What Is Dihedral? How Does It Work? When To Use It?

[@RealEngineering]

Love your videos! Was planning to do a video on this concept at some point myself.

[@fully_retractable]

Love your channel as well sir.

[@SamuelWallsJames]

You were the only person who managed to get me to understand this properly, thank you!

[@partsbenttoys]

Thanks Ed, even yrs latter I can come back for an over view. cant tell you how much your vids have re-newed my interest in the hobby. cheers

[@crazycrow3378]

When I first started flying I was actually not a big fan of using rudder. I learned flying without using it at all. Later on when I flew my first plane with a flight controller I found out the real advantage of using the rudder. After this video I concluded I'm gonna have to scratcbuild an aileronless dihedral plane just to get a feel for what it's like. Thanks for the inspiration.

[@royalbirb275]

using this to study for my commercial single-engine ground course, and it helps a lot, thanks!

[@ruprechtrw]

Thank you. I've learned much today.

[@StephenTack]

Thanks! This clears up some confusion I had after being told the "tipped wing lifts less" myth.

[@prinecash]

Very interesting--many years ago when I was experimenting with glider models it always seemed that adding dihedral made a difference.You did a very clear and knowledgeable explanation. Thanks.

[@cybrunel1016]

Great stuff. I enjoyed the way you went in depth without overwhelming us. Kudos.

[@bearcat8691]

Great video as usual, Ed! That's the best explanation of the function of dihedral I've ever seen! Keep up the good work! Thanks!

[@tommuhlemanjr.3871]

Very cool video! I love to see you flying and making videos again. I've been a licensed full scale pilot for 30 years and I still learned a couple of things (of course, depending on which lift model you subscribe to). Anyway, keep the videos coming.

[@sanjeen2503]

You explain nice, especially with the "wind's view of the wing". Liked!

[@wassafakhtar2262]

Dihedral is great for Lateral stability . Love this Video . This Concept saves a lot of Money and Work ,When its only 3 Channel .

[@blackmennewstyle]

Thanks for the great explanation :) Enjoy the rest of your week

[@markhondaturbo]

great video. the plane you were flying sounded really cool, like a 4 stroke gasser. very smooth, too.

[@quiet_paradox9830]

You just saved my Flight Dynamics grade. Thank you

[@syedabdulsami7759]

You have great explaining skills.

[@vijaysharmapc]

The Best Explanation.

[@SR-ge1ci]

clear and simple, love it! thank you

[@brianemery8945]

excellent explaination. and your airplane designs are beautifully simple. i just wish i found your channel earlier!

[@robertbrunston5406]

Thank you for your explanation and demo.

[@iman80skid91]

Nice video... Thank you... What motor do you have in that plane

[@umutdiksac3649]

Amazing video!!! Thank you for sharing. GOOD JOB:)

[@brettsgalaxyvids]

Great video......Keep em coming!

[@mattvelasquez5510]

good video thank you for sharing

[@garystephenson8063]

I like all your video. and like all the training you give. I have build a few of you tube and they flight great.. keep up the good work...

[@JoMariAltez]

nice so far this is the only video i saw that have a working rc plane with no ailerons, i got a project and my question is it possible to make a plane that can only go straight with only motor and battery

[@thenatedog]

I have a big 3 channel plane setup for fpv chasing. Its nice because when you want to use pan and tilt you dont have to worry about also keeping the wings level. On a 4 channel plane i have a hard time using pan/tilt without a flight controller keeping the plane level.

[@dudulin1359]

Nice video! But can anyone help me with 4:40, just don't understand why will the wing have a higher AOA at leeward side, thanks a lot!

[@61066clocks]

Thanks for the vids Ed, also enjoy the content

[@foxbodyford]

Appreciate the video.

[@steamingbob]

Good simple explanation

[@thomasanil488]

AMAZING WORK!!!

[@INDIRC1]

Amazing work bro

[@gke3800]

Where is that noise coming from - resonance or prop balance? Good explanation of dihedral though.

[@JByrneMon]

Good video. Could you explain why adding dihedral would fluctuate the change in lift due to a forward velocity perturbation? Its often considered a negligible effect but I can't wrap my head around it.

[@mountaindewdude76]

That's too cool! My Dad would probably be able to benefit from a plane like this. That plane....is that just an elongated Noob Tube? Great video, Ed!

[@mmatt334]

I'd like to see more videos like this explains more laws of flight as I am an avid flyer and foam board builder

[@SnapPunchRobert]

Very informative video. I've always wondered how that worked. ??? -- -- I have a question. What is the upside or downside of having Dihedral in your wings like that and having Ailerons ?

[@pirateman1966]

Great educational video Ed. Would you be able to make a longEZ model, or some other canard design with your construction techniques?

[@garymanning8920]

Excellent

[@q300SBB]

Great job Ed. Is it true that with a rudder induced turn, say to the right, that the left wing would have a momentary increase airspeed, resulting in a subsequent increase in lift, thereby raising that wing? The secondary effect of yaw being roll?

[@ThKattmann]

This guy is F'n Great !!

[@Jessewren1968]

What plane is shown at the beginning and end of the video?

[@FlyingMerf]

Great video as usual. I have one small difference of opinion however. The different magnitudes of the VERTICAL COMPONENTS of lift from each wing plays a role in righting the plane, in addition to the yaw-related effects you explained.

[@albensmaine3057]

hi man , i have been building so many rc planes and most of them don't even glide properly , i want to make this exact plane do you have an tutorials or tips on how to make the wings and what dimensions for the whole plane ? and how much does it weight ? to be honest we have to present our school project plane but it doesnt even fly ..

[@INDIRC1]

What is fuselage material?

[@daleharrington5936]

Great Video. Wrapping my head around if i save electronics. I can have a new plane every week. Time and a buck a sheet.

[@yassermasood9798]

very educational video

[@danogle9927]

Excellent, thank you

[@jeffs7915]

Doesn't a higher AOA cause greater lift and drag? The drag causes the the higher AOA wimg to stall leveling the wing.

[@nadeemimran6295]

How does the angle of dihedral effect the plane's flight and what is the best angle

[@AnthonyvanHamond]

extremely good and clear video!!! great work!.. btw your electric plane kinda has the farting sound of a muffled gasser. is that because of the fuselage-end or the prop?

[@thedogewilleatyouwithranch9393]

I think he needs to balance his prop

[@nikolatotev]

Hi, I am new to the hobby and I was wondering if I can retrofit ailerons to dihedral?

[@kertatthedisco8253]

3:54 How does the upwind wing incur a greater AOA than the downwind wing?

[@bridlingtonengland75]

Was thinking the same thing, but I only think this occurs 'as it is moving' which would make sense. As the wing moves down, its angle to the relative wind must be increasing. At least I think that is right?

[@kertatthedisco8253]

+bridlingtonengland75 I did some research and I think it is important to know first the direction of the relative wind so you can fully visualize how the other wing has a higher AOA than the other. Here, check the answer with the pink airplane. aviation.stackexchange.com/questions/26759/how-does-the-dihedral-angle-work

[@iforce2d]

I think he means when the wingtip of one wing moves forward due to a yaw change, it will present a more sloped surface to the oncoming air than it does when perpendicular to the airflow. That is, instead of the air moving directly from leading edge to trailing edge, it will now also move slightly spanwise, from the wingtip toward the wing root.

[@bobu5213]

So if it creates more lift on one wing won't that create a positive feedback loop of lift on one side and knock the plane over?

[@DEeMONsworld]

Aerodynamic forces on a complex shape as in an air frame are many and interrelated. Your explanation is what I would call an excellent middle ground between a simplistic somewhat erroneous description, and an over everyone's head mathematical treatise. In fact the second biggest influence on an air frames relative dihedral is a largish square fuselage shape. So boxy trainers have a greater relative dihedral than a sexy rounded and or blended fuse, and if that fuselage also has an airfoil shaped profile all the more streamlined and an effective lift generator it becomes. A good example in the full scale homebuilt category would be the Wittman Tailwind. It is a small boxy plane capable of 200MPH speeds.

[@MatthewHeiskell]

Dihedral also raises the center of lift, which provides pendulum stability.

[@kevinhainline8232]

pendulum stability isn't a thing. Not for free-flying air vehicles at least. If you draw a free-body-diagram this should become apparent

[@barny-6727]

Kevin Hainline why? Moments about CG?

[@kevinhainline8232]

exactly. your lift always goes through the CG, so disturbances in attitude don't cause a response in the moment about the CG that would rotationally accelerate the vehicle back toward level. tom stanton has a good video about this

[@stickmixfpv188]

Great explanation of dihedral! Education on high level! 👍 But why does the plane sound like a chainsaw? 😂

[@punitprakash4287]

What if we check dihadral for VAWT

[@latifsaifudin1463]

size wingspan and fulsage sir?

[@brijeshsrivastav1992]

Actually I am planning to make a bicopter quinjet with both fixed wing and free wing abilities. Now the original avengers quinjet has an anhedral angle, so I wanted to now if it in anyway effects the ability of the quinjet.....pls help

[@aeroengineer23]

Lift is not parpendicular to chord line by the way. It is parpendicular to relative airflow

[@goodboyringo9716]

Where are the 5.00 servos , ggg I haven't found a control horn for 5.00

[@onmyworkbench7000]

I just found your channel and I have found it very informative and I like how you get right to the point of the video with out a lot of JABBERING at the start of your videos. How about doing a video on wing sweepback rather than diherdal? It is my undrestanding that every deg. of sweepback is the equivalent to some deg. of dierdal.

[@davidoneworld7759]

Soviet aircraft of the 1960's and 1970's had low wings that were anhedral. Take a look at the Tupolev 134 and 154 and the Ilyushin 62. That seems inherently unstable to me as an Aeronautical engineer. No one has yet explained this paradox. Perhaps you can?

[@RadiationStudio]

I don't think angle of attack is the correct term regarding side-slip, I would use relative air flow. However, I think this video was great and your plane looks great too.

[@Raj_yadav582]

I like your rc/plane

[@MasboyRC]

You change your channel's name sir? I was search your channel for a few weeks 😂

[@keithzhang7194]

How come a electrical motor make sounds like a gas engine?

[@user-jf3pn1dq8z]

What's flight time of NoobTube plane?

[@lasersbee]

Like the Video.... Hate the dog barking..;)

[@spencerboaz2385]

It happens lol , I have a rooster crowing in my last video about my drone .

[@scramjet7466]

i don't understand how a paper plane with no yaw but dihedral flies more stable

[@francesco5254]

Finally! The "more lift" explanation was torturing me :)

[@SsoulBlade]

Motor sounds like a small angry petrol engine. :-)

[@BensMiniToons]

The plane is so loud. lol Though it was switched for a gas plane of the same color.

[@GreyhatInfiltrator]

Electric Flight is very nice indeed. One of the reasons, why I dropped gas-powered airplane.

[@garyshoell9245]

I disagree with this idea of dihedral, firstly you lift is generated 90% to the lifting surface and will try to balance themselves, that how the old fashioned scales work, equal weights and the scales are level, then you say side slip levels the wings, normally enough side slip would be rudder induced and not the way you describe. A plane has a vertical stabiliser which makes the tail follow the the front of the aircraft, the same way weather vanes work, also when a plane is taxiing and encounters a cross wind it will attempt to weather cock.
