave them in the comments and I'll get to them as soon as I can.
For this instructable you will need the following items and materials: (look at photo 2) You will also need a protractor for step 6.
If you just want to make the plane: Just look at the pictures and all explanations in BOLD font in the following steps. If you want to build a plane of your own size , follow all explanations in regular font and some of the pictures (as directed) in the following steps.
I chose cardboard to build this plane because it is cheap and readily available, and i had plenty around. However, if you want to make this plane, but you don't have enough cardboard (you need a piece with a total area of about 375 inches squared, with the minimum dimensions of 25x15, so you have enough room), if you have enough styrofoam of the same thickness, use that.
I strongly recommend that you use a sharp knife, such as an exacto, to cut out all parts of this plane or any other you may build for the following reasons:
- scissors can be bulky and use leverage to cut, which may cause a risk of bending the cardboard, resulting in a floppy, almost useless wing or fuselage, that fixing will only add weight which is the last thing you want when building these hand gliders.
- knives tend to be sharper than scissors and their thin blades can cut clean edges, are easier to handle than scissors, and are more accurate, which makes all the difference in factors of flight such as drag, wing area, and weight.
For the right cutting technique, refer to photo 3.
Cut the first two layers of the cardboard, then bend open the cut and slice through the last layer. As I said before, be very careful when cutting, you don't want to bend the cardboard, this weakens it immensely, and you end up with a floppy piece of junk.
For the two important terms that you will need to know when building this glider or your own, refer to photos 4 and 5.
All dimensions I give are measured in inches.
