There is a fascinating trend to the 25:75 placement ratio. Upon measuring and testing my MetaVulcan design, I found that 72% of its wing area* was located behind the center of gravity. Only 28% sat ahead of the CG. (*The area of the canards was counted as wing area.)
I followed all of your videos on how to design a paper airplane and I made one the flies 75 feet with my own throw. Its name is Seaker. Thank you very much for teaching me Khyle!
Sunstreak is an amazing glider that I designed. It was the best(and only)airplane I ever deigned .(for me)it flew ten feet. Do you want the folding sequence?
absolute chad. my friends are folding the elevators too much without knowing what it does and they can't make a good paper airplane which makes them come to me.
Without seeing the plane, I can't answer for sure. But, my first guess would be exactly what this video talks about - that the center of gravity is too far back on your plane. Can you describe how it flies?

Hi Randy. Almost all paper airplanes are symmetrical from right to left, so you already know the CG has to be on the center crease. Then, if you balance the plane on a string and find its tipping point, you have located the CG from front to back. Finding the CG's placement on the third axis is very difficult, and not consequential for most planes, so I didn't worry about it in this test. The front to back placement of the CG is really what determines whether it stalls, dives, or flies well.
@@FoldableFlight I too know that the CG is in the center of the plane but on all aircrafts it's not on the center. Like the boomerang plane of John Collins should also have CG in the center but why John always says that the center of gravity is behind the lift and there's not too much large layers too behind the plane,and one more thing we can't carry string all the time everywhere and we can't even make holes in plane always to check the CG what in this case then how we will find it. And one more doubt if the CG is in the center then how can be it further moved back or forward? and please tell the mathematic formula too for finding CG percentage.
@@randyorton7997 Okay - so you are touching on some important things. John Collins' boomerang plane (and mine, Circuit Racer) function the way they do, not just based on the placement of the CG, but based on the relationship between their centers of gravity and their centers of lift. A plane's center of gravity remains at a single location, while the center of lift changes based on a plane's attitude (angle) and speed. Basically, on most boomerang planes, the CG is behind the center of lift, which encourages the plane to climb. If you throw the plane in a banked attitude, it "climbs" in a circle back to the thrower. You mention that you can't carry string everywhere to identify a plane's CG. That's fine. You don't need to identify the exact placement of a plane's CG in order to make it fly in a certain way. If a plane dives at a given speed, it's CG is in front of it's center of lift. If it climbs at a given speed, the CG is behind the center of lift. If it glides level, the CG and center of lift are at similar points. So you can infer something about the relationship between the CG and center of lift by how the plane flies, rather than worrying about making measurements and mathematically calculating the CGs placement. And if you are trying to locate the plane's CG, there is no need to make holes in the plane. I just balanced it between two strings of fishing line and found the tipping point. The plane balances on the bottom line, while the top line helps you mark the correct point on the plane. I calculated the CG placement in relation to the wing area by using geometry to calculate the area in front of and behind CG. There is no single formula for this. You pretty much just need to know the formulas for rectangles and triangles. The area of a rectangle is length x width. The area of a triangle is 1/2 base x height. Once you calculate how much area is in front of the CG, divide it by the total area of the plane to find the percentage of area in front of the CG. As for how to move the CG backwards, I discuss that to some degree in the video. It's also worth knowing that anything I said can be done to move the CG forward, the opposite can be done to move the CG backwards.
I found the CG (same as center of mass in uniform gravity) and then calculated the area in front of it and the area behind it. I found this to be much more significant than just the distance in front and behind.
hey can you tell me @FoldableFlight if you would be able to make a paper airplane with 4 wings without using 2 sheets of paper because that's what I want to do
Yes. I'm saying 25% of the plane's total area is in front of it's center of gravity, while 75% of its area is behind the center of gravity. As demonstrated with the block at the beginning, 50% of an object's mass is in front of the center of gravity, and 50% of the mass is behind it. This means, on many good paper airplanes, 50% of the mass of the plane is fitting into roughly the front 25% of the area of the plane.
25 percent equals awesome [I DONT THIK SO] I did the test you did it took 25 days to make a crumpled paper [Just kidding] #LOVEFOLDABLEFLIGHT #MOREVIDEOSPLEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!
Thanks for watching! You can find links to the folding tutorials for the planes in the video in the description!
Hi mate
@@williamsrensen8449 Hello!
@@FoldableFlight How many papers do u think u have used in the plane folding community?. I am the guy who asked if y had a Facebook.
@@williamsrensen8449 Do you mean, "How many sheets of paper have I used to fold paper airplanes?"? I don't know... thousands, for sure.
*OH YEAH YEAH*

That's cool to hear. I'd love to compile more data if you were inclined to test more of your planes.
I subbed to u year
0:32 you have a great day
That's the only thing that is a great idea
I followed all of your videos on how to design a paper airplane and I made one the flies 75 feet with my own throw. Its name is Seaker.
Thank you very much for teaching me Khyle!
OMG you made my trashy planes too good it turned from a crasher to a plane that goes vertically up, and gently glides down.Too high for this roof XD
”And then i did a little bit of meEth” 3:07
Lmao😂
Please teach us how to make the plane on the cover
It's called Spectre and it will be in my upcoming book!
@@FoldableFlight Oh!i made the spectre plane from another book.It looks similiar you yours.
wow it taught me so much
Look at the end of his *Awkward laugh
He's looks so depressed lol
0:14
Thanks for the tutorial made a plane named vensten flies really well
I got an A on my test. Wonder if would dramatically improve my planes
Nice kyle
COOL
Hi Ramya you are the best
That 25:75 ratio is very cool!
I was really surprised, because I was trying to test a fairly wide variety of paper airplanes. I didn't expect that kind of consistency!
I am so happy to hear 🎉thank goodness for you guys for your service
My mind is blown up 😮😮
loved the 24 reference
Thanks!
I got it correct at 2:48 yay :D
Kyle,I really did design my own airplane and I call it the flash 777...because i think it is a bit too fast ....... thank you!😄😄😁
Nice!
i am happy to make my first ever design
thanks khyle !!!
Appreciate what you are doing
Thanks!
I love your videos and your ideas
wellllll that is helpful
Sunstreak is an amazing glider that I designed. It was the best(and only)airplane I ever deigned .(for me)it flew ten feet. Do you want the folding sequence?
7:34 "Why is this guy so weird?" haha
Nice.
Thanks!
Is very good
i subed because ur planes are too good
OMG Thanks I love your content and what you do.. greetings from Denmark
Awesome! I'm glad you're enjoying my channel. Greetings from America!
@@FoldableFlight Can we some time get a studio tour?
I watched this video and just made my new paper airplane- Magnus. It flies quite high. It has a high lift.
I've made 1 but it doesn't have a lock hopefully I can learn a lot of locks
Nice
On 0:41 he said "dramatically" Emphasizedly my pad went dark cuz my charge was 5 XD
lol
absolute chad. my friends are folding the elevators too much without knowing what it does and they can't make a good paper airplane which makes them come to me.
Nice content.... good foldable flight.... I had designed one paper airplane but it doesn't fly well bro Whats the reason for this???
Without seeing the plane, I can't answer for sure. But, my first guess would be exactly what this video talks about - that the center of gravity is too far back on your plane. Can you describe how it flies?
@@FoldableFlight my plane that I designed dive itself to ground
But how i share my picture of paper airplane to you?? Through facebook / instagram??? Plzz reply
your funniest vid ever
nice !!
orange will fly the best
Kyle i sant you to post more often pls i cânt wait one week PS. i know it takes a lot of time to design a plane .
The green plane is far worse that the blue plane
4 : 35 i died of laughter
Wow did u get surprised when the green plane stand?
Yeah. Kinda cool, huh?
Of course
I did that a few times
2:27 My vote is green.

Thian Piang where
red the best
number 1
I learn paper aeroplane thanks
red one will fly nicely
How did you find out your paper airplane center of gravity ,
Please answer ?
this is me lol 0:19

i like bikes and paper air panes
The blue plane ✈️ Well fly far
i like the blue airplane
At 2:41 the green plane actually lands
Like for the green airplane because when it fallen it in the ground was vertical
The orange one
I think the red one goes the farest
Made a very long looking suzanne like plane with canards, it’s a glider.
Paper airplanes man
Your junior high days are over!!
That doesn't mean I have to stop enjoying paper airplanes :-)
cool
the green one
I thin the green plane will be the best.
Red We’ll fly the best
Green because it's balanced
Hey Kyle, I was looking through the comments and saw that you were going to make a vid about viewers planes, can I submit Goodson,my plane
Please do! If you can send me pictures or video of how to make the plane at Facebook.com/FoldableFlight, that would be great.
But are you measuring area or distance from the center of mass?
I found the CG (same as center of mass in uniform gravity) and then calculated the area in front of it and the area behind it. I found this to be much more significant than just the distance in front and behind.
@@FoldableFlight thanks for the clarification!
I wasn't sure what you meant in that part.
the red one
Will you make the plane at the thumbnail or is it nearly impossible?😕
The plane from the thumbnail is called Spectre. It will be in my book (coming out later this year)!
@@FoldableFlight thx
Yay sorry I was late youtube is glitching again the glitch is that you can’t open your comment if someone commented on your post
Foldable Flight is spectre hard to make or intermediate?
@@FoldableFlight I folded spectre with the template and then sentry with the template and they look cool. Thanks Kyle!!
Red one
Red
I think that the yellow one flies best
Blue
i made a paper plane i called it xenon it is a hybrid it flies really well
Back when I can't fold good paper airplanes the paper airplane just flies straight to the ground.
Well, this video might tell you the problem with those planes!
Yeah,dude. great vid.
@@p1nstark Thanks!
Orange one
I made lightning hybrid
thje green one
The yellow one will fly better
That was my guess too!
Green 2:35
I guess orange plane will fly best
I think the red one will
Green
hey can you tell me @FoldableFlight if you would be able to make a paper airplane with 4 wings without using 2 sheets of paper because that's what I want to do
Check out X-Fighter or Falcon X on my channel :-)
Red one because it has strong edged wings
green
The orange plane
I guessed the orange plane
I MADE MY OWN PAPER GLIDER 😘😘😘😘😘😘😘😘😘😘😘😘☺☺☺☺☺☺☺☺☺☺☺☺☺
Which is the plane in the thumbnail ?
It's called Spectre. It will be in my book!
I clicked because of the thumbnail
Tru
I designed glider but I don’t know what to call it
is the 25 percent and 75 percent means 25=75 percent of plane? ı cant understand it is a high english can somebody help me!
