You can make mono and bi plane gliding models with this instructable!
Next up, the paper jet-engine!, also the bi-prop pontune plane(looks mega-cool
Should I post them?
Step 1: Supplies
General supplies for this project.
I am going to instruct you in the creation of mono and bi planes together.
Step 2: Make the Fusalage for the Planes
First, observe the photo, the top card displays the monoplane, the bottom the biplane.
Cut on the solid lines, and the dotted lines. Discard noted pieces.
Step 3: Fabricate the Wings
On the monoplane, fold the wing pieces so they are at a 90 deg angle to their previous location.
There should be a triangular point, which should be folded down.
Open the wings, and flip the plane so you cant see the triangles.
Fold the front of the wings back a little, so it looks like th image. Fold the little piece of the triangles down now. Tape.
For the biplane, fold a fresh card hotdog style (longways) and then fold it hamburger style (shortways).
Your fresh card should now be divided into four quadrants with creases.
Cut the card on the line, and discard the smaller piece.
Fold the tip in the center down and crease.
Step 4: Completing the Monoplane
View the accessory card, and cut out the pieces.
tape the tail on, then the cockpit. Next, tape the wings together at the front. and add paperclips. The next series of images will show you the construction of the prop.
Step 5: Building the Prop
use the bearing and prop pieces from the two planes, as well as two paperclips to make the props.
Just follow the directions on the images.
Step 6: Finish the Biplane
Get the fuselage and wings, and a fresh card.
Fold the card in half, and draw the accessories on. cut them out, and proceed to attach them. add paperclips for weight, and add the prop. Congrats! Nice plane!
Step 7: Making Them Fly.
You need to bend the front tips of the tail wings down at a 45 deg angle, this makes the rear of the plane wan to fly down, and if you throw in the lift from the front wings, the plane will stay airborne.
This would be equivalent to turning the ailerons (control surfaces on the rear wings) up, to adjust the angle of attack on the front wings. Without this adjustment to the plane, it would make a tight loop downwards, and hit the ground. Fiddle around with the tail wings and tail until it flies the way you want it to. If the plane isn't going fast enough to fly, increase the angle of attack on the prop, to allow more air past with less rotations. You want to increase the length of v0 on the diagram (allows more air past) eg: twist it more
