Exotic Paper Airplane (the Ketch)

Name: The Ketch | Difficulty: Medium | Last Updated: October 25, 2016

Synopsis: This exotic paper plane takes a unique step away from the traditional pointy nosed paper airplane in its' box like but voracious, jet inspired air intake. The plane will end up being smaller than you probably expect but it really does fly well if folded carefully.

INSTRUCTIONS (Flying tips at the end)


This paper airplane works best with light to medium weight paper. Start with a letter size sheet.

1. Fold the paper exactly in half along its long edge. Unfold after the crease has been made.

2. Fold the upper left and right points down so they hit the horizontal center line crease at the outside edges of the paper. When folded correctly, the top edge should line up with the horizontal center line crease.

3. Fold the lower left and right points up so they hit the horizontal center line crease at the outside edges of the paper. When folded correctly, the bottom edge should line up with the horizontal center line crease.

4. Unfold the two flaps just created so the paper is completely opened up and flat on the working surface. Note that the center crease is not shown here but should appear on your paper.


5. Rotate the paper around so the creases are vertical. Fold the top edge down so it misses the bottom edge by about two finger widths.

6. Flip the paper over so the creased edge is at the top. The paper should open up from the bottom.

7. Make a crease to fold the lower left and right points up. The crease line should be about three finger widths below the paper’s top edge. In fact, the crease line should form squares with the vertical crease lines at each edge.



8. Rotate the paper around so the flap just folded up is at the bottom.

9. Fold the upper right corner of the top-most flap over so it hits the right vertical crease. When folded correctly, the top edge of the new flap should line up with the right vertical crease. Unfold after the crease has been made.

10. Fold the upper left corner of the top-most flap over so it hits the left vertical crease. When folded correctly, the top edge of the new flap should line up with the left vertical crease. unfold after the crease has been made.



11. Pop the lower right corner of the paper up and bring it in towards the middle. The flap should hinge about the existing creases. The upper right point of the top-most flap should be brought up and in towards the middle. Press the whole fold flat.

12. Pop the lower left corner of the paper up and bring it in towards the middle. The flap should hinge about the existing crease. The upper left point of the top-most flap should be brought up and in towards the middle. Press the whole fold flat.

13. Fold the inside right flap over about the existing creases. Leave the small triangular flap on the right edge of the paper in place during the fold.

14. Fold the inside left flap over about the existing creases. Leave the small triangular flap on the left edge of the paper in place during the fold. Hit play forward to finish the fold.


15. Flip the paper over so the flaps just folded are at the bottom.

16. Make a crease to fold the upper left and right points down so they hit the outside edges of the paper. Make the crease so the width of the new flap is about one finger width.

17. Fold the flap at the top edge of the paper exactly in half. When folded correctly, the top edge of the paper should line up with the bottom edge of the existing flap.




18. Rotate the paper around so the two narrow rectangular flaps are at the right.

19. Fold the upper left and right points down so they hit the edges of the paper at the bottom horizontal crease. When folded correctly, the top edge of the paper should line up with the bottom horizontal crease.

20. Unfold the flap just made. Fold the lower left and right points up so they hit the edges of the paper at the top horizontal crease. When folded correctly, the bottom edge of the paper should line up with the top horizontal crease.

21. Unfold the flap just made.


21b. Rotate the paper around so the narrow rectangular flaps are at the top. Flip the paper over so the flaps folded previously are underneath.

22. Make a crease to fold the lower right edge of the paper over so the lower tow points hit the right-most vertical crease. When folded correctly, the lower right edge should line up wit the right-most vertical crease.

23. Fold the flap just created and the flap underneath over about the existing creases. When folded correctly, the right edge of the flap should line up with the nearest inside vertical crease.

24. Make a crease to fold the lower left edge of the paper over so the lower two points hit the left-most vertical crease. When folded correctly, the lower left edge should line up with the left-most vertical crease.

25. Fold the flap just created and the flap underneath over about the existing creases. When folded correctly, the left edge of the flap should line up with the nearest inside vertical crease.


26. Flip the paper over so the longest edge is down and to the left and the flaps just created are underneath.

27. Bring the left and right edges of the paper up and in towards the middle. A rectangular box shape should start to form.

28. Pop the topmost layer of the upper right flap up to open up a pocket. Open up the long narrow rectangular flap underneath the upper left flap.

29. Slide the left flap into the pocket opened up on the right flap. Slide the front edge of the right flap into the opening created by the long narrow flap on the underneath of the left flap. Close the pocket and fold the rectangular flap in and up to lock the box together.

30. Open up the wing flaps on either side of the box adn adjust the wing angles so they are even. Set the dihedral angle on these wing flaps to be flat or slightly up.

31. Open up the flaps on the wing tips so they are vertical. Adjust the angles of the flaps so they are even. Add some up elevator on the back of the wing flaps to keep the nose up during flight. A piece of tape can also be used to help hold the nose together.


THE THROW – Launch this craft level with a long soft throw. Extend the arm to give slow but steady acceleration. With the addition of a paper clip on the nose, a harder throw at more of an up angle will produce a good flight. When trimmed this plane can also be launched straight up. The video shows the wingtips being folded down. I think the plane flies better with the wingtips kept as part of the wing (not folded down). You may need to add a paperclip to the lowerd edge to keep the plane from inverting in flight though. The plane already has plenty of lateral stability and the wingtips are unnecessary and take away from the wings lift area. This plane flies remarkably well in folded carefully.

it rocks!!!!!

it rocks!!!!!

Superb!

When properly folded and throwed it can fly for miles! Best plane ever had. It was hard to fold, but it was worth it :) . Bwaah ha ha, I gonna win the paper aeroplane contest! Thanks for sharing this plane with us!

Real Life plane

This plane looks so real it has proper wings and also the wings can go in the direction down straight or up REALLY CONTROLLABLE!

eeehhhh…..

it was pretty good and it took a lot of work to make but it wouldn’t fly, I might just stink at folding it but it didn’t really work.

it was eeeeeeeeeeeeasy

just follow the instruction or see the video

Guess what?

NO PAPER CLIP NEEDED!!! Just hold the back between your fingers and flick your wrist.

awesome look

Looks cool, flies great, INSTRUCTIONS ARE CONFUSING

cool paper airplane

probably the coolest paper airplane iv’e ever made.

Tape

If you tape the parts on the airplane that always fall apart,it’ll be more stable.

Straight flight

If You Put 1 paper clip on the upper front and 1 paper clip on the lower front and 2 paper clip on the sides

awesome plane

This plane is amazing. Few problems here and there but it is just beautiful. I had to put 2 paper clips on the nose to get a good flight though.

Flying

It flies better if you throw it upside down.

Champion of paper air planes

I beat all of my friends using this one they laugh when they saw this but when they saw it flew about 10 feet i was laughing :DDDD

i found out

i found out that u could hold it with your pincher fingers at the bottom of the rectangle it has in front and swing ur arm then let go it would fly better(i tried this without a paperclip)

Plane sucked

The plane has a good look but flies like crap

Doesn't Suck

I think it’s just because you folded it wrong. The same thing happened to me when I folded it wrong.

Carreful Throw

you have to throw it straight up then it flies well

cool

i think these planze r super cool because they dont have anything in the middle.i call them manta ray planes because of the opening. super easy super fun and super cool

AMAZING!

SO COOL! :D :D :)

so fun and easy

its so easy to make and it glides really cool its so awsome

Awesome!

I loved how awesome this plane turned out to be!

Correct this plane is epic

Correct this plane is epic the dynamics of it is spactacular this plane has several things going for it the top part of the box in the plane will help it stay up the to wings also help out in that area now the sides of the box help it stay strait in the air now adding the staples is a great idea because that will help bring the nose down and keep it flying for longer good idea thanks

Hard…

it was very hard to complete the box and join it together.

Plane is dumb

it wasn't hard for me. but the plane does NOT fly at all….

Epic

It was'nt THAT easy but it was'nt hard, mine flew then fell, 6 staples really helped and it flies amazing and is very tough.

i hate the instructions but

i hate the instructions but after doin it with the video…………….SO SIMPLE!!!

EASY TO MAKE

THIS WAS Vary easy to make but it flys like a champ

Wow

I actually did it

cool alien plane!

this is cool.I like it.Tq.P.S Where did you learn to make it?Please add an answer!

great indoor flyer

It’s a great indoor flyer but it’s pretty unpredictable you might get a good flight or a flop. It’s cool though.

I found that if you add a paper clip

I found that if you add a small paper clip to the top of the nose, fold the sides outward to make the body kind of like a flattened octagon, and fold the wingtips at a 45 degree angle instead of 90 degrees the plane will fly fairly well. It may not work others though, every plane is different.

so cool

it was awesome and easy

good

flies nicely when you tilt the wings up about 45 degrees.

it a good plane

it took me 2 time because i messed up on like the 3rd fold and it effected the last few ones

awesome paper air planes

awesome paper air planes

jon

from Jon I think your airplains are awesome!!!!!!!!!!!!!!!!!!!!!!!!!..

this looks pretty cool

this looks pretty cool i'll try to make one or two or three………….

Strangest paper airplane

This one turned out to be a little smaller that I expected. With a little tweaking it flew pretty well.

It flies but….

This one can be made to fly OK. It is a little heavy with relatively small wing area so it will never fly great. It just looks cool. Try the Paper airplanes for distance link above for great fliers.

wow

if you toss it gently with the paper clip on the bottom it glides 10-15 feet. this is tough but, if you follow the directions CAREFULLY it will work the video helps me understand:)

works????

This looks like it wont work

Ya it works

Ya, But id does! You can throw it hard too.

Hello

It most definitely flies. Did you print out the template. It is a red link below the video at the top of the page. Also I think it flies better if the wing tips are NOT folded down.
