GENERAL DETAILS AND BUILD TIPS
There are many versions of the beloved flying wing. This particular model is made from a single piece of Dollar Tree foamboard, pre-covered with packing tape, and assembled with hot glue and two-sided foam tape. Its mission is to go very fast with a medium-sized powerplant and 3-cell battery pack. It is easy to build, with only two straight wing cuts, two hinge cuts, and two score-fold-glue joints for the vertical stabilizers.
The scale and style factor is pretty humble in order to keep the weight down and the build simple, but it can be made to look relatively cool enough with some nice colored packing tape.
Wingspan 21", length 19", AUW 500-650g, speed 60-75mph.
I have used 1100kV and 1500kV 70g, 330 watt +/- motors with 8x6 APC props and 3-cell 2200mAh battery packs and gotten very respectable performance. A 2200kV with 6x4 and a 1300mAh pack was 400g and pretty quick as well.
One could use a higher kV rating and/or cell count for faster speeds.
64mm EDF works very well too, mounted on top, with a paper cup thrust tube.
These can be very fast and nimble with a roll rate over 1000 degrees per second, so I would recommend having at least intermediate skills and low rates to start. Launch 1/2 throttle at 30 degree up-angle and trim while at altitude. The EDF does well with landing gear (nose wheel, tail skids).
Let me know if you have any questions or need help building.

I've flown a lot of foamy's and built a lot of franken planes, but never foamboard built, I've learnt a lot from you , thanks for all the build vids, I'm going to build myself a electric plank with your wing shaping etc, again thank you

@ExperimentalAirlines 11 лет назад

It's just the way flying wings work. Because the rear part of the wing is acting as the horizontal stabilizer of sorts it makes the CG seem excessively far forward.

@edwinkania 12 лет назад

Just built a delta, and love it! Super cheap and flies very well! One of my favorite planes, and im not worried about breaking it! I now stock up on foamboard....

@Elias-Flyingbros 10 лет назад

Thanks for the build details Ed, I built this delta in a couple of hours. I used the turnigy 2200kv and it had crazy speed, nice roll rate. After 20+ flight I clipped a tree at full speed, went into a spin and crashed so hard the lipo went up in smoke and created an awesome display of flames lol! Managed to save most of the equipment, except for Esc. Currently in the process of building another one, might use a landing gear of some type to save on props.

@edwinkania 12 лет назад

Ed, I built this Delta and love it flies like a rocket straight up and slows down for great landings!!!! Im not afraid to fly this in the very frequent winds here in PA! Thanks for the Ideas, keep em coming!!! Ed Kania

@alirangoonwalla9148 3 года назад

I have tried these and I love your design. They are brilliant....

@ExperimentalAirlines 12 лет назад

Very nice, especially coming from another Ed! Glad you like it. So easy to build, and come to think of it you're right, it is a good windy-day backup plane. Be well - Ed

@ExperimentalAirlines 11 лет назад

Very cool, hope it brings you some fun. I generally build with thrust line about parallel to wing surface or just a hair down. Keep your elevon throws down a bit until you get used to it - it's a nimble little plane and can be a handful.

@eglsfootball 11 лет назад

Thanks for the video! Just built the airframe and I'm waiting for the motor and servos. Very simple and fun to build.

@ExperimentalAirlines 12 лет назад

You'll find "elevon" in the menu of the DX6i under "wingtailmix". Turn that on and the servos plugged into the elevator and aileron channels will function as elevons. I generally use the elevator channel for the right elevon and aileron for left elevon. But you can, and will probably need to, play around with the servo reversing settings. Look at the elevons as you move the right stick and be sure they move as needed. Switch receiver channels and/or reverse servo throw on radio as needed.

@ExperimentalAirlines 12 лет назад

Glad you're having success! I've had mixed success with deltas as trainers but you could certainly do as you said, and make a relatively large, lightly loaded, flat wing with upturned wingtips for polyhedral. Nutball sounds good to me.

@vatovega Год назад

I started building Ed’s planes during lockdown. I’m having fun being a kid again

@weldslag 11 лет назад

Ed, I 'm on my third Noob Tube - I fly 'em like I stole 'em. I'm rebuilding my entire foam fleet and didn't know what to start next. Well, you couldn't have made it any easier could you? I've thought about wings but the CG seemed a little tricky. You sold me! When I fly, I often attract somebody who wants to know more. I believe I've sent half of Glendale to your site! This wing is eloquently simple. Nice job. This should pair nicely with my new Alpha Jet. Thanks for doing so much for our hobby!

@ExperimentalAirlines 12 лет назад

I wrecked it handling pyrotechnics a few years ago. My original index finger has been moved to take the place of my thumb, which I lost in the explosion. Many other fractures and problems too. 20 surgeries later it works well enough, so I'm happy enough with it. "Kids, don't play with fireworks ;-) " Also see my "Introduction to Ed and EA" video.

@ExperimentalAirlines 12 лет назад

A little down-right thrust angle never hurts. I recommend either a very steep launch angle with high power, and then just deal with the roll as it ascends, or a more normal launch angle but only half power. The good news is the takeoff rolling is usually brief. If you truly have torque roll through the entire speed range then I'd revisit the thrust angle idea and/or mix in some counter-elevon to your throttle channel if your radio allows.

@TrungHuynh-ol5rk Год назад

Bạn thật là sáng tạo, chúc bạn có nhiều sản phẩm mới

@mercman0071 11 лет назад

I built this in a day and let me tell you, THIS BABY HAULS!!

@drcuffe 12 лет назад

Saw you aerofoil video from flitetest. Love the videos cant wait to watch them all First time I've seen the kissing covering method, can't wait to try it!

@ExperimentalAirlines 11 лет назад

That's great man, it's why I do it! I hope you get over to north Phoenix at the Costco by Cave Creek and 101 and say hi sometime. Yeah, fly 'em like they're $5 is right on!

@ExperimentalAirlines 11 лет назад

I tape the foamboard first, both sides in the case of this plane, then actually construct the plane. It adds a little weight but a lot of strength, but it's still pretty light once done.

@ExperimentalAirlines 11 лет назад

I usually like to go foam-to-foam however this is a relatively broad-based low-stress area so you can probably get by with tape-to-tape. Scotch heavy-duty outdoor mounting tape works awesome as well, more secure than hot glue, in case you want to give it a try.

@ExperimentalAirlines 11 лет назад

You could put in a little right angle if you're really diligent but I wouldn't obsess over it. I mount mine straight. Having the thrustline above the airframe imparts a little bit of downthrust even though the "firewall" is 90 degrees to the deck, so I don't usually put in any additional downthrust.

@ExperimentalAirlines 12 лет назад

Yes, these are nimble little planes, can be pretty sketchy on takeoff. You can certainly adjust your thrust angle a bit. It's hard to dial in the elevons in a way that is good for both takeoff and normal flight, but you could mix the throttle channel into the roll function some counter-elevon. Honestly though all I do with these is just try to take off at half throttle, upwards about 30 degrees, and get stable before hammering the throttle up.

@usarmyfl1 12 лет назад

Thanks again for another great video!

@womackke 12 лет назад

you should add you flight lengths to your descriptions of the planes. awesome plane for a high speed rig!

@ExperimentalAirlines 12 лет назад

I always tape boards before construction. It's a lot faster that way and with some practice you can cover the foamboard in 5 minutes (per side). I usually knock out 10 at a time. There is a video on this channel that describes some tips on how I do it.

@weldslag 11 лет назад

Been to Coyote Basin a couple times hoping to bump into you. Just didn't work out. Flew the wing. Found out Velco is a poor choice for an open fuselage at high speeds. It gets exciting real quick! Good thing these things are cheep. I'll probably start over to have confidence in the airframe again. Fun design.

@ExperimentalAirlines 12 лет назад

The rudder channel is no issue but you will need either elevon/delta mixing on your transmitter or a V-tail/delta mixer onboard the plane to mix the elevator and aileron functions. A 3-channel radio probably does not have mixes so a V-tail mixer for under $10 is likely your best bet. Most sizeable RC vendors sell them.

@ExperimentalAirlines 12 лет назад

Indeed there is no camber. It develops lift from incident airflow against the bottom of the wing only. It's a complicated topic but I can say that sufficiently powered RC models in the size we fly work reasonably well with uncambered wings. Probably wouldn't work well in large aircraft, though there are some pretty thin airfoils out there in some supersonic planes.

@keithfreeman5204 7 лет назад

The Delta wing/Blended Lifting Body has such a wide speed range from a walking pace to out and out blistering speed. The more power you put to it the faster it goes. So much fun. I really enjoyed you video, great ideas and a bunch that I didn't think of before. Cool info. Just a thought.... How about for the EDF, full length "tube', then wrapping the Coroplas around the EDF , install all of the flight controls in the wing? Really smooth things up aerodynamically. . My Delta, scratch built, kinda the same design, just a bit bigger, 48" W.S. 36", nose to tail. Made out of parts of a regular shipping pallet, cut into 1/4 square stock, Winglets bolted to threaded hard points, powered by 2 different engines, O.S. .25 DBB, FX, and an O.S. .40FN. Plain Bearing. Flying with a Futaba 6ch. Throttle, Nose gear, and Evalons. It seems to be very aerobatic. Take off run is about 20 feet.

@MrArcher51 11 лет назад

Thanks. Will try an get some video of the maiden.

@ExperimentalAirlines 12 лет назад

That's going to be awesome!

@ExperimentalAirlines 12 лет назад

Maybe just luck, but I never seem to damage props landing on grass, and occasionally on asphalt. I do program the brake to "on" for all my ESC's that will allow it, for better glide as well as to provide little or no prop rotation on landing. If a blade is hanging down it seems to just pop up 90-degrees and out of the way at the moment of landing. If I'm flying a slower plane sometimes I'll actually tap the throttle stick as needed to place the prop horizontally just before landing.

@LeoTheLegoTV 12 лет назад

Great plane

@ExperimentalAirlines 12 лет назад

There is some definite buzz about using the Armin foamboard folding idea for tapered wings like the Zephyr. Look around RU-vid and RCGroups for "bajiwing" and you'll find some good information so far. I will be doing one pretty soon myself.

@ptstptwi 12 лет назад

Great stuff, thanks for posting

@ExperimentalAirlines 12 лет назад

Great question. When you make an Armin wing or tube fuselage, the warped foamboard becomes irrelevant, since the process changes the shape. For flat planes like this Delta, you really kind of do need a nice piece of foamboard. I usually save the "pick of the litter" for those each time I buy a batch. I do not have any actual methods to recommend to flatten warped foamboard, sorry.

@vatovega Год назад

More experimentation has finally allowed me to lift off... though I'm going to print and glue a ruler next to the battery to adjust the center of gravity. First a nose-heavy flight, next a tail-heavy flight that was hopelessly uncontrollable.

@ExperimentalAirlines 12 лет назад

The smoother and thinner the trailing edge the more "orderly" the upper and lower columns of air can "re-join" behind the surface. Blunt trailing edges lead to turbulence and vortices that create an area of negative pressure behind the wing, tail, or control surface that causes increased drag. How much added performance in a plane like this? Probably not much at all, but I like the idea of optimizing the situation as much as possible for speed.

@ExperimentalAirlines 11 лет назад

I use flat when it doesn't make much of a difference and to keep construction super simple, such as with this fast delta and other light, low angle of attack planes. Using a cambered airfoil has the advantages of better integral strength and way better lift over a variety of flight conditions, speeds, angles of attack. Honestly, RC scale planes are pretty forgiving and you can loft any flat wing with enough power but a cambered airfoil produces lift in a more efficient way.

@orcasea59 12 лет назад

I am really interested in some of the larger, slower deltas that do 3-D style maneuvers. Some of RCTestFlight's planes are interesting, but I would think a cambered delta would be even more impressive! Hope to see something like that soon, but with the finesse & elegence of ExpAir's touch : )

@furballkimfpv9365 7 лет назад

Hi Experimental your video has to be the most informative video so far. Not everyone give's away there secret on building these wings. Sort of have to guess while they build it. I attempted to build one.I just about finished it other than the electronic's part. I have it on my channel if you like to take a quick look and give me your view's on it. There isn't any flaps on it yet or side fin's. Like I said this is my first try. Thank's for a great video and the help your giving us in building one.

@ExperimentalAirlines 12 лет назад

Will do, thanks for watching. This little delta plane is for building fast and hauling ass, and not much more. Big airfoil flying wing is in the works.

@ExperimentalAirlines 11 лет назад

No reinforcement by design, though I have rescued the occasional crunched nose by flattening it out and shoving a skewer or CF rod lengthwise between the wing and 'keel' to keep it straight.

@letmeplaymystrat 12 лет назад

Very cool simple plane Ed. Definitely gonna build it. Looks like it would make a formidable combat aircraft. By the way, you must have an unlimited supply of gift cards :) Cheers!

@ExperimentalAirlines 12 лет назад

Thanks man! Gift cards? Stay tuned.

@Ohdonttellme 9 лет назад

Hi Ed - Thank you for sharing your knowledge and experience in building DT foamboard planes. Question about the Delta Wing project, how do you think adding a KF step would affect the flight characteristics? Probably not needed but always like to modify and experiment.

@ExperimentalAirlines 12 лет назад

Just for simplicity. It pains me a little bit not to have an airfoil but it flies pretty well on just a thin slab of foamboard. We will be seeing larger, cambered airfoil flying wings from me and some other guys coming very soon though.

@ExperimentalAirlines 12 лет назад

AUW 18oz with a 2200mAh 3-cell, 70g motor, and metal gear servos

@argonaut6386 7 месяцев назад

Looks great, I'd love to have a go at making one. What is the thickness of the foam board please?

@thatrcdude 12 лет назад

Shit man that gnarly hope all goes good

@123numidian 12 лет назад

Ed, I built this delta and LOVE it. Fantastic. Thanks so much. Question: I'm a high school teacher interested in starting an AMA sanctioned model club here at school. I flew this thing for the shop class and they went nuts for it. I've seen your Axon video and it's very attractive, but I'm wondering if I couldn't make a trainer delta wing with some polyhedral like the nutball. What do you think?

@ExperimentalAirlines 12 лет назад

Man, that I wanna see!

@gKadonoff 12 лет назад

I've always wondered, why is it better to have a thin trailing edge? If it causes turbulence behind the plane, shouldn't it not matter?

@RusstickDoom 11 лет назад

Hello Ed. Thanks so much for making these really easy to understand series of videos. I have built two planes with your techniques and they both flew great on their maiden flights. Regarding these delta wings, (my next build) HOW DO YOU DETERMINE THE CG?

@ExperimentalAirlines 12 лет назад

Ideally elevon mixing is done via transmitter programming. As another option one can use an onboard mixer but the performance is not as precise. Each transmitter setup is a little different, but typically one elevon servo uses the aileron receiver channel and the other elevon servo uses the elevator receiver channel. I will make an effort to discuss it in a video. Let me know if you have any specific questions in the meantime maybe I can help you with.

@senormiller1 10 лет назад

Great video and Delta, Ed. Your set up looks great… What Turnigy motor did you use, also ESC and best prop. for that set up. Many thanks. Tim

@13orangeleaf 2 года назад

Great videos and instruction! I am not a pilot yet, but was wondering how much this fast delta weighs?

@solarsynapse 5 месяцев назад

2 kewl. How do you know where the CG is? Thanks!

@ExperimentalAirlines 11 лет назад

Tape Brothers com is my favorite source. See other video on tapes on this channel for some other details.

@corsair16 11 лет назад

Ed, With how simple and quick it is to build a flat-plate airplane like this, why do you use the Armin Wing for most of your aircraft? I'm not asking a rhetorical question; I'm seriously interested in knowing, from your experience, what the advantages vs disadvantages of a curved airfoil vs a flat plate are.

@ExperimentalAirlines 11 лет назад

This is not an easy plane to fly. Super easy to build but very fast and easy to crash. I'd start with one of the straight-wing designs like the Axon if you're interested in the foamboard technique.

@phuckeknutz2164 12 лет назад

Could you use a couple of small dia solid carbon rods and glue them on the surface?

@vatovega 2 года назад

I keep having belly landings at launch. I’m using a turning 2200 3S battery. Is it too heavy?

@hunter32195 12 лет назад

YAY! NUTBALL!

@burachattanpradit4450 Год назад

What kind of its airfoil and how did you make it ? Thank you.

@Leigon26 10 лет назад

This reminds me of the NASA X-43 Scramjet

@ExperimentalAirlines 12 лет назад

It's only to get a decent thumbnail. I have not found a reliable workaround for this yet. You should just be able to stop watching when it says "end of video".

@thewillage 12 лет назад

Ed, cool little wing, gonna make one and try it out. How are you keeping from snapping your props on landing? No apparent prop saver.

@ExperimentalAirlines 11 лет назад

I put a link to a CG calculator in the description for this video. Very easy to use.

@MrArcher51 11 лет назад

HI Ed! Love the videos. Just completed a delta wing based on your design. Did you have and up or down thrust angle on the motor or just perpendicular to the surface? I'm here in FL and it is raining :) maybe get out tomorrow and do the maiden!

@nintendogod12 12 лет назад

I made one of these with a 2200 kv motor, and it pulls about 100 mph

@nickatredbox 11 лет назад

great video how easy are they to fly? As I'm a better builder than pilot currently

@THEfromkentucky 8 лет назад

I wonder how this would fly with a second layer on top to create a KFm2 airfoil?

@av8153 12 лет назад

Just curious, why no airfoil on this one ?

@thatrcdude 12 лет назад

Hey i loved your video, just curious about what happened to your hand?

@Voipmonkey1975 12 лет назад

hi ed love this can i ask do you tape the boards before cutting them or after? or does it not really matter?

@MrGarywells 8 лет назад

Great cheap as chips delta....whats your set-up regarding rates thanks

@ExperimentalAirlines 12 лет назад

Dang, that must be a blur!

@maxfig4167 11 лет назад

I have been trying to find color packing tape, and I don't find them anywhere would you tell me where do you find it, because those planes looks real nice with that tape.

@999benhonda 10 лет назад

for a less experienced pilot (ie, me) could you just size down the control surfaces to make it easier to fly? that would in effect tone down the agility and make inputs smoother right? I recently built a much larger delta wing with a 56mm fan. it is not that hard to fly, but is not very fast...almost underpowered due to the weight/size.

@patrick.s.douglas 10 лет назад

There is no need to reduce the size of the control surface to make it easier to fly; you can adjust the servo movement via the transmitter if yours is programable. Another option would be to adjust your push rod to the outer-most hole on the servo horn for reduced movement of the control surface or adjust to the inner most hole on the servo arm or a combination of both. Hope I was helpful.

@Raremuffins1 9 лет назад

I laughed so hard after seeing his little wheel ,,

@dustinhanlin 6 лет назад

I know this is old but I have a few questions so I'll hope for a reply. I built this wing but used a smaller motor. It's a 2204 2300kv motor. Do you think that will be sufficient? I ask because my first attempt at flight with it was an abysmal failure. It could have also been the CG. Does it glide unpowered with the CG at the recommended 7"? I'm fairly new to fixed wings, so I don't know where to start with my troubleshooting. I tossed it with power and it nearly flipped and crashed immediately. Heck, it could even be my crappy launch. Any suggestions on where to start to get it to fly?

@gnomedomegreenhousebuild5570 10 лет назад

what size esc are you using on the prop drive version? love the wing,,gota build one soon

@blakecraig 11 лет назад

just started building one of your tractor delta designs and wanted to know if you added any thrust angle when installing the motor i.e. to the right and down or just simply installed at 90 degrees to the airframe.

@vincepresto759 11 лет назад

I can Not find the build sites I ran across and started one, any helpplease would be great, Thx's Mr Presto

@copyandpastification 8 лет назад

nice video, what servos are you using? thank you

@seeingeyegod 11 лет назад

Does this have no carbon fiber reinforcement?

@ExperimentalAirlines 11 лет назад

Precovered with packing tape. Check out the video on this channel for more details on this procedure.

@wboy3 11 лет назад

do you peel the paper of the foam then tape it?

@vanshsharma1303 9 лет назад

do i require elevon mixing ... and can i use a 5x turnigy mini transmitter for this flying wing.

@ayuminor 11 лет назад

How come the CG ends up so far forward?

@Mr.Mike1 12 лет назад

Ed can you please PM me with the seller's info for the carbon fiber plate? I want try one of these delta wings EDF style. Thanks

@hatzmannhenk 10 лет назад

Hi ed, you mention that the rood chord of the vertical stabilizers is 6 inch as you show in the video. However shouldn't (when drawing/measuring out) the root chord be 6 plus the length of the elevators?

@ExperimentalAirlines 9 лет назад

Henk Hatzmann Aerodynamically, yes absolutely it's the total chord with control surfaces included. For my construction techniques I often specify only the fixed part of the wing as it can clarify the construction cuts and so forth. I usually call it such-and-such an "airfoil chord dimension plus control surface dimension". It's more clear in one way but a little inaccurate in another way.

@abo3rab853 7 лет назад

ExperimentalAirlines hi

@TheGusK 8 лет назад

Very nice vid. Is there a reason why the elevons can't be controlled with a single servo mounted vertically?

@THEfromkentucky 8 лет назад

+TheGusK A single servo wouldn't be able to push or pull them at the same time, preventing them from acting as elevators. If it was set up to articulate them together, it wouldn't be able to move them opposite each other, preventing them from acting as ailerons.

@TheGusK 8 лет назад

+fromkentucky Thanx for the answer as I'm new at this.

@THEfromkentucky 8 лет назад

TheGusK No problem man. Some people do use single servo setups (called "Push/Pull") for just ailerons, it's just difficult to get linkage out that far if you have a large wingspan. Here's a picture: www.wheek.org/macombat/gfx/rapier/aileronservo.jpg

@TheGusK 8 лет назад

+fromkentucky Now I understand. Thx again. Going to build one of these, need a break from quadcopters. :)

@mercman0071 11 лет назад

Hi Ed, Great video series. Regarding the keel, do you hot glue it down directly on the taped board or remove the tape/paper and glue to foam? Thanks again!
