Introduction: Airplane Giel Decru
This is an airplane that's not difficult to make and that flies very well.
- 1 time 10 x 100 x 0.5 cm
- 1 time 10 x 100 x 2 cm
- 3 mm stick
- wood glue and second glue
- stretcher of 5 mm thick
Step 1: Body
This is a picture of the body.
You now use the balsa of 5 mm thick.
You can print the picture out and sketch the form on your balsa (this is easy but your airplane will be smaller if you don't print it big enough.
or you take the next sizes :
length : 50 cm
height : 4-10 cm
the hole is made 10 cm of the beginning of the body and in the middle of the height.
You make the oblique beginning 10 cm long and start at a hight of 1 cm. Next you round off the front.
The slit is made 2.5 cm to 1 cm of the bottom and begins at 20 cm of the beginning of the body. The slit has a heigth of 2 mm.
In the middle of the slit you start making the stabilisation wing.
Step 2: The Front Wing
Like before you can print the picture out and sketch the form on your balsa (this is easy but your airplane will be maller if you don't print big enough.) if you did this make sure that you take the same proportion as before.
This piece is made of the 2 mm balsa
if you didn't, follow the next steps :
front : 5 cm
back : 8.5 cm
length 8.5 cm
the cutout is made 4 cm of the front and is just 3 mm so your stick can fit/make tension with your balsa.
Step 3: Stretcher
you cut 4 pieces of 2 cm out of your stretcher.
Now you glue them to the balsa front wing starting at the ends of your balsa.
Step 4: Put Your Front Wings on the Body
you put your stick trough the 3 mm hole.
Now glue your wings to the stick. Make sure that your front wings are not to lax.
They may not move by themselves.
Step 5: Make Your Big Wing
Again you can print the picture out and sketch the form on your balsa (this is easy but your airplane will be maller if you don't print big enough.) if you did this make sure that you take the same proportion as before.
this is made out of 2 mm balsa
If not, follow the next steps :
length : 60 cm
width : 17 cm
at the ends : 11.5 cm
first you take 1 piece of balsa and cut is at 60 cm.
Now you draw a line of the middle of the balsa (at 30 cm) to 4.5 cm from of the back of your balsa. Do it again at the other side.
You now cut of the 2 triangles.
Next you take the other piece of balsa and cut it at 60 cm.
The width is now 10 cm. Cut this so you have a width of 7 cm.
Now you glue the 2 pieces of balsa together. Do this also with the transparrent tape.
Now you can go over whole your wings with the transparrent tape. (Bus this is not necessary)
Step 6: Assembly of Your Aiplane
The front wing is normally already on the body.
You now put your big wing trough the slit. If the slit is to small make it a little bit bigger but make sure your wing is not slack.
You now make your first flights and you change the angle of your first wing till the plane flies well.
Now your tape your wings to the body so your wings are fixed.
You can span the wings and the body with the transparrent tape. This is not necessary but it will make your plane stronger and you will have less wind resistance.
If your plane is not in ballans you can put a little weight at the start of the end.
Enjoy your flight !
