In this instructable article, you will learn how to build and fly your own free-flight glider from foam board. This glider will provide a lot of enjoyment and satisfaction for people. All the required materials are very cheap and this project should not cost you more that $10. Most tools such as tape and scissors and foam sheet will be available in any home.

Be careful around tools such as a hobby knife or the cutter that you are going to use. They can hurt you.

For best results, read each step fully and take your time during the build. DON'T HURRY THIS BUILD

Supplies

Materials Needed:

a. Foam board(5mm and 3mm) if not then use same thickness foam

b. Fevicol SH

c. Hobby knife or cutter

d. Ball Pen

e. Tape

f. Small lead weights (or equivalent- I used some 2" screws)

g. A3 Printer/paper

h. Sandpaper 150 or 180 grit

Step 1: Printing Plans

The PDF plans provided can be printed out on an A3 size paper. if you want than you can print is onto an A4 paper but the size of the final product will be a bit small. If you don't have a A3 printer then get the job done with a printing shop.

Step 2: Cut the Plans

To prepare for cutting, place the plans on your table and tape them down so that they do not move. You can trim some of the excess white area with scissors so that the plans do not overlap the foam. This will give you a better place to tape them down.

cut the fuselage two times on and 5 mm sheet or on 10 mm sheet once then glue the 2 * 5mm fuselage before gluing rub the side of gluing with sandpaper to form great bonds.

cut the wing and elevator on 3 mm foam sheets only once

I recommend you to use a 30cm or a 12 inch metal scale to cut straight lines

Use the hobby knife to make the cuts

Caution: Hobby knives are very sharp! Use carefully.

Step 3: Gluing the Project

The horizontal stabilizer and the wing should be glued to the fuselage Refer to the picture to see what the final product of this step should look like.

sand the lining of the wing and the horizontal stabilizer where it will be gluing to form a good bond

Step 4: Maintaining CG(Centre of Gravity)

Use a 5cm metal screw and plane it with transparent cello tape to balance CG of the plane to make it fly

The CG should be between 20% to 30% from leading edge.

You can check CG with your 2 fingers or by building the CG checking stand.

Step 5: Flying

Use a straight and level toss to start your glider through the air. Be careful not to launch the plane too high or low. Launching nose-high can cause the plane to stall. Launching nose-low can cause a crash. The picture in this step demonstrates a nose-high launch.

If you have a large indoor space, such as a gym, you will see good results and a stable flight.

When flying outdoors, watch for wind as it may cause your glider to go crazy.

it can be also flight by using rubber bands. Attach the rubber bands in the hook type space given in the plans.

HAPPY FLYING!!!
