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.
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
coming back to this video almost ten years later to find this legend is still posting new stuff! I used to build these with my dad and now I'm building them with my friends, thanks for years of fun!!
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!
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
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.
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!
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.
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
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!
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.
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.
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".
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!
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?
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.
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.
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.
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.
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.
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.
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.
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.
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!
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!!
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.
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 !
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.
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
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.
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..
@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.
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.
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..
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.
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.
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.
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.
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.
Hey Ed, just inspired to follow one of your designs and starting here at the basic wing. I'm planning an FPV Night Flyer with forgiving characteristics and payload for Go Pro, Flight Cam, OSD, AP and I'd say 3S 2200 lipo should be fine with maybe a 1300KV motor and 9X6 prop. Which of your fleet would you suggest? Many thanks - love that Burning Man video btw... :)
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!]
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. :)
@Cork42044 Thanks man, let us know how it works out. I do not have plans for the cargo dropper but hope to have some plans for something close to it soon.
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 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.
I think I would keep a model that size about 8-10oz overall weight, but so much depends on the design and your skill levels, so it's hard to give a definite answer. 4oz seems a bit heavy for just the airfoil. What's the material and does it contain electronics with that weight?
Tips: The paper comes off much easier if you mist it with a water spray. The paper should be removed from both sides, then the tape applied, then bend. The results are better. If you leave the paper on, it will NOT be waterproof and even high humidity could cause it to peel off.
@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.
When you cut your trailing edge to glue it down, couldn't you also score that lower piece of foam board further out by an inch of so longer than you did and then remove the foam from it and use the remaining paper left there to pull up and over the trailing edge to glue it to the new wing surface? Hard to explain, but it just seems like it would work if the original foam board is cut and scored to allow the extra at the trailing edge. Great video. Have you made another to cover trailing edge?
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?
thanks man. I subscribed because I love the work. I'm a relatively new scratch builder, have 2 airplanes now. F-18 and P-40 as scratch builds. Would like to make your airfoil for a glider. I have searched for airfoils around the net but never knew how to make them because I didn't really know of any rule of thumb or anything to gauge when making airfoils for different planes.
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..
@Snoppus Hey, that's a brilliant idea! Did you also tape the outer surface of the bend? If you can describe it a little, and define the depth of material removed, maybe I can add a Depron version video.
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.
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?
Great wing. I will be building some of these I am going to put it on the Puddle Monster to see how it flys over the build up wing.that is in the plans this is a lot easier to build. Thanks, PS do you have plans for the C-69 cargo dropper? Duane
Hello from Germany. I like your videos, especially watching you experiments and techniques witch cheap foamboard-constructions gave me new insights in the hobby (I am doning that for nearly 40 years now). I want to do a twinboom this winter for FPV with this way of construction. Question: Did you ever build a biconvex Arminwing? Greetings from GER.
oh my thanks for all the work! It's amazing. Can I ask something? Based on KF airfoils, there are specific dimensions which will produce results for different applications (Glide, speed, normal etc...). So for this airfoil, how would you know what to make? or would you make one with close reference to the data on kf airfoil? Also, how thick is that foam? Thanks :D
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!
I'm doing a science fair project on how the thickness (camber) and the cord length will effect the lift of a wing. Could you make a video with 4 wings. All with different variables?
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.
I really wish that foam board, powerful and light batteries and foam board were around when I was first getting into the hobby. I liked building the planes, but nitro engines were a pain and I was poor and scared to death of crashing something that I had so much work into.
Dude, thats great. Thanks for sharing. Im in the process of building my first foamie. I own a few super cubs and that the basic style Im going to build. I already made a great fuselage and now your wing idea will be next. Thanks again. By the way, I see you made several, have you used any and flown any.
Hiya Matey!! a real good one, Could ya pls let me know the name of the tape you used and where to get that! I mean the colored ones that you have stuck over the foam board. I would appreciate if you could let me know!! Cheers now!!

Necessity is ""THE MOTHER of ALL INVENTION"! Keep up the GOOD Work
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.

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.
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
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

nice to see you willing to help your viewers.
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 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..
ExperimentalAirlines - Thank you for posting educational and entertaining "build videos"
These are so excellent..........
Awesome work ! I do a similar thing but thinner strips. The strength seems to come from my tape even better !
@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.

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..
Great clear instruction and method, please post more on any good ideas you have.
I'd like to see how you add dihedral to the wing using foam board?
Thanks
Jimmy, ARRL TS, WX9DX
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!
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..

Results ?
Excellent video. Well presented, clear, concise and with all the important details. Well done!
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.
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'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.
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
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.
Hey Ed, just inspired to follow one of your designs and starting here at the basic wing. I'm planning an FPV Night Flyer with forgiving characteristics and payload for Go Pro, Flight Cam, OSD, AP and I'd say 3S 2200 lipo should be fine with maybe a 1300KV motor and 9X6 prop. Which of your fleet would you suggest? Many thanks - love that Burning Man video btw... :)
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!]
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. :)
@Cork42044 Thanks man, let us know how it works out. I do not have plans for the cargo dropper but hope to have some plans for something close to it soon.
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 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.
Thank you for making this video! I will try to make my first wing using your method and materials.
It is 5mm thick with the paper facing still on.
I think I would keep a model that size about 8-10oz overall weight, but so much depends on the design and your skill levels, so it's hard to give a definite answer. 4oz seems a bit heavy for just the airfoil. What's the material and does it contain electronics with that weight?
Tips:
The paper comes off much easier if you mist it with a water spray.
The paper should be removed from both sides, then the tape applied, then bend. The results are better.
If you leave the paper on, it will NOT be waterproof and even high humidity could cause it to peel off.
@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.
When you cut your trailing edge to glue it down, couldn't you also score that lower piece of foam board further out by an inch of so longer than you did and then remove the foam from it and use the remaining paper left there to pull up and over the trailing edge to glue it to the new wing surface? Hard to explain, but it just seems like it would work if the original foam board is cut and scored to allow the extra at the trailing edge.
Great video. Have you made another to cover trailing edge?
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?
thanks man. I subscribed because I love the work. I'm a relatively new scratch builder, have 2 airplanes now. F-18 and P-40 as scratch builds. Would like to make your airfoil for a glider. I have searched for airfoils around the net but never knew how to make them because I didn't really know of any rule of thumb or anything to gauge when making airfoils for different planes.
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..
@Snoppus Hey, that's a brilliant idea! Did you also tape the outer surface of the bend? If you can describe it a little, and define the depth of material removed, maybe I can add a Depron version video.
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.
Skydiving with Danes, Mexico beer, Ecco sandals..... that explains the well flying crazy designs. :)
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?
Excellent video tutorial. What is the smallest size of wing for this method to be effective?
Thanks
Alex
Readi-Board is just about 5mm thick with paper on.
Great wing. I will be building some of these I am going to put it on the Puddle Monster to see how it flys over the build up wing.that is in the plans this is a lot easier to build.
Thanks,
PS do you have plans for the C-69 cargo dropper?

Not available online as far as I know, but you can get single sheets at The Dollar Tree.
Hello from Germany. I like your videos, especially watching you experiments and techniques witch cheap foamboard-constructions gave me new insights in the hobby (I am doning that for nearly 40 years now). I want to do a twinboom this winter for FPV with this way of construction. Question: Did you ever build a biconvex Arminwing?
Greetings from GER.
oh my thanks for all the work! It's amazing. Can I ask something? Based on KF airfoils, there are specific dimensions which will produce results for different applications (Glide, speed, normal etc...). So for this airfoil, how would you know what to make? or would you make one with close reference to the data on kf airfoil? Also, how thick is that foam? Thanks :D
Depron is relatively harder to use by this method.
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!
This is helpful... doing a winglet vs. standard wing science project. is there a way to add a winglet??
I'm doing a science fair project on how the thickness (camber) and the cord length will effect the lift of a wing. Could you make a video with 4 wings. All with different variables?
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.
I really wish that foam board, powerful and light batteries and foam board were around when I was first getting into the hobby. I liked building the planes, but nitro engines were a pain and I was poor and scared to death of crashing something that I had so much work into.
Dude, thats great. Thanks for sharing. Im in the process of building my first foamie. I own a few super cubs and that the basic style Im going to build. I already made a great fuselage and now your wing idea will be next. Thanks again.
By the way, I see you made several, have you used any and flown any.
just picked up some adams board at the local dollar tree. i plan to make this wing. thanks for the video !
Can't wait to try this. Is your left hand the result of a nitro hand start?
Thanks for the video. I learned a lot. When building a propeller plane, what is the recommended wing span to length of plane ratio? Thanks.
Hiya Matey!! a real good one, Could ya pls let me know the name of the tape you used and where to get that! I mean the colored ones that you have stuck over the foam board. I would appreciate if you could let me know!! Cheers now!!
Any videos on measuring airfoil angles and stuff? I'm trying to learn this stuff
