Introduction: How to Make the UltraDelta Paper Airplane

Very fast, long range and stealthy, the UltraDelta is likely my most advanced flying wing paper airplane to date. This airplane was designed to replace the Super OmniDelta and appease viewer's wishes for new delta wing paper airplane too. I am quite proud of this paper airplane, because it is not a development of any existing model and its characteristics are so excellent. I am sure it will please others just as much.

TAA USAF Designation: F250-1

Step 1: Materials

Required:
1 Piece of 8.5 by 11 inch Paper
Tape
Ruler
Pencil
Scissors

Step 2: Width and Corner Folding

Take your piece of paper and fold it in half width-wide. Then fold each corner down as shown.

Step 3: Airfoil and Counterweight Folding

Fold the tip of your airplane to the rear and make a crease. Then pull the leading edges of the paper towards the center crease and make a crease. Once you've done this on both sides, unfold the paper. Then fold the swept edges in towards these creases. Fold the rhombus in the center forward as shown. Then fold the wing leading edge sections down over the triangle.

Step 4: Making the Fins

Fold your airplane up in two along the center crease. Measure and mark 0.5 inches in from the trailing edge along the center crease. Then measure and mark 0.75 inches outwards from the center crease along the trailing edge. Then measure 0.75 inwards from this mark and make a line this long. Connect this line to the mark you made along the center crease. Cut along this diagonal line.

Step 5: Taping and Fin Folding

Unfold the airplane and cut along the center crease to the half inch mark you made earlier. Then tape along the airfoil sections as directed. Flip the airplane over and tape where designated. Then fold your fins upwards, parallel with the center crease. Pull them away from the center crease and align their trailing edges with that of the wing. Then crease their bottoms.

Step 6: Flight

The UltraDelta is a very fast flying wing paper airplane that can fly very long ranges. Launch technique counts, but is fairly simple. Hold the UltraDelta between its fins and toss at moderate speed. You may need to pinch the airfoil sections to make them thicker from time to time, but do so equally or as needed. Additional surfaces applicable include air brakes, decelerons, elevators, ailerons, elevons, flaps, and rudders. Enjoy!

Nice glider, but pardon, I don't understand well the launch technique (I don't speak English, maybe that is the problem).

You say "Hold the UltraDelta between its fins..." but the surface between fins is an horizontal plane. I always threw paper airplanes taking them by its vertical part. Should I bend it, or should I change the position of my arm?

Thanks in advance.

This picture of the similar OmniDelta should convey the message. This is how the UltraDelta should be held and launched.

OK, thanks and happy Chistmas!

Why did you say that? Both are correct and proper.

author

Thanks Robot, that reassures me.

Thanks and pardon, I don't speak English.

Can you explain me wy not to say happy Chistmas?

i know how

put 3 fingers up the paper airplane and two from the botom and trow it

i made it right

i have 12 years old coooooooooooooooooool

I just want to ask I have not taped the body I just stapled is it fine?

author

I am not sure; the only configuration I tested was the one listed in the instructions.

Are you a talking dog mr

but the throwing process is not working can u suggest any other methods

author

To fly properly, the aircraft cannot be thrown. Instead, you hold it with two fingers on the upper surface and one on the lower surface of the wing between the fins. Once you have done this, advance the UltraDelta through the air at a moderate pace and release it.

The picture below is of a comparable paper airplane that uses the same technique.

Can I have permission to make a tutorial on youtube? I will give you credit.

author

You have my permission to make a tutorial of the UltraDelta on YouTube; please attribute its design to me and add a link to this instructable in the video's description.

Please send me a link to the video too! :)

I followed the guide and launched it the correct way but it keeps turning to its side and failing what should I do

author

Try pinching the airfoil on both sides again equally. If this does not remedy to the banking issue, true making a small elevon on the wing that is dropping and experiment with trim.

I made this and it is awesome but didnt have enough room to fly it so it kept messing up the fins so i built a stabilizer on the fins to hold them in place and ensure strait flight

its about 2 inches by .5 inches

Is the stabilizer made out of another piece of paper, or the same as the rest of the airplane?

author

i added a few more folds to make the plane more dart-like due to my lack of space and the results are rather neat-looking and easier to launch
i folded up the wing tips for stability and folded in the wigs to an interior angle of 30
degrees as opposed to the previous 90
and i am using the tape stabilizer which creates a neat looking circle above the plane

It'd be wonderful if you'd make an instructable on the new variant! :)

author

It is another piece of paper in the photo but i later made one out of two pieces of tape
