This is version 1 of the craft. At the time of writing there are 2 versions.
This vehicle can travel upwards of 5m on a smooth surface(like vinyl), and once moving can transition onto slightly rougher ones (like carpet).
Step 1: Materials and Requirements
1) Paper, A4
The requirements are a little harder:
1) Smooth floor (eg vinyl, cork etc) to "fly" it on
Step 2: Folding #1
Then unfold it, until it's flat again.
Step 3: Folding #2
Crease these hard. I didn't here, so you can see what's going on, but it is better if you do.
Step 4: Folding #3
Unfold them so they are at ~30 degrees, as in the picture.
Step 5: Folding #4
Step 6: Flying
To fly, put your fingers near the center, push down and give it a shove along a smooth floor.
You'll hear it scrape along for about a meter, and then the noise will vanish as it lifts 1 or 2 mm. It can travel like this for quite a distance. I have got it about 5m, but it will go further if it doesn't hit a wall (mine was indoors in a room 5m long).
Getting it flying is a little hard, and trimming may be necessary.
If the front flips up, then make the front upper flaps more vertical, or push is slower.
If it doesn't rise, then lower the angle of the front flaps or push it faster.
Once it is going it can go onto carpet (if there isn't too bigger bump), or over scissors. If it goes off a step though the front will flip up, nothing you can do about that, it isn't designed to fly, only hover.
Step 7: Take It Further
This one works OK, but I'm sure it can be done better.
Here are another few things I tried:
The RC version is speedy, and can go over concrete at ~20kph (faster than I can sprint, vid)
The other paper one is for my next ible......
