Easy Foamboard Wing Airfoil: the Basic Version
HTML-код
- Опубликовано: 24 авг 2024
- Part 0 (a basic intro to the Armin Wing concept). A really quick and simple way to build an actual airfoil for an RC airplane wing. For a rectangular wing it's at least as easy to make and as strong as a KF airfoil and has the proven high-lift design approximating the "Clark-Y" airfoil used on many real and RC airplanes. Videos to follow will include improvements that take a little extra time but will make the wing more aerodynamic, water resistant, and have an integral control surface for flaps and ailerons. This is just the wing construction - overall airplane design is up to the builder!
Here is where I get my colored packing tape:

Was just taking a RUclips stroll down memory lane to revisit where I started building planes and Armin wings 11 years ago. Thanks for the inspiration and enjoyment I have had with RC planes that you inspired. It’s great to see all the views this vid has gotten.
Excuse me, what is the material that this man used in the video?

I built 2 planes with this same wing and covered it with packing tape . They fly brilliant. The best wings I have ever built, well done Edd, thanks for showing
Excuse me, what is the material that this man used in the video?
I have just recently started building my own rc planes and found this channel. The basics that you have shown my are awesome. I have build 3 different size planes with multiple different wing configurations for each fuselage. It has given me something to do during the winter here in Pa. Thanks, now the snow has to melt so that I can start flying more!
Doing the same in the UK.
Thank you for this! My little son has been pestering me to build a wing that would actually generate lift. He tried to make one out of cardboard, but of course it's not the right material. Now I can at least build a wing with him!
Aww
I dunno if Google just did some kind of update to the algorithm that finds content that I'm interested in but lately I have found sooo many new channels that are awesome. This is one of em!
watching your videos since day 1 you have made a major contribution to the hobby for young and old ! god bless you 😀. i'm 78 and still learning, ... clear skies and fair winds - jos 731
Almost 40 years ago, about 12 yo I built a balsa control line trainer without plans using almost the same method. Of course Balsa can't be so easily bent around the leading edge (LE) radius like foam can. So, I just used 2 sheets of 1.5 mm balsa, glued a strip along the edge of one sheet and planed down the top of that strip at an angle. Then glued the other sheet to the angled top of the strip. This formed the LE. Next I just brought the 2 other edges of the sheets together with glue to form the trailing edge (TE). Added tip plates, attached a flap to the TE and sanded the LE round. That's it, no internal structure. Added a stick fuselage, tail surfaces, OS Pet 1.5cc glow plug engine and external controls etc. It was good because I had struggled with a stunt model that I couldn't master. This simple, quick and easy build and got me flying CL on the 1st time attempt. So thanks for bringing back the memories.
Yes, with a carbon arrow shaft for a spar I can confidently recommend this wing for heavy planes and aggressive flight. I have an "aerobatic" motorglider with a 60" wingspan that I abuse pretty frequently with high-G maneuvers and it only causes a small crease in the upper wing skin near the root. My 60" wingspan Skyvan II weighs 9 pounds all up, with cargo, and does well with one carbon arrow spar and wing struts.
this the easiest way to make wings I have found so far,dollar tree down the street from my home picked up some foam and in five mins. I had a wing all ready to go,thanks for all those videos
I've found that peeling off the paper and using a hairdryer to bend it works perfect, no kinks. Then cover with tape. Also if you look at airplane wings the leading edge is always "Chubby".
@RCPrairieFlyyer That's great to hear! I hope we can see your creation soon. I wish you blue skies and warm fingers!
Fantastic videos and easy to follow. I built my very first Armin wing today and WOW, I can't find the words to express how well your build techiniques worked. In Canada, it is of course winter now and with your helpful videos, my friends and I will have a new plane to fly in the snow.
Just found your channel and have turned off my TV and am going through your videos :-)
I have just started foam building with a MickeysRC unit that is giving me motor thrust angle issues and in search of education I found you.
Thank you for the information, I will pay it forward.
All I can say is ... WOW... very ingenious. Thanks for your time and skills.
I've watched a few of your videos & wanted to thank you for the amount of information you share. I would like to watch more of your videos on building foam wings if you could direct me on the easiest way to find them. You really do give a good presentation. Thanks again.
Thank you that you give american AND european data (grams & oz) :D
when?
notta clue but it has to be a lot lighter then my all balsa and 1/32" spruce plywood plane.. but mine have actual structure inside the wing.. (2 1/4" thick spruce bars down the entire wing and ribs to keep the form of the wing.... how real aircraft are made :-\ ... 3 months build time for a 60 inch wingspan plane :-\.. think I'm try this stuff.
THese are great.
Ive been using the 'electrifly' brand hobby foam (very light x surface tension loading) and 'ribbing' conventional rib style build with a single carbon fiber main spar...made a 2-meter wing with 9 inch chord and 1.5 inch thick rib profile...(clark - Y flat bottomed airfoil) even added "twist out" camber at each wingtip for minimizing tip stalls. Whole wing with 2 mini servos for ailerons/flapperons weighs a couple ounces. Yea...wing loading is super light, but its a light plane.
Hi and thanks for your replay....I'm digging in to it...
Happy flying.
Chers

It's a complicated question, but as a general rule 1:1 will nearly always do you right if your vertical and horizontal stabilizers are adequately large, like 10% and 20% of wing area, respectively. A 1:0.75 wing:fuselage ratio is still pretty good, same concept applies about making the tail surfaces generous. I have personally never gone past a 1:0.67 ratio and made the stabilizers plenty big, and needed active rudder control to fly. I'm sure there are entire books on this subject. Cheers!
If you can run the foam inside the foil shape upright on edge you will substantially increase the wing strength.
Fill with expanding foam and carve off the excess. Making something similar with my son using aluminum flashing for a windmill airfoil
This is very very elegant solution . Slap yourself on the back for such a nice solution & being kind enough to put it up ........... now the question is , can I get foam board in 30 ft lengths !
Haven't seen much of Ed lately, miss his great training videos.
I guess if this concept would be upscaled, you could even make very large drone wings with that. Like using Epp board with a thin glass layer.
I am feeling bad because of your hand. And you are doing a fine work. I wish you everything good in your life.
Thanks for an excellent video! Very well done and straight to the point without a lot of dancing and music LOL. Looking forward to finding some more of your videos
Necessity is ""THE MOTHER of ALL INVENTION"! Keep up the GOOD Work
Thank you for your well thought out video. You display a superior format in these productions that is so helpful to those of us who are serious in learning about R/C topics. Bravo!
Had to subscribe... Just saved me a whole lot of money on making my own wings. Thank you!!!
Nice, I am justing starting to work with foam board and thought your VIDEO was Great!! Im trying to build a ULTIMATE with Foam Board and this method of making a wing is the ticket for me!! Thanks!!
This is genius. Ive seen people hot wire cut airfoils but i find folded airfoils easier to make. I kind of developed my own folded wing wich is a mix between this and flitetest styled wings. Hopefully i can make a video on it soon.
There is no absolute rule but it seems to work out that a fuselage length that is 70% of the wingspan is a good sweet spot. Shorter tail needs larger horizontal and vertical stabilizers, longer tail can have smaller. If you had to pick one ratio to start with I would use a 30" fuselage and a 45" wing.
ExperimentalAirlines - Thank you for posting educational and entertaining "build videos"
These are so excellent..........
I'm keen to know more about the control surfaces and how to integrate them.
the basis behind it is to change the lift to. faster airflow over one or the other side literally pulls it that way. as for the size of the surface... thats complicated aeronautical engineering.
but any case, no less then 1/4 length of wing and no more then the whole wing... how long it is,, up in the air depending on type of airfoil. but if you make it to big they flutter at higher speed and screw up speed...
lol not to mention the servo might not be strong enough to move it when the wind is pushing on it... locking you controls up = slow speed nah... but high speed uh oh. no control..
I would be happy to help YOU do such a video, and I think it's an excellent project! Let me know how I might help or sponsor you.
No NACA airfoil specifically, though it comes out to about a 5410. It's a good all-purpose airfoil but does have a flat bottom. The ease of build is the real attraction and it works pretty well on RC with low Reynolds numbers and the ample power we use. There is the possibility of making symmetrical and semi-symmetrical wings but making a well-matched pair can be tedious.
Skydiving with Danes, Mexico beer, Ecco sandals..... that explains the well flying crazy designs. :)
Great technique! Thanks dude for sharing. I just started using a similar technique for a 120" span glider I'm building. Love using the foam board & hot glue.
Unfortunatly the foamboard in the uk is better quality and the paper wont peel back as easily as yours! Making it impossable to get a nice curve!
nice to see you willing to help your viewers.
That's so cool looks simple and I've got to try it. Now I'm going to be able to build moor or less any plane i want. Thanks
I love dollar tree foam board. I use it all the time for my scratch builds and when you wreck you plane, which you eventually do you just go out and buy some more foam board and build a new plane. As long as your electronics are in good order you are good to go.
We are using illustration board for the air foil and to move the flap we are using syringe and surgical hose.. And i cant find any videos like our project..
Definitely will demonstrate lift. A flat piece of foamboard kind of would too if you had the right angle of incidence, but I think you want to show the actual cambered airfoil lift effect, so this would be a great way to demonstrate. I think you would need at least a simple rig that slid or pivoted up and down to allow the wing to lift up and down. It would take a pretty serious airflow to cause enough wing flex to be plainly visible. Let me know if I can help. Science project?
That would be a pretty tight airfoil at 7cm. The upper and lower layers of foamboard would be 11mm alone. You could strip paper off and not apply tape to save weight, but the wing is more durable with the paper and tape.
I'd like to see how you add dihedral to the wing using foam board?
Thanks
Jimmy, ARRL TS, WX9DX
Thank you for making this video! I will try to make my first wing using your method and materials.
By the way, the foam board I bought to make my fuselage with I got from Lowes home improvement. I got a 4x8 ft x 3/4 thick for about $10
Its blue and its super light but very rigid.
Great clear instruction and method, please post more on any good ideas you have.
I follow that. I do use something like that for the leading edge of horizontal and vertical stabilizers. I see how it could work for the trailing edge of a wing, or maybe squish it up into the hinge of the control surface. Give it a try and let us know how it works out.
Nice job! Everybody should to complain how is expansive buy a airplane. I can understand a simple airplane cost the same price the one TV 32" or TABLET.
Probably one of the best inventions in rc history...in my opinion.
johnny llooddte lol this is used in any wing on real planes lol that isn’t an invention of rc
Great public site, especially for beginners alike myself, thanks to the individuals and You Tube. Keep up the good work! !!!
Outstanding construction idea. I see potential for taper airfoils and larger wings.
I'm planning a faux Telemaster in foam. I think a 7" chord 4 foot span will be nice and I will likely use flaps so the thing can back up in the wind.
Awesome work ! I do a similar thing but thinner strips. The strength seems to come from my tape even better !
You're great man! really nice and well done videos, specially for someone like me that is trying to built my first RC plane from scratch. I'll do it and let you know the results, but keep them coming please. Thanks for you time.
Results ?
I recommend starting with the video entitled: "ARMIN WING CONSTRUCTION: start-to-finish process with links to detail videos", which has embedded links for each of the sub-steps.
Excellent video. Well presented, clear, concise and with all the important details. Well done!
Back in the 1970's there was a small one man 'ultralight' powered aircraft called the "Cri-Cri". It was built using some kind of similar (ultra simple, yet ultra strong methods and materials, and it might be worth researching , to find out if there might be some lessons to learn on how to build precise, yet super strong wings, (or even rotor blades?)! I remember an article about it saying that the builders 10 year old daughter built the wings for the plane, and that it involved using some kind of 'vacuum cleaner' to help hold everything in place (like a crude 'vacuum-bagging' technique) though the wings were made of thin metal, over a foam core, (perhaps with an aluminum tube, as a central spar)? [Thanks!]
Great video, thanks for taking the time to do this. There are so many ways I can see that can be done to reinforce this, awsome. Probably easy to add a channel for carbon spar etc. Also wanted to mention the use of the laminating film for covering, low heat easy and really cheap stuff.. Again great explination and thanks for taking the time to share..
I am quite interested in experimenting with wing designs and slow speed flying. This gives a great opportunity. Great video. I think you are onto something. ha ha
OK up to something. Happy landings.
No, I like to leave the paper on for durability and strength. The tape adheres way better to the paper, permanently. You can strip the paper to save a little weight but the tape adhesion is not great.
Very cool. Be great to see a glider, or self launching glider made from this. Plus I have some softer blue foam that might be fun to try.
The sky is the limit
Thank you so much. Was trying to make a mini airomine wind generator.
Seriously man, you need to give me more than a couple of hours to respond. Readi-Board is 5mm nominal thickness with paper on, can vary by about .2mm
Perhaps these surfaces could be covered/wrapped with strips of clear 'packing tape' - which is very thin, yet smooth, and very strong! That might make the wing very resistant to moisture/water, and lower the surface friction/drag (?), Or, wrap it in thin 'Dura-cote', or Mylar type of heat shrinking film, and shrink it with a small iron.
This also seems like a great idea for making prototype wind turbine blades.
Thank you for this very helpful tutorial.
As an aside, your voice/accent is sounds very similar to Carl Sagan.
I made 2 of these and they turned out REALLY nice! Thanks for all the great videos- I finally subscribed after watching so many and how impressive my wings turned out. When are you going to have another contest? Love some of the entries! Thanks again!
Dollar Tree (Readi-Board) foamboard is 5mm thick. The 5" and 7" chord models I detail in the later Armin Wing videos are all-around general purpose airfoils with 11% thickness at 40% chord, similar in use to a Clark Y, but not the exact dimensions. You can easily change the thickness and camber to suit different needs. There is really no meaningful analogy between a conventional airfoil and the KF with regards to dimensions. If you have a specific need in mind let me know and I might help.
You will get better rigidity if you make vertical spars instead of stacked foam.
I've left the board out in the rain for days at a time. I weighed how much difference there was with/ without paper and it halved the sheet weight.
Thank you for this video. I've been building foamboard hand gliders for my kids, and apparently I wasn't smart enough to do this. I've been sandwiching 2 or 3 identical pieces together with glue and hand sanding the airfoil shape out of it. Not quite as efficient as your method, and yours is certainly lighter to boot.
Thank you for this technique.... I hope to use this technique and cover it with foil tape to make my planes. I want to make my plane bodies from metal (I'm very familiar with metalwork as of yet, not at all with foam) but I need something to make wings.
just picked up some adams board at the local dollar tree. i plan to make this wing. thanks for the video !
@bendunia It would make me extremely happy to see that video! I and some other guys are having good success with the Peace Drone for FPV flying. It is not hard to build if you can find the right foamboard. When you do, please tell me where you got it so I can help other builders around the EU. I'm sure you'll also appreciate the canard design - a French word and a French invention! Also see video for Armin Wing part 9 for the accidental French flag in the thumbnail.
It is 5mm thick with the paper facing still on.
your videios are so to the point . nice job
Brilliant.
I'm interested in the plastic covering and wing extensions.....
Have had the worse time trying to find a covering here - use vinyl to cover my folded wings but the hot weather here bubbles the vinyl sheets and the model ends up looking like a seen from the moon landing . Hopfully I have resolved the problem with Kodac vinyl pro film 60 pence a meter .
Like your videos. keep up the good work. You just opened my eyes to alot.
Thanks
Keep'em coming great stuff this is just what i needed to see.
@carstensonderskov It's called "foamboard" or "foamcore" and can be found at many craft stores, teacher supply stores, and photography supply stores. Can't post a URL here but Google "dollar tree foamboard teacher" and see Readi-Board there. In EU you might be just fine using Depron with tape reinforcement. It's too expensive here. US$1 for cheap foamboard with thin paper is great value here. If you find it be sure the paper is thin and peels off easily.
Cannot get it online, and there are no Dollar Tree stores in Georgia (country). Look around for some other light foamboard 5mm, ideally with the paper easily peeled off. Depron is another option.
I love this channel, flitetest sent me here :0)
Yeah, Physics, 9th Grade. We want to build an undercambered airfoil to ensure maximum lift generated from the air blown using a simple table fan. Will this video's instructions help in making an undercambered or is there another? Thanks though. Glad I found your videos. :)
thx ,.... im seen most your videos and FT videos... still trying get a wing that's very slow/ stable for videos. im using the ft exployer frame-thinking put your type 7 inch wing on it! maybe 4 formers and shaved more on edges and tapered trail ends .. no flaps... just 3 channel. /smooth flight. maybe oversized end caps for the wing (stable ).my first wing /haven't tried yet! its top sheet and spars only/ open underneath.. catches wind like a kite! 2 - 3/16th thick bar b que sqeers! hopes it works.. kinda glue globbly messy- . need a cleaner way to make it!
Dollar General stores also carry the same foamboard they have it in black too
Will this be light enough to demonstrate the concept of an airfoil? i.e. to show, using a simple table fan, how the wing creates lift to make an airplane fly. So, what I'm wondering is that if I blow air onto the airfoil, will it show enough wingflex to show that concept?
Great video. Looking forward to seeing more.. Thanks
Very informative! Great job! Thanks for posting this.
Hmm, then IM is out of the question, as that is 10 PM to 5 AM in my timezone. So, just two quick final questions. What can I use to generate enough airflow in a classroom to clearly show wingflex? And, since I want to show maximum lift with the kind of airflow I'll be able to generate in a classroom, can you make a video showing me how to make an undercambered foil?
Any videos on measuring airfoil angles and stuff? I'm trying to learn this stuff
So many show foam board creation for mostly larger aircraft, BUT what about that foam ( design) on a much smaller scale like UMX size ? I see few to none who have built smaller aircraft with foam ( not saying people don't ) just saying very few show they do and the technics they use to accomplish their build
Example a Guillows size balsa plane is probably nearly the same weight as a Foam of the same size/style I would assume ?
Any advice/wisdom on the subject ?
Great video, just came into my feed. Going to try it.
Awesome job. Thanx for passing this info on...
if you reinforce this with carbon fiber, it would be rigid enough to carry a significant amount of payload without bending right?
nice!.. thanks for my winter projects.
Wow! That was pretty simple. Thank you and more please!!!!
