Kline/Fogleman Airfoil #1 Paper Airplane

Picture of Kline/Fogleman Airfoil #1 Paper Airplane
This paper airplane is my interperation of the Kline/Fogleman Airfoil. ?What's that? you ask. It is an airfoil design that incorporates a "step" into the wing, that seems to make a plane fly smoother and with less chance of stalling. It can be stepped on the top or the bottom of the wing. My design is on the bottom, and is adjustable as well, so you can decide how you want your paper airplane to fly.

A more complete history of the Airfoil can be found on this website,

and if that is not working, I have backed the site up here.

Enough technical talk though, it's time to build great flying paper airplane!

You can adjust the chord of this paper airplane by pulling down on the two vertical folds under the wing. The depth of the chord will greatly effect the way this plane flies, so feel free to experiement at will!

NOTICE! Your link to the template is invalid. Microsoft will not open the file as it claims it is an invalid file source. I would love to make this plane but cannot seem to be able to get ahold of the template.

Just tried it, and my computer opened it just fine. But it is an older file type, so that may be the problem. I just added a PDF for you and it is located on this page just under my website information, above step 1 on this page. Hope this helps! dean :)
Thanks! I really aprreciate your effort to make this possible. Keep up the good work!

I have been looking for this for years. I was in fourth grade and found it in an Omni magazine. I made it and, with a friend, sneeked into the gym between classes to fly it. The magazine boasted it to be the world's longest flying plane. It was the truth because on my first flight it truely circled the gym perimeter three times. We were amazed. It's second flight started out pretty well but became lodged in the rafters and there was no way to recover it. Beforehand I had rallied the teacher for a paper plane contest and thought I would steal the show. Without time and know how to make another that day, I made an ordinary plane and was beat out by some kid who loaded his down with so many paper clips he might as well had thrown a chunk of hematite. Thanks for this post. I haven't read the details, but I do recall the Omni magizine plane template was a heavier paper - similiar to the front or back of a magizine. It had a paper clip and needed some glueing.

Glad to bring a bit of your childhood back! :) I wish the contest had turned out better for you though. If you want to see the original story, I have a link to it on my website

http://www.theonlinepaperairplanemuseum.com/klinefogleman/KlineFogleman1.html

I have another version of the airfoil as well, and there is a link on that page too.

I used to have a plastic toy that was based on this design, and it was actually quite awful, it was much tooooo heavy!
Can you post a video?
deanmackey (author)  Johnsons on fire6 years ago
for some reason, I cannot imbed the video right now.
i have it on youtube at

Of course it helps; especially for a lazy guy like me who doesn't want to read the who instructions ;) Thanks!
I don't mean to be rude but i meant a vidoe of it flying. It would be nice to see it compared to a different tyep of paper airplane
deanmackey (author)  Johnsons on fire6 years ago
Posting one today, I hope it helps!
mmzdaniel6 years ago
im gonna build this for sure!
I love this airfoil, would anybody mind if I posted some other planes using this?
deanmackey (author)  knexgunner946 years ago
I would enjoy seeing more planes with this airfoil. Please let me know when you post them so I can add links to your designs at www.theonlinepaperairplanemuseum.com so everyone can enjoy them! Dean :)

i saw an article about this wing in an early 80s omni magazine. they even had the template printed in two colors on two pages. alas i never made it because i didnt want to cut up the magazine{my ex chucked it in the garbage 10 years later} thanks for the chance to try it again.
deanmackey (author)  lennyb6 years ago
I have a link to a posting of that article, but I have never seen the two color template. If anyone has a copy, I would enjoy adding it to my web site on the airfoil.

They have a great book written about the airfoil as well, called "The Ultimate Paper Airplane".

Both links to the book and the website can be found on my webpage here

Happy Flying!
